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. 184 combines good strength and hardness with fairly high electrical and thermal conductivity. It is an age-hardening type of alloy that formerly was known as Chromium Copper. Its applications include structural parts, electrode holder jaws and various components for electrical and electronic devices.
