Product Code:SAE AMSQQA250/22
Title:Aluminum Alloy, 7178-T76, Alclad Plate and Sheet, Improved Exfoliation Resistant (NONCURRENT Mar 2007)
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope: This specification covers the specific requirements for improved exfoliation resistant alclad aluminum alloy 7178-T76 sheet and -T7651plate. The general requirements are covered in AMS-QQ-A-250. The plate and sheet covered by this specification shall be an integral composite product consisting of a heat-treatable aluminum alloy (7178) core with thin layers of an aluminum alloy (7072) anodix to the core and of approximately equal thickness, bonded to both surfaces.
