This specification covers an aluminum alloy in the form of bars and rods 0.500 inch (12.7 mm) to 8.000 inches (203.2 mm) in nominal diameter or least difference between parallel sides and up to 50 square inches (322.6 square centimeters) in cross-sectional area (see 8.7).
The results of this test are intended to be a useful indication of the resistance to distortion of bare or two-side Alclad, flat sheet aluminum used in chemical milling applications.
This specification covers an aluminum alloy in the form of bars and rods 0.375 to 0.874 inch (9.52 to 22.20 mm) in nominal diameter or least distance between parallel sides.
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.
