Product Code:SAE AMSQQA250/5
Title:Aluminum Alloy Alclad 2024, Plate and Sheet
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope: This specification covers the specific requirements for 2024 aluminum alloy alclad plate and sheet; 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 2024 core with thin layers of an aluminum alloy 1230 (99.30 percent minimum aluminum) anodic to the core and of approximately equal thickness, bonded to both surfaces.
