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.Chromium Copper-182 is a copper-chromium corrosion resistant alloy which is softened by a high-temperature solution anneal and quench, and will improved acquire properties with a low temperature precipitation-hardening heat treatment.
