The new AMS-A-22771 Revision C has just been released and it’s available now from Document Center Inc. The standard, “Aluminum Alloy Forgings, Heat Treated,” is one of the primary plating specifications in general use, but it is valid only for replacement purposes, not for new design.
This specification covers the requirements for heat treated aluminum alloy die forgings, hand forgings, and ring forgings, produced under additional mechanical property control to ensure known mechanical properties for parts used in aerospace critical applications. AMS-A-22771C also covers the requirements for forgings furnished in the F or 01 conditions which will ultimately be used in the heat treated condition.
The initial SAE publication of this document was taken directly from the now obsolete U.S. Military Specification MIL-A-22771D. It retains the same part numbers established by the original military document, but requirements relating to the QPL (Qualified Products List) are not part of the SAE document.
All current SAE standards and many obsolete editions are available from Document Center Inc. in either pdf or paper format. Order using our website, www.document-center.com.
