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. C19210 has a nominal copper content of 99.9%. It is not heat-treat hardenable but it can be hardened by cold work. Its electrical conductivity is 80% IACS @ 68 F and it has good heat resistant characteristics.
