Resistac No. 1 is a high strength, corrosion resistant aluminum bronze capable of responding to heat treatment for increased strength and hardness. It has exceptionally good fatigue resisting qualities and will retain its strength and hardness at relatively high temperatures. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, and joining. Filing Code: Cu-2. Producer or source: American Manganese Bronze Company.
