AMS-C-26074 on Electroless Nickel Coatings has been cancelled

AMS-C-26074 Cancellation Revision C has just been issued.  Titled “Electroless Nickel Coatings,” the specification covers the requirements for electroless (autocatalytic chemical reduction) deposition of nickel-phosphorous alloy coatings on metal and composite surfaces.

The document replaced MIL-C-26074 for all users except for NAVSEA Nuclear personnel.  With this cancellation, users are directed to AMS-2404 for replacement purposes and AMS-2404 or AMS-2433 for new design.  The table on the first page of the cancellation revision lists the correlation information to match the classes and grades of AMS-C-26074 with AMS-2404.

As we blogged about before, the AMS-C-26074 was generated to replace MIL-C-26074 and was taken directly from the source document.  After the release of AMS-C-26074 Revision A, the specification was cancelled in favor of the reinstated MIL-C-26074 Revision E.  The mil spec was then replaced by MIL-DTL-26074 Revision F which is a controlled distribution document for NAVSEA use only.  So the AMS-C-26074 was reinstated as a replacement for the balance of users with the release of Revision B.

Since that time, AMS-2404 has been updated to resolve issues of technical equivalency.  So at last the AMS-C-26074 has been put to bed!

Both the current and obsolete AMS documents are available from Document Center Inc., as well as the MIL Specs (with the exception of controlled distribution documents).  Order the current editions directly on our website ( or ask for a quote on the obsolete revisions.  That way, we’ll be able to confirm that you recognize obsolete documents are no longer valid and provide you with pricing as well.   Or feel free to contact us by phone (650-591-7600), fax (650-591-7617) or email (
