Consolidated Statements of Cash Flows, page 34
- ----------------------------------------------

     1.   Please tell us where the amortization of your capitalized debt
          issuance costs and intangible assets which are included in Other
          Assets appear on your cash flow statement. Also tell us what is being
          captured in you investing activity labeled "change in other
          non-current assets".

          Response to Comment 1
          ---------------------

          In our cash flow statement, the amortization of our capitalized debt
          service cost is included in investing activities under the caption
          labeled "change in other non-





          current assets" in the approximate amounts of $73 thousand, $85
          thousand and $60 thousand for the for years ended December 31, 2004,
          2003 and 2002, respectively. Amortization of our intangible assets is
          included in cash flow from operating activities under the caption
          labeled "amortization".

          We will revise future filings to classify the amortization of
          capitalized debt service cost as an operating activity.

Revenue Recognition, page 39
- ----------------------------

     2.   We read in the description of your business that your clad metal
          products are produced, and your welding services are provided, on a
          project-by-project basis based on specifications set forth in
          customers' purchase orders. Given this disclosure, it is not clear if
          your sales have customer acceptance provisions. Please tell us and
          revise future filings to describe the nature of any customer
          acceptance provisions and address how they impact your revenue
          recognition.

          Response to Comment 2
          ---------------------

          Sales of clad metal products are generally based upon customer
          specifications set forth in customer purchase orders and require us to
          provide certifications relative to the metals used and the results of
          any non-destructive testing that the customer has requested be
          performed on clad plates. Any non-conformance issues with respect to
          metal specification and non-destructive testing are resolved before
          the product is shipped and billed. The welding services provided by
          AMK Welding are performed based upon welding specifications provided
          by its customers. AMK supplies its customers with certifications
          regarding the proper application of customer-specified welding
          procedures. In the rare circumstances in which a customer requires its
          own inspection or third-party inspection services before clad metal
          products or welding services are accepted, such inspections are
          completed and customer acceptance criteria are satisfied before
          products are shipped and the customer is billed. We will revise future
          filings to clarify these matters.

     3.   We read that you recognize revenue using the completed contract
          method. Based on your description of this method, it is not clear to
          us how your revenue recognition policy differs from a policy of
          recognizing revenue as it is realizable and earned as indicated by the
          four criteria specified in SAB Topic 13A. Furthermore, based on your
          description of the business and the contracts into which you enter, it
          is not clear to us that your sales qualify for the use of the
          completed contract method of revenue recognition as that method is
          defined in SOP 81-1. Please educate us further on your revenue
          recognition policy and revise future filings to clarify this issue.





        Response to Comment 3
        ---------------------

        The contracts that we refer to in our revenue recognition policy are
        customer purchase orders that generally contain several line items for
        the specific clad plates being ordered and/or a line item for several
        units of an identical clad plate. Each individual item specified in a
        customer purchase order has a fixed unit price. As individual items from
        purchase orders are shipped, revenue is recognized only for the units
        included in each individual shipment. In evaluating revenue recognition
        decisions with respect to individual customer orders, we carefully
        consider the four criteria specified in SAB Topic 13A and recognize
        revenue only when all four criteria are met. We agree that our customer
        orders are not long-term construction-type contracts under SOP 81-1 and
        are thus of the opinion that the completed contract method of revenue
        recognition as defined in SOP 81-1 does not apply to our sales. We will
        revise future filings clarify our revenue recognition policy.

     4.   We note that you provide services through both a long-term contract
          for shock synthesis of industrial diamonds and your AMK Welding
          segment. Please tell us and revise future filings to describe your
          revenue recognition policy for these services. Supplementally tell us
          the revenues generated by the long-term contract for shock synthesis
          for each year presented on your operating statement. Also tell us how
          you determined that you did not need to provide the disclosures
          related to receivables and inventories associated with long-term
          contracts as required by Rule 5-02(3) and (6) of Regulation S-X.

          Response to Comment 4
          ---------------------

          AMK Welding provides welding services principally to the commercial
          and military aircraft engine markets and to the power generation
          industry and is not involved in any long-term contracts. AMK's welding
          services are provided on a project-by-project basis based on
          specifications set forth in customer purchase orders. Upon receipt of
          an order for welded assemblies, AMK performs welding services on
          customer-owned and supplied parts using customer-specified welding
          procedures. In addition to its welding services, AMK also provides
          various special stress relief and non-destructive examination
          processes such as radiographic inspection in support of its welding
          operations. Upon completion of all required welding, stress relief and
          non-destructive testing services, welded assemblies are shipped to the
          customer and revenue is recognized.

          With respect to services relating to the shock synthesis of industrial
          diamonds, the Company provides such services under a "Tolling/Services
          Agreement for Industrial Diamonds", which is cancelable by either
          party upon nine months written notice. Under this service agreement,
          the Company is required to manufacture high-density ammonium nitrate
          explosives and detonate such explosives around industrial diamond
          assemblies provided by the customer. The terms of the agreement
          require the customer to pay a "Service Fee" for the





          services provided on each assembly and a "Raw Material Fee" in the
          amount of the Company's reasonable cost of the explosives and other
          raw materials directly related to the services provided on each
          assembly. As monthly services are rendered, the Service Fee and Raw
          Material Fee for each diamond assembly are billed and recorded as
          revenue only after the services have been completed for that assembly
          and the assembly has been shipped to the customer. For the years ended
          December 31, 2004, 2003 and 2003, the Company recognized aggregate
          revenues of approximately $744 thousand, $314 thousand $661 thousand,
          respectively, for industrial diamond shock synthesis services.

          Based upon the nature of the above-described services provided by AMK
          Welding to its customers under individual purchase orders and the
          industrial diamond shock synthesis services provided by our Explosive
          Metalworking Group under the service contract as described above, we
          do not believe that disclosures related to receivables and inventories
          associated with long-term contracts as required by Rule 5-02(3) and
          (6) of Regulation S-X are applicable to any of the Company's
          contracts.

          We will revise future filings to more fully describe our revenue
          recognition policy and to eliminate the use of the term "long-term
          contracts".

     5.   In future filings please disclose any securities that were not
          included in your computation of diluted EPS because to do so would
          have been antidilutive for the periods presented. Refer to paragraph
          40(c) of SFAS 128.

          Response to Comment 5
          ---------------------

          In future filings, we will disclose any securities that are not
          included in our computation of diluted EPS because to do so would be
          antidilutive for any of the period presented.

Note 3 - Debt, page 44
- ----------------------

     6.   We read that your French bank term loan allows the bank to demand
          early repayment of any outstanding loans if Groupe SNPE's indirect
          ownership of Nobelclad falls below 50%. Please explain to us in more
          detail why this is a clause in your loan agreement. Please tell us if
          Groupe SNPE has guaranteed your repayment of this loan to the French
          bank.

          Response to Comment 6
          ---------------------

          The term loan provided to Nobelclad Europe ("Nobelclad") by a French
          bank relates to Nobelclad's acquisition of Nitro Metall AB in June of
          2001 from Nobel Explosifs France ("NEF"), a wholly owned subsidiary of
          Groupe SNPE. At the time the loan was issued, Noblelclad, a former
          division of NEF, had operated as a





          stand-alone legal entity for less than a year and the French bank was
          aware of NEF's intent to sell Nobelclad to DMC within a few weeks of
          the loan being issued. Based on these considerations and the fact that
          the loan agreement contains no financial covenants, it is our
          understanding that the French bank requested that the loan agreement
          include a provision allowing it to demand early repayment of any
          outstanding loans if Groupe SNPE's indirect ownership of Nobelclad
          were to fall below 50%. Groupe SNPE, which holds four of seven seats
          on the DMC Board of Directors and owns approximately 52% of DMC, has
          clearly communicated its intent to retain its controlling interest in
          DMC for the indefinite future. To the best of our knowledge, Groupe
          SNPE has not formally guaranteed repayment of this loan.

     7.   We note that you took you insurance coverage into account when
          concluding that the outcome of any pending actions will not have a
          material adverse effect on your financial statements. We have the
          following comments:

          o    We remind you that SFAS 5 does not allow you to record any
               expected insurance recoveries until they have been realized.
               Refer to paragraph 17. Please confirm to us that you are not
               netting any expected insurance recoveries against liabilities for
               pending claims. Also confirm to us that, regardless of the
               expected impact on your insurance coverage, you have disclosed
               pending actions that are reasonably possible and recorded an
               accrual for pending actions that are probable and reasonably
               estimable.

          o    In future filings, please disclose your accounting policy for
               recording insurance recoveries.

          Response to Comment 7
          ---------------------

          The referenced disclosure is a general disclosure that we have made in
          our commitments and contingencies note for a number of years. We
          hereby confirm that we do not net expected insurance recoveries
          against liabilities for pending claims. We also confirm that there
          were no pending actions that required disclosure and that it is our
          practice to record accruals for pending actions that are probable and
          reasonably estimable in accordance with SFAS 5.

          In future filings, we will disclose our accounting policy for
          recording insurance recoveries if it becomes material.

Note 8 - Discontinued Operations, page 53
- -----------------------------------------

     8.   We note your discussion of the divestiture of your Spin Forge division
          in 2004 and that you have reclassified the assets, liabilities, and
          results of this division as discontinued operations in your financial
          statements. We read that you sold the





          inventory related to this division, that you are leasing to a third
          party the manufacturing equipment and tooling related to this division
          through an initial lease term of January 1, 2007, and that you are
          also subleasing to this third party the real estate associated with
          this division. Given that the majority of your Spin Forge division's
          assets were leased or subleased to a third party at December 31, 2004,
          and are recorded as assets on your books at December 31, 2004, it does
          not appear that the assets of this division were disposed of during
          2004. Based on our review of the related leases, your Spin Forge
          division does not appear to qualify as held for sale as defined in
          paragraph 30 of SFAS 144. As indicated in paragraph 42 of SFAS 144,
          the classification of a component of an entity as discontinued
          operations is only appropriate if that component has been disposed of
          or is classified as held for sale. Please help us to understand how
          you determined that it was appropriate to classify this division as a
          discontinued operation at December 31, 2004, and tell us the
          accounting guidance that you relied upon.

          Response to Comment 8
          ---------------------

          On September 17, 2004, the Company completed the divestiture of its
          Spin Forge business ("Spin Forge"), which manufactures certain rocket
          motor cases and pressure tanks. The divestiture was made pursuant to
          an Agreement, dated as of September 17, 2004 (the "Master Agreement"),
          between DMC and Aerojet-General Corporation ("Aerojet"). Pursuant to
          the Master Agreement, DMC sold the assets that constitute Spin Forge,
          excluding certain equipment and real estate, which are being leased or
          subleased to Aerojet, for a sales price of approximately $1,665,000.
          It is important to note that all of the Spin Forge employees became
          employees of Aerojet on the closing date and that Aerojet assumed
          total responsibility for all going forward business operations and
          related liabilities.

          In connection with the Master Agreement, DMC agreed to lease all of
          the Spin Forge manufacturing equipment and tooling to Aerojet pursuant
          to a separate Equipment Lease Agreement (the "Equipment Lease"), dated
          as of September 17, 2004, between DMC and Aerojet. Aerojet pays DMC
          monthly rental installments of $21,921 under the Equipment Lease,
          which will terminate on January 1, 2007 unless extended at Aerojet's
          option until September 17, 2012. At the end of the initial term,
          Aerojet has the option to purchase all or a portion of the equipment
          being leased at its net book value as of the lease commencement date,
          less any rental installments paid pursuant to the Equipment Lease. The
          Equipment Lease is considered to be a financing vehicle that enabled
          DMC to obtain the best price possible for the divestiture of a
          business that was incurring significant operating losses.

          Each of the following six criteria must be met in order for a
          long-lived asset to be classified as "held for sale":

               1.   Management, having the authority to approve the action,
                    commits to a plan to sell the long-lived asset or disposal
                    group.





               2.   The asset or disposal group is available for immediate sale
                    in its present condition subject only to the terms that are
                    usual or customary for sales of such assets (disposal
                    groups).
               3.   An active program to locate a buyer, and other actions
                    required to complete the plan to sell, have been initiated.
               4.   The sale of the asset or disposal group is probable and the
                    transfer is expected to qualify for recognition as a
                    completed sale within one year, with several exceptions.
               5.   The long-lived asset or disposal group is being actively
                    marketed for sale at a price that is reasonable in relation
                    to its current fair value.
               6.   Actions necessary to complete the plan indicate that it is
                    unlikely that significant changes to the plan will be made
                    or that the plan will be withdrawn.

          As mentioned above, DMC's Equipment Lease with Aerojet was viewed as a
          financing vehicle that enabled the Company to obtain the best price
          possible for Spin Forge. We are not engaged in the commercial leasing
          business and have no further use of the property that is being leased
          to Aerojet. Additionally, if the Company had not consummated the sale
          to Aerojet, Company management and its Board of Directors was
          committed to the orderly shutdown of the Spin Forge business
          operations, including liquidation of the manufacturing equipment and
          tooling. In recording the loss on the Spin Forge sale, we recorded an
          impairment loss of $1,015,000 ($619,000, net of tax) in our December
          31, 2004 financial statements based upon the difference between the
          current carrying value of the equipment and its estimated fair value,
          calculated as the present value of the future minimum equipment lease
          payments from Aerojet plus estimated liquidation proceeds at the end
          of the minimum lease term. In conclusion, we believe that the Spin
          Forge operating business rather than the manufacturing equipment and
          tooling constitutes the long-lived asset or disposal group. Since DMC
          has no continued involvement in the operations of the Spin Forge
          business beyond the leasing of equipment and tooling and the sublease
          of the real estate, we are of the opinion that the sale of the
          disposal group occurred on September 17, 2004 and that all the above
          criteria have been met.

          Even after a "component of an entity" has been disposed of or has met
          the "held for sale" criteria, both of the following two criteria must
          be met in order to qualify as a discontinued operation:

               1.   The operations and cash flows of the "component of an
                    entity" have been (or will be) eliminated from the ongoing
                    operations of the entity as a result of the disposal
                    transaction.
               2.   The entity will not have any significant continuing
                    involvement in the operations of the component after the
                    disposal transaction.

          With respect to the first criteria, we believe that the operations and
          cash flows of Spin Forge have been eliminated from the ongoing
          operations of the Company.





          All operating activities of Spin Forge are the responsibility of
          Aerojet, including all costs and expenses relating to the Equipment
          Lease and the real estate sublease. The sublease rental income is
          equal to the rent that the Company pays the landlord under the primary
          lease and, as discussed above, the Equipment Lease is considered to be
          seller financing of the divestiture transaction. With respect to the
          second criteria, DMC's only continuing involvement in the Spin Forge
          business relates to the real estate sublease and the equipment
          financing transaction. The Company clearly has no control over the
          ongoing operations of the disposal group (the Spin Forge operating
          business) subsequent to the closing of the divestiture transaction on
          September 17, 2004. Based upon the foregoing considerations, we
          believe that both of the above criteria for reporting the Spin Forge
          divestiture as "discontinued operations" have been met.

                                      * * *

          We hope that our responses adequately address the questions that you
          raised in your May 4, 2005 comment letter. Please let us know if you
          require additional clarification with respect to our responses or have
          any additional questions.

          Sincerely,
