Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Basis of Presentation | A. Basis of Presentation – The interim Consolidated Financial Statements of Alcoa Corporation and its subsidiaries (Alcoa Corporation, Alcoa, or the Company) are unaudited. These Consolidated Financial Statements include all adjustments, consisting only of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position, and cash flows. The results reported in these Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the entire year. The 2022 year-end balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP). This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which includes disclosures required by GAAP. In accordance with GAAP, certain situations require management to make estimates based on judgments and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of revenues and expenses during the reporting periods. Management uses historical experience and all available information to make these estimates. Management regularly evaluates the judgments and assumptions used in its estimates, and results could differ from those estimates upon future events and their effects or new information. Certain amounts in previously issued financial statements were reclassified to conform to the current period presentation. Principles of Consolidation. The Consolidated Financial Statements of Alcoa Corporation include the accounts of Alcoa Corporation and companies in which Alcoa Corporation has a controlling interest, including those that comprise the Alcoa World Alumina & Chemicals (AWAC) joint venture (see below). Intercompany transactions have been eliminated. The equity method of accounting is used for investments in affiliates and other joint ventures over which Alcoa Corporation has significant influence but does not have effective control. Investments in affiliates in which Alcoa Corporation cannot exercise significant influence are accounted for at cost less any impairment, a measurement alternative in accordance with GAAP. AWAC is an unincorporated global joint venture between Alcoa Corporation and Alumina Limited and consists of several affiliated operating entities, which own, have an interest in, or operate the bauxite mines and alumina refineries within Alcoa Corporation’s Alumina segment (except for the Poços de Caldas mine and refinery, portions of the São Luís refinery, and investment in Mineração Rio do Norte S.A. (MRN) until its sale in April 2022, all in Brazil) and a portion ( 55 %) of the Portland smelter (Australia) within Alcoa Corporation’s Aluminum segment. Alcoa Corporation owns 60 % and Alumina Limited owns 40 % of these individual entities, which are consolidated by the Company for financial reporting purposes and include Alcoa of Australia Limited (AofA), Alcoa World Alumina LLC (AWA), Alcoa World Alumina Brasil Ltda. (AWAB), and Alúmina Española, S.A. (Española). Alumina Limited’s interest in the equity of such entities is reflected as Noncontrolling interest on the accompanying Consolidated Balance Sheet. |

Segment Reporting [Abstract] | |
Segment Information | E. Segment Information – Alcoa Corporation is a producer of bauxite, alumina, and aluminum products. Beginning in January 2023, the financial information provided to the chief operating decision maker (CODM) for the activities of the bauxite mines and the alumina refineries was combined, and accordingly the Company changed its operating segments. Beginning with the first quarter of 2023, the Company reported its financial results in the following two segments: (i) Alumina, and (ii) Aluminum. Segment information for all prior periods presented has been updated to reflect the new segment structure. Segment performance under Alcoa Corporation’s management reporting system is evaluated based on a number of factors; however, the primary measure of performance is the Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) of each segment. The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; and Research and development expenses. Alcoa Corporation’s Adjusted EBITDA may not be comparable to similarly titled measures of other companies. The CODM function regularly reviews the financial information, including Sales and Adjusted EBITDA, of these two operating segments to assess performance and allocate resources. The operating results of Alcoa Corporation’s reportable segments were as follows (differences between segment totals and consolidated amounts are in Corporate): Alumina Aluminum Total First quarter ended March 31, 2023 Sales: Third-party sales $ 857 $ 1,810 $ 2,667 Intersegment sales 421 3 424 Total sales $ 1,278 $ 1,813 $ 3,091 Segment Adjusted EBITDA $ 103 $ 184 $ 287 Supplemental information: Depreciation, depletion, and amortization $ 77 $ 70 $ 147 Equity loss $ ( 17 ) $ ( 57 ) $ ( 74 ) First quarter ended March 31, 2022 Sales: Third-party sales $ 898 $ 2,388 $ 3,286 Intersegment sales 413 7 420 Total sales $ 1,311 $ 2,395 $ 3,706 Segment Adjusted EBITDA $ 302 $ 713 $ 1,015 Supplemental information: Depreciation, depletion, and amortization $ 85 $ 69 $ 154 Equity income $ 1 $ 39 $ 40 The following table reconciles total Segment Adjusted EBITDA to Consolidated net (loss) income attributable to Alcoa Corporation: First quarter ended 2023 2022 Total Segment Adjusted EBITDA $ 287 $ 1,015 Unallocated amounts: Transformation (1) ( 8 ) ( 14 ) Intersegment eliminations ( 8 ) 100 Corporate expenses (2) ( 30 ) ( 29 ) Provision for depreciation, depletion, and amortization ( 153 ) ( 160 ) Restructuring and other charges, net (D) ( 149 ) ( 125 ) Interest expense ( 26 ) ( 25 ) Other (expenses) income, net (Q) ( 54 ) 14 Other (3) ( 39 ) ( 13 ) Consolidated (loss) income before income taxes ( 180 ) 763 Provision for income taxes ( 52 ) ( 210 ) Net loss (income) attributable to noncontrolling interest 1 ( 84 ) Consolidated net (loss) income attributable to Alcoa Corporation $ ( 231 ) $ 469 (1) Transformation includes, among other items, the Adjusted EBITDA of previously closed operations.

Earnings Per Share [Abstract] | |
Earnings Per Share | F. Earnings Per Share – Basic earnings per share (EPS) amounts are computed by dividing earnings by the average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding. The share information used to compute basic and diluted EPS attributable to Alcoa Corporation common shareholders was as follows (shares in millions): First quarter ended 2023 2022 Net (loss) income attributable to Alcoa Corporation $ ( 231 ) $ 469 Average shares outstanding – basic 178 184 Effect of dilutive securities: Stock options — — Stock units — 4 Average shares outstanding – diluted 178 188 In the first quarter of 2023, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive. Had Alcoa generated net income in the first quarter of 2023 , three million common share equivalents related to three million outstanding stock units and stock options combined would have been included in diluted average shares outstanding for the period. All options to purchase shares of common stock outstanding as of March 31, 2022 were included in the computation of diluted EPS. No options had an exercise price greater than the average market price of Alcoa Corporation’s common stock. |

Alcoa’s share of this adjustment is $ 41 which is included in Other expenses (income), net on the Statement of Consolidated Operations for the quarter ended March 31, 2023. Alcoa’s total share of this dispute of $ 62 includes $ 21 that was recorded in the fourth quarter of 2022. The Company’s basis in the ELYSIS TM Limited Partnership (ELYSIS) as of March 31, 2023 and 2022 , included in Other in the table above, has been reduced to zero for its share of losses incurred to date. As a result, the Company has $ 60 in unrecognized losses as of March 31, 2023 that will be recognized upon additional contributions into the partnership. On February 15, 2022, the Company signed an agreement to sell its share of its investment in MRN in Brazil for $ 10 to South32 Minerals S.A. Related to this transaction, the Company recorded an asset impairment of $ 58 in the first quarter of 2022 in Restructuring and other charges, net on the Statement of Consolidated Operations. On April 30, 2022, Alcoa completed the sale of its investment in MRN. An additional $ 30 in cash could be paid to the Company in the future if certain post-closing conditions related to future MRN mine development are satisfied. |

Receivables [Abstract] | |
Receivables | I. Receivables On January 31, 2023, a wholly-owned special purpose entity (SPE) of the Company entered into a one-year agreement with a financial institution to sell up to $ 150 of certain customer receivables without recourse on a revolving basis. Company subsidiaries sell customer receivables to the SPE, which then transfers the receivables to the financial institution. The Company does not maintain effective control over the transferred receivables, and therefore accounts for the transfers as sales of receivables. Alcoa Corporation guarantees the performance obligations of the Company subsidiaries and unsold customer receivables are pledged as collateral to the financial institution to secure the sold receivables. At March 31, 2023 , the SPE held unsold customer receivables of $ 227 pledged as collateral against the sold receivables. The Company continues to service the customer receivables that were transferred to the financial institution. As Alcoa collects customer payments, the SPE transfers additional receivables to the financial institution rather than remitting cash. In the first quarter of 2023 , the Company sold gross customer receivables of $ 76 , and reinvested collections of $ 23 from previously sold receivables, resulting in net cash proceeds from the financial institution of $ 53 . Cash collections from previously sold receivables yet to be reinvested of $ 34 were included in Accounts payable, trade on the accompanying Consolidated Balance Sheet as of March 31, 2023 . Cash received from sold receivables under the agreement are presented within operating activities in the Statement of Consolidated Cash Flows. |

Goodwill | K. Goodwill As a result of the January 2023 segment change, the Company reviewed the recoverability of the carrying value of goodwill of its Alumina reporting unit in the first quarter of 2023. The estimated fair value of the Alumina reporting unit substantially exceeded the reporting unit’s carrying value, resulting in no impairment. Goodwill, which is included in Other noncurrent assets on the accompanying Consolidated Balance Sheet, was as follows: March 31, 2023 December 31, 2022 Alumina $ 4 $ 4 Aluminum — — Corporate (1) 141 141 $ 145 $ 145 (1) The carrying value of Corporate’s goodwill is net of accumulated impairment losses of $ 742 as of both March 31, 2023 and December 31, 2022. As of March 31, 2023 , the $ 141 of goodwill reflected in Corporate is allocated to Alcoa Corporation’s Alumina reportable segment for purposes of impairment testing. This goodwill is reflected in Corporate for segment reporting purposes because it is not included in management’s assessment of performance by the reportable segment. |

Debt | L. Debt Short-term borrowings Inventory Repurchase Agreement In March 2023, the Company entered into an inventory repurchase agreement whereby the Company sold aluminum to a third party and agreed to subsequently repurchase substantially similar inventory. The Company did not record a sale upon shipment of the inventory and the cash received of $ 25 is recorded in Short-term borrowings within Other current liabilities on the Consolidated Balance Sheet. The inventory sold of $ 25 is pledged as collateral and is reflected in Prepaid expenses and other current assets on the Consolidated Balance Sheet. The cash received under the inventory repurchase agreement is included in Cash provided from (used for) financing activities on the Statement of Consolidated Cash Flows for the quarter ended March 31, 2023. Credit Facilities Revolving Credit Facility The Company has an unsecured $ 1,250 revolving credit and letter of credit facility in place for working capital and/or other general corporate purposes (the Revolving Credit Facility). The Revolving Credit Facility established on September 16, 2016 and amended and restated in 2022, is scheduled to mature in June 2027 . Subject to the terms and conditions under the Revolving Credit Facility, the Company may borrow funds or issue letters of credit through its Alcoa Corporation or Alcoa Nederland Holding B.V. (ANHBV) legal entities. See Part II Item 8 of Alcoa Corporation’s Annual Report on Form 10-K in Note M to the Consolidated Financial Statements for the year ended December 31, 2022 for more information on the Revolving Credit Facility. As of March 31, 2023 , the Company was in compliance with all covenants. The Company may access the entire amount of commitments under the Revolving Credit Facility. There were no borrowings outstanding at March 31, 2023 and December 31, 2022 , and no amounts were borrowed during the first quarters ended March 31, 2023 and March 31, 2022 under the Revolving Credit Facility. ANHBV Credit Facility In April 2023, Alcoa Corporation and ANHBV, a wholly-owned subsidiary of Alcoa Corporation and the borrower, entered into a one-year unsecured revolving credit facility for $ 250 (available to be drawn in Japanese yen). The facility includes covenants that are substantially the same as those included in the Revolving Credit Facility. If Alcoa Corporation or ANHBV, as applicable, fails to have a rating of at least Ba1 from Moody’s Investor Service (Moody’s) and BB+ from Standard and Poor’s Global Ratings (S&P), then no lending party to this facility would have any commitment or obligation to lend to the borrower, ANHBV. |

Funding and Cash Flows. It is Alcoa’s policy to fund amounts for defined benefit pension plans sufficient to meet the minimum requirements set forth in each applicable country's benefits laws and tax laws, including the Employee Retirement Income Security Act of 1974 (ERISA) for U.S. plans. From time to time, the Company contributes additional amounts as deemed appropriate. Under ERISA regulations, a plan sponsor that establishes a pre-funding balance by making discretionary contributions to a U.S. defined benefit pension plan may elect to apply all or a portion of this balance toward its minimum required contribution obligations to the related plan in future years. In the first quarter of 2023, management made such elections related to the Company’s U.S. plans and intends to do so for the remainder of 2023. As a result, Alcoa’s minimum required contribution to defined benefit pension plans in 2023 is estimated to be approximately $ 20 , of which approximately $ 4 was contributed to non-U.S. plans during the first quarter of 2023. In the first quarter of 2022 , $ 4 was contributed to non-U.S. plans. |

Fair Value Disclosures [Abstract] | |
Derivatives and Other Financial Instruments | N. Derivatives and Other Financial Instruments Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: • Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. • Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3 - Inputs that are both significant to the fair value measurement and unobservable. Derivatives Alcoa Corporation is exposed to certain risks relating to its ongoing business operations, including the risks of changing commodity prices, foreign currency exchange rates and interest rates. Alcoa Corporation’s commodity and derivative activities include aluminum, energy, foreign exchange, and interest rate contracts which are held for purposes other than trading. They are used to mitigate uncertainty and volatility, and to cover underlying exposures. While Alcoa does not generally enter into derivative contracts to mitigate the risk associated with changes in aluminum price, the Company may do so in isolated cases to address discrete commercial or operational conditions. Alcoa is not involved in trading activities for energy, weather derivatives, or other nonexchange commodity trading activities. Alcoa Corporation’s aluminum and foreign exchange contracts are predominantly classified as Level 1 under the fair value hierarchy. All of the Level 1 contracts are designated as either fair value or cash flow hedging instruments (except as described below). Alcoa Corporation also has several derivative instruments classified as Level 3 under the fair value hierarchy, which are either designated as cash flow hedges or undesignated. Alcoa includes the changes in its equity method investee’s Level 2 derivatives in Accumulated other comprehensive loss in the accompanying Consolidated Balance Sheet. The following tables present the detail for Level 1 and 3 derivatives (see additional Level 3 information in further tables below): March 31, 2023 December 31, 2022 Assets Liabilities Assets Liabilities Level 1 derivative instruments $ 49 $ 13 $ 84 $ 14 Level 3 derivative instruments 58 1,316 52 1,212 Total $ 107 $ 1,329 $ 136 $ 1,226 Less: Current 106 213 134 200 Noncurrent $ 1 $ 1,116 $ 2 $ 1,026 2023 2022 First quarter ended March 31, Unrealized loss recognized in Other comprehensive loss Realized gain (loss) reclassed from Other comprehensive loss to earnings Unrealized (loss) gain recognized in Other comprehensive loss Realized loss reclassed from Other comprehensive loss to earnings Level 1 derivative instruments $ ( 11 ) $ 16 $ ( 233 ) $ ( 6 ) Level 3 derivative instruments ( 174 ) ( 52 ) ( 837 ) ( 104 ) Noncontrolling and equity interest (Level 2) ( 2 ) ( 1 ) 7 ( 4 ) Total $ ( 187 ) $ ( 37 ) $ ( 1,063 ) $ ( 114 ) For the quarter ended March 31, 2023 , the realized gain of $ 16 on Level 1 cash flow hedges was recognized in Sales.

Additionally, Alcoa uses Level 1 aluminum derivative instruments to manage exposures to changes in the LME associated with the Alumar (Brazil) restart (expires December 2023 ) and the San Ciprián strike (expired October 2022 ). Alcoa Corporation uses Level 1 foreign exchange forward contracts to mitigate the risk of foreign exchange exposure related to euro power purchases in Norway (expires December 2026 ), krone capital expenditures in Norway (expires June 2025 ), and U.S. dollar alumina and aluminum sales in Brazil (expires December 2024 ).

The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash equivalents and Restricted cash were classified in Level 1 of the fair value hierarchy. Short-term borrowings and Long-term debt, including amounts due within one year. The fair value of Long-term debt, less amounts due within one year was based on quoted market prices for public debt and on interest rates that are currently available to Alcoa Corporation for issuance of debt with similar terms and maturities for non-public debt.

Income Taxes | O. Income Taxes – Alcoa Corporation’s estimated annualized effective tax rate (AETR) for 2023 as of March 31, 2023 differs from the U.S. federal statutory rate of 21 % primarily due to foreign jurisdictions with higher statutory tax rates in addition to losses in certain jurisdictions with full valuation allowances resulting in no tax benefit. Three months ended March 31, 2023 2022 (Loss) income before income taxes $ ( 180 ) $ 763 Estimated annualized effective tax rate 141.4 % 26.4 % Income tax (benefit) expense $ ( 255 ) $ 202 Unfavorable tax impact related to losses in jurisdictions with no tax benefit 305 7 Discrete tax expense 2 1 Provision for income taxes $ 52 $ 210 The Company’s subsidiaries in Iceland have a full valuation allowance recorded against deferred tax assets, which was established in 2015 and 2017, as the Company believes it is more likely than not that these tax benefits will not be realized. If current market conditions were to continue or improve, management may conclude that Iceland’s deferred tax assets may be realized, resulting in a future reversal of the valuation allowance, generating a non-cash benefit in the period recorded. Iceland’s net deferred tax assets, excluding the valuation allowance, were $ 103 as of March 31, 2023. On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022 (IRA), which includes a 15 % minimum tax on book income of certain large corporations, a 1 % excise tax on net stock repurchases after December 31, 2022, and several tax incentives to promote clean energy. As a result of the provisions of the IRA, we will incur an excise tax of 1 % for a ny common stock repurchases made subsequent to December 31, 2022, which will be reflected in the cost of purchasing the underlying shares. The minimum corporate tax will not have an impact on the Company for 2023. The IRA contains a number of tax credits and other incentives for investments in renewable energy production, carbon capture, and other climate actions, as well as the production of critical minerals. These provisions may result in an incremental benefit to the Company. However, given the complexity and uncertainty around the applicability of the incentives to our specific facts and circumstances, we continue to analyze the IRA provisions and seek clarity from relevant government entities to identify and quantify potential opportunities and applicable benefits included in the legislation. At this time the applicability of those provisions to the Company’s specific facts and circumstances are uncertain, and an estimate of those benefits has not been recorded. |

Contingencies | P. Contingencies Environmental Matters Alcoa Corporation participates in environmental assessments and cleanups at several locations. These include currently or previously owned or operated facilities and adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)) sites. Alcoa Corporation’s environmental remediation reserve balance reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. The following table details the changes in the carrying value of recorded environmental remediation reserves: Balance at December 31, 2021 $ 309 Liabilities incurred 32 Cash payments ( 26 ) Reversals of previously recorded liabilities ( 30 ) Foreign currency translation and other ( 1 ) Balance at December 31, 2022 284 Liabilities incurred 14 Cash payments ( 7 ) Reversals of previously recorded liabilities ( 1 ) Foreign currency translation and other 1 Balance at March 31, 2023 $ 291 At March 31, 2023 and December 31, 2022 , the current portion of the environmental remediation reserve balance was $ 61 and $ 58 , respectively. In the first quarter of 2023, the Company incurred liabilities of $ 14 primarily related to the closure of the previously curtailed Intalco aluminum smelter, which was recorded in Restructuring and other charges, net on the accompanying Statement of Consolidated Operations (see Note D). Payments related to remediation expenses applied against the reserve were $ 7 in the first quarter of 2023. These amounts include mandated expenditures as well as those not required by any regulatory authority or third party. Further, the Company recorded a reversal of a reserve of $ 1 due to the determination that certain remaining site remediation is no longer required. In the first quarter of 2022, the Company incurred liabilities of $ 5 primarily related to a new phase of work at the former East St. Louis site, which was recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. Payments related to remediation expenses applied against the reserve were $ 4 in the first quarter of 2022 . These amounts include mandated expenditures as well as those not required by any regulatory authority or third party. Further, the Company recorded a reversal of a reserve of $ 2 due to the determination that certain remaining site remediation is no longer required. The estimated timing of cash outflows on the environmental remediation reserve at March 31, 2023 is as follows: 2023 (excluding the three months ended March 31, 2023) $ 53 2024 - 2028 178 Thereafter 60 Total $ 291 Reserve balances at March 31, 2023 and December 31, 2022 , associated with significant sites with active remediation underway or for future remediation were $ 234 and $ 234 , respectively. In management’s judgment, the Company’s reserves are sufficient to satisfy the provisions of the respective action plans. Upon changes in facts or circumstances, a change to the reserve may be required. The Company’s significant sites include: Suriname —The reserve associated with the 2017 closure of the Suralco refinery and bauxite mine is for treatment and disposal of refinery waste and soil remediation. The work began in 2017 and is expected to be completed at the end of 2025. Hurricane Creek, Arkansas —The reserve associated with the 1990 closure of two mining areas and refineries near Hurricane Creek, Arkansas is for ongoing monitoring and maintenance for water quality surrounding the mine areas and residue disposal areas. Massena, New York —The reserve associated with the 2015 closure of the Massena East smelter by the Company’s subsidiary, Reynolds Metals Company, is for subsurface soil remediation to be performed after demolition of the structures. Remediation work commenced in 2021 and will take four to eight years to complete. Point Comfort, Texas —The reserve associated with the 2019 closure of the Point Comfort alumina refinery is for disposal of industrial wastes contained at the site, subsurface remediation, and post-closure monitoring and maintenance. The final remediation plan is currently under review, which may result in a change to the existing reserve. Sherwin, Texas —In connection with the 2018 settlement of a dispute related to the previously-owned Sherwin alumina refinery, the Company’s subsidiary, Copano Enterprises LLC, accepted responsibility for the final closure of four bauxite residue waste disposal areas (known as the Copano facility). Work commenced on the first residue disposal area in 2018 and will take up to three additional years to complete, depending on the nature of its potential re-use. Other than ongoing maintenance and repair activities, work on the next three areas has not commenced but is expected to be completed by 2048, depending on its potential re-use. Longview, Washington —In connection with a 2018 Consent Decree and Cleanup Action Plan with the State of Washington Department of Ecology, the Company’s subsidiary, Northwest Alloys as landowner, accepted certain responsibilities for future remediation of contaminated soil and sediments at the site located near Longview, Washington. In December 2020, the lessee of the land, who was a partner in the remediation of the site, filed for bankruptcy and exited the site in January 2021. Remediation design changes for consolidation and remediation of the onsite industrial waste landfills, groundwater remediation, and post-closure monitoring and maintenance at the site was completed in 2021. Addy, Washington —The reserve associated with the 2022 closure of the Addy magnesium smelter facility is for site-wide remediation and investigation and post-closure monitoring and maintenance. Remediation work is not expected to begin until 2024 and will take three to five years to complete. The final remediation plan is currently being developed, which may result in a change to the existing reserve. Ferndale, Washington — The reserve associated with the 2023 closure of the Intalco aluminum smelter in Ferndale, Washington is for below grade site remediation and five years of post-closure maintenance and monitoring. The final remediation plan is under review but is expected to be completed in three years . Other Sites —The Company is in the process of decommissioning various other plants and remediating sites in several countries for potential redevelopment or to return the land to a natural state. In aggregate, there are remediation projects at 32 other sites that are planned or underway. These activities will be completed at various times in the future with the latest expected to be in 2026, after which ongoing monitoring and other activities may be required. At March 31, 2023 and December 31, 2022 , the reserve balance associated with these activities was $ 57 and $ 50 , respectively. Tax Brazil (AWAB) —In March 2013, AWAB was notified by the Brazilian Federal Revenue Office (RFB) that approximately $ 110 (R$ 220 ) of value added tax credits previously claimed were being disallowed and a penalty of 50 % was assessed. Of this amount, AWAB received $ 41 (R$ 82 ) in cash in May 2012. The value added tax credits were claimed by AWAB for both fixed assets and export sales related to the Juruti bauxite mine and São Luís refinery expansion for tax years 2009 through 2011. The RFB has disallowed credits they allege belong to the consortium in which AWAB owns an interest and should not have been claimed by AWAB. Credits have also been disallowed as a result of challenges to apportionment methods used, questions about the use of the credits, and an alleged lack of documented proof. AWAB presented defense of its claim to the RFB on April 8, 2013. In February 2022, the RFB notified AWAB that it had inspected the value added tax credits claimed for 2012 and disallowed $ 4 (R$ 19 ). In its decision, the RFB allowed credits of $ 14 (R$ 65 ) that were similar to those previously disallowed for 2009 through 2011. In July 2022, the RFB notified AWAB that it had inspected the value added tax credits claimed for 2013 and disallowed $ 13 (R$ 70 ). In its decision, the RFB allowed credits of $ 16 (R$ 84 ) that were similar to those previously disallowed for 2009 through 2011. The decisions on the 2012 and 2013 credits provide positive evidence to support management’s opinion that there is no basis for these credits to be disallowed. AWAB received the 2012 allowed credits with interest of $ 9 (R$ 44 ) in March 2022 and the 2013 allowed credits with interest of $ 6 (R$ 31 ) in August 2022. AWAB will continue to dispute the credits that were disallowed for 2012 and 2013. If AWAB is successful in this administrative process, the RFB would have no further recourse. If unsuccessful in this process, AWAB has the option to litigate at a judicial level. Separately from AWAB’s administrative appeal, in June 2015, a new tax law was enacted repealing the provisions in the tax code that were the basis for the RFB assessing a 50 % penalty in this matter. As such, the estimated range of reasonably possible loss for these matters is $ 0 to $ 46 (R$ 239 ). It is management’s opinion that the allegations have no basis; however, at this time, the Company is unable to reasonably predict an outcome for this matter. Australia (AofA) —In December 2019, AofA received a statement of audit position (SOAP) from the Australian Taxation Office (ATO) related to the pricing of certain historic third-party alumina sales. The SOAP proposed adjustments that would result in additional income tax payable by AofA. During 2020, the SOAP was the subject of an independent review process within the ATO. At the conclusion of this process, the ATO determined to continue with the proposed adjustments and issued Notices of Assessment (the Notices) that were received by AofA on July 7, 2020. The Notices asserted claims for income tax payable by AofA of approximately $ 143 (A$ 214 ). The Notices also included claims for compounded interest on the tax amount totaling approximately $ 474 (A$ 707 ). On September 17, 2020, the ATO issued a position paper with its preliminary view on the imposition of administrative penalties related to the tax assessment issued to AofA. This paper proposed penalties of approximately $ 86 (A$ 128 ). AofA disagreed with the Notices and with the ATO’s proposed position on penalties. In September 2020, AofA lodged formal objections to the Notices. In the fourth quarter of 2020, AofA provided a submission on the ATO’s imposition of interest and also submitted a response to the ATO’s position paper on penalties. After the ATO completes its review of AofA’s response to the penalties position paper, the ATO could issue a penalty assessment. To date, AofA has not received a response to its submission on the ATO’s imposition of interest or its response to the ATO’s position paper on penalties. Through February 1, 2022, AofA did not receive a response from the ATO on AofA’s formal objections to the Notices and, on that date, AofA submitted statutory notices to the ATO requiring the ATO to make decisions on AofA’s objections within a 60-day period. On April 1, 2022, the ATO issued its decision disallowing the Company’s objections related to the income tax assessment, while the position on penalties and interest remains outstanding. On April 29, 2022, AofA filed proceedings in the Australian Administrative Appeals Tribunal (AAT) against the ATO to contest the Notices, a process which could last several years. The AAT held the first directions hearing on July 25, 2022 ordering AofA to file its evidence and related materials by November 4, 2022, ATO to file its materials by April 14, 2023 and AofA to file reply materials by May 26, 2023. AofA filed its evidence and related materials on November 4, 2022. The ATO did not file its materials by April 14, 2023. The ATO has sought an extension of time to file its materials, which will be determined at a directions hearing on May 17, 2023. The Company maintains that the sales subject to the ATO’s review, which were ultimately sold to Aluminium Bahrain B.S.C., were the result of arm’s length transactions by AofA over two decades and were made at arm’s length prices consistent with the prices paid by other third-party alumina customers. In accordance with the ATO’s dispute resolution practices, AofA paid 50 % of the assessed income tax amount exclusive of interest and any penalties, or approximately $ 74 (A$ 107 ), during the third quarter 2020, and the ATO is not expected to seek further payment prior to final resolution of the matter. If AofA is ultimately successful, any amounts paid to the ATO as part of the 50 % payment would be refunded. AofA funded the payment with cash on hand and recorded the payment within Other noncurrent assets as a noncurrent prepaid tax asset; the related March 31, 2023 balance is $ 72 (A$ 107 ). Further interest on the unpaid tax will continue to accrue during the dispute. The initial interest assessment and the additional interest accrued are deductible against taxable income by AofA but would be taxable as income in the year the dispute is resolved if AofA is ultimately successful. AofA applied this deduction beginning in the third quarter of 2020, reducing cash tax payments. At March 31, 2023 and December 31, 2022 , total reductions in cash tax payments were $ 179 (A$ 268 ) and $ 174 (A$ 260 ), respectively, and are reflected within Other noncurrent liabilities and deferred credits as a noncurrent accrued tax liability. The Company continues to believe it is more likely than not that AofA’s tax position will be sustained and therefore is not recognizing any tax expense in relation to this matter. However, because the ultimate resolution of this matter is uncertain at this time, the Company cannot predict the potential loss or range of loss associated with the outcome, which may materially affect its results of operations and financial condition. References to any assessed U.S. dollar amounts presented in connection with this matter have been converted into U.S. dollars from Australian dollars based on the exchange rate in the respective period. AofA is part of the Company’s joint venture with Alumina Limited, an Australian public company listed on the Australian Securities Exchange. The Company and Alumina Limited own 60 % and 40 %, respectively, of the joint venture entities, including AofA. Other Spain —In July 2019, the Company completed the divestiture of the Avilés and La Coruña aluminum facilities to PARTER Capital Group AG (PARTER) in a sale process endorsed by the Spanish government and supported by the workers’ representatives following a collective dismissal process. In early 2020, PARTER sold a majority stake in the facilities to an unrelated party. Alcoa had no knowledge of the subsequent transaction prior to its announcement and on August 28, 2020, Alcoa filed a lawsuit with the Court of First Instance in Madrid, Spain asserting that the sale was in breach of the sale agreement between Alcoa and PARTER. Related to this subsequent sale transaction, certain proceedings and investigations have been initiated by or at the request of the employees of the facilities against their current employers, the new owners of the current employers, and Alcoa, alleging that certain agreements from the 2019 collective dismissal process remain in force and that, under such agreements, Alcoa remains liable for certain related employment benefits. One such proceeding is a collective case before the Spanish National Court, filed on November 10, 2020, wherein the workers’ representatives and employees are seeking to have the terms of a Collective Dismissal Agreement signed between Alcoa and the workers in January 2019 be fulfilled. Other proceedings include: a second collective claim filed in National Court on behalf of employees that were not affected by the 2019 collective dismissal process, numerous individual labor claims filed in the labor courts of Avilés and La Coruña and the initiation of a separate criminal investigation by the National Court. On June 15, 2021, the Spanish National Court ruled that the collective dismissal agreement for the divested Avilés and La Coruña aluminum facilities should be applied to the situation of the claimant workers, and that Alcoa should be liable for the severance of those employees to the extent they were affected by the 2019 collective dismissal process. Alcoa appealed this ruling to the Supreme Court of Spain. In July 2021, the Spanish National Court appointed a judicial director to oversee the facilities and later declared the facilities insolvent. In early 2022, the insolvency administrators appointed by the courts (one for each facility) announced their intention to collectively dismiss all employees at the two facilities. In the first quarter of 2022, the Company recorded a charge of $ 77 in Restructuring and other charges, net to reflect its estimate for the agreement reached with the workers of the divested Avilés and La Coruña facilities to settle various legal disputes related to the 2019 divestiture. In April 2022, the Company received unanimous acceptance of an offer made to all active workers of the divested Avilés and La Coruña facilities and a Global Settlement Agreement (GSA) was fully executed. The Company expects to make cash payments in 2023 upon completion of certain administrative and judicial approvals. General In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against Alcoa Corporation, including those pertaining to environmental, safety and health, commercial, tax, product liability, intellectual property infringement, employment, and employee and retiree benefit matters, and other actions and claims arising out of the normal course of business. While the amounts claimed in these other matters may be substantial, the ultimate liability is not readily determinable because of the considerable uncertainties that exist. Accordingly, it is possible that the Company’s liquidity or results of operations in a particular period could be materially affected by one or more of these other matters. However, based on facts currently available, management believes that the disposition of these other matters that are pending or asserted will not have a material adverse effect, individually or in the aggregate, on the financial position of the Company. |

Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Basis of Presentation | A. Basis of Presentation – The interim Consolidated Financial Statements of Alcoa Corporation and its subsidiaries (Alcoa Corporation, Alcoa, or the Company) are unaudited. These Consolidated Financial Statements include all adjustments, consisting only of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position, and cash flows. The results reported in these Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the entire year. The 2022 year-end balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP). This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which includes disclosures required by GAAP. In accordance with GAAP, certain situations require management to make estimates based on judgments and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of revenues and expenses during the reporting periods. Management uses historical experience and all available information to make these estimates. Management regularly evaluates the judgments and assumptions used in its estimates, and results could differ from those estimates upon future events and their effects or new information. Certain amounts in previously issued financial statements were reclassified to conform to the current period presentation. |
Principles of Consolidation | Principles of Consolidation. The Consolidated Financial Statements of Alcoa Corporation include the accounts of Alcoa Corporation and companies in which Alcoa Corporation has a controlling interest, including those that comprise the Alcoa World Alumina & Chemicals (AWAC) joint venture (see below). Intercompany transactions have been eliminated. The equity method of accounting is used for investments in affiliates and other joint ventures over which Alcoa Corporation has significant influence but does not have effective control. Investments in affiliates in which Alcoa Corporation cannot exercise significant influence are accounted for at cost less any impairment, a measurement alternative in accordance with GAAP. AWAC is an unincorporated global joint venture between Alcoa Corporation and Alumina Limited and consists of several affiliated operating entities, which own, have an interest in, or operate the bauxite mines and alumina refineries within Alcoa Corporation’s Alumina segment (except for the Poços de Caldas mine and refinery, portions of the São Luís refinery, and investment in Mineração Rio do Norte S.A. (MRN) until its sale in April 2022, all in Brazil) and a portion ( 55 %) of the Portland smelter (Australia) within Alcoa Corporation’s Aluminum segment. Alcoa Corporation owns 60 % and Alumina Limited owns 40 % of these individual entities, which are consolidated by the Company for financial reporting purposes and include Alcoa of Australia Limited (AofA), Alcoa World Alumina LLC (AWA), Alcoa World Alumina Brasil Ltda. (AWAB), and Alúmina Española, S.A. (Española). Alumina Limited’s interest in the equity of such entities is reflected as Noncontrolling interest on the accompanying Consolidated Balance Sheet. |
