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. 182 is an age-hardening type of alloy that combines relatively high electrical conductivity with good strength and hardness. It was formerly known as Chromium Copper and its applications include such uses as resistance-welding-machine electrodes, switch contacts and cable connectors.
