This specification covers an aluminum alloy in the form of bars and rods 0.500 in. (12.70 mm) and over in nominal diameter or least distance between parallel sides.
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).
This specification covers an aluminum alloy in the form of hand forgings procured to metric dimensions. AMS 4323 is the inch/pound version of this MAM. These forgings have been used typically for parts requiring a high level of mechanical properties and good resistance to stress-corrosion cracking, but usage is not limited to such applications.
