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 No. 150 contains nominally 0.15% zirconium. It retains high conductivity with good hardness, strength and ductility at elevated temperatures. Applications include collector rings, bearings and current-carrying shafts.
