Copper Alloy No. C82500 is an age-hardenable copper-base casting alloy containing nominally 2% beryllium. It offers high strength, toughness and good resistance to corrosion. It has good fatigue strength in the age-hardened condition. Typical uses include bushings, bearings, valves, cams and safety tools. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-512. Producer or source: Copper alloy foundries.
