Exhibit 5

January 3, 1996

Aluminum Company of America
425 Sixth Avenue, Alcoa Building
Pittsburgh, PA  15219-1850

Ladies and Gentlemen:

You have requested my opinion as to the legality of the
interests in the Alcoa Fujikura Ltd. Hourly 401(k) Plan and
the Alcoa Fujikura Ltd. Salaried 401(k) Savings Plan (the
"Plans") and of the shares of common stock of Aluminum Company 
of America (the "Company") to be distributed pursuant to the 
Plans, which interests and shares of common stock you are 
seeking to register with the Securities and Exchange 
Commission under the provisions of the Securities Act of 1933, 
as amended.

As Assistant Secretary and Senior Counsel of the Company I am
generally familiar with its legal affairs.  In addition, I have
examined such documents as I have deemed appropriate for the
purpose of this opinion.

In my opinion:

     (1)  the Plans have been duly adopted by Alcoa Fujikura
Ltd.;

     (2)  the interests in the Plans if issued pursuant to the
provisions thereof will be legally issued;

     (3)  if shares of common stock of the Company heretofore 
issued shall be purchased in the open market by the Trustees 
under the Plans and distributed to the participants in the 
Plans pursuant to the provisions thereof, the said shares of 
common stock will be legally issued, validly outstanding, and 
fully paid and non-assessable; and

     (4)  if authorized but previously unissued shares of
common stock of the Company, the issuance of which to the 
Trustees in accordance with the provisions of the Plans at 
values not less than the par value of the shares shall have 
been authorized by the Board of Directors of the Company, 
shall be so issued, the purchase price therefor shall be duly 
paid to the Company and the said shares shall be distributed 
to the participants in the Plans pursuant to the provisions 
thereof, the said shares of common stock will be legally 
issued, validly outstanding, and fully paid and non-assessable.

I hereby consent to be named, in the registration statement,
and amendments thereto, by which the securities to be issued
pursuant to the Plans are registered with the Securities and
Exchange Commission, and in any prospectus relating to the
Plans, as counsel for the Company who has passed upon the
legality of the securities registered thereby.  I further
consent to the filing of this opinion as an exhibit to the
registration statement.  I do not concede by these consents
that I come within the category of persons whose consent is
required under Section 7 of the Securities Act of 1933, as
amended, or by the rules and regulations of the Securities
and Exchange Commission under that Act.

Very truly yours,
