Aluminum Alloy, 7011 Alclad 7178 Plate and Sheet
This specification covers the specific requirements for 7178 aluminum alloy, 7011 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 7178 aluminum alloy core with thin layers of a 7011 aluminum alloy anodic to the core and of approximately equal thickness, bonded to both surfaces.
AMS-QQ-A-250/28C has been designated stabilized because alloy 7178 is not recommended for new designs.
