Aluminum A612 is a natural aging aluminum alloy that develops high mechanical properties without a quenching heat treatment. It has high shock resistance and excellent corrosion resistance. It is recommended for highly stressed castings. This datasheet provides information on composition, physical properties, hardness, tensile properties, and compressive and shear strength as well as fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Al-144. Producer or source: Aluminum Company of America.
