View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.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.
