     Re:  SIMCALA, Inc. -- Registration Statement on Form S-1 with respect to
          $75,000,000 9-5/8% Senior Notes due 2006, Series B

Gentlemen:

     We have acted as counsel to SIMCALA, Inc., a Delaware corporation (the
"Company"), in connection with the registration under the Securities Act of
1933, as amended, of $75,000,000 aggregate principal amount of 9-5/8% Senior
Notes due 2006, Series B (the "Exchange Notes"), pursuant to a Registration
Statement on Form S-1 (the "Registration Statement"). The Exchange Notes will
be issued pursuant to the terms of an Indenture by and between SAC Acquisition
Corp., a Georgia corporation ("SAC"), and IBJ Schroder Bank & Trust Company, as
trustee (the "Trustee"), and an Indenture Supplement by and between the Company
(as successor to SAC) and the Trustee, each dated as of March 31, 1998
(collectively, the "Indenture"), in exchange for the identical principal amount
of any and all of the Company's outstanding 9-5/8% Senior Notes due 2006,
Series A (the "Series A Notes").

     In connection with the foregoing, we have examined the Company's
Certificate of Incorporation and Bylaws, the corporate proceedings taken by the
Company to authorize the offering, sale and issuance of the Series A Notes and
the Exchange Notes, the Indenture (including the form of the Exchange Notes),
and the Registration Statement. We also have examined and relied upon such
other records, documents and other instruments in our judgement necessary or
appropriate in order to express the opinions hereinafter set forth.

     Based on the foregoing, we are of the opinion that the Exchange Notes have
been duly authorized and, when issued and exchanged for the Series A Notes in
accordance with the terms of the Exchange Offer described in the Prospectus
included in the Registration Statement, will be validly issued and binding
obligations of the Company.
