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. C94500 is a cast bronze containing nominally 73% copper, 20% lead and 7% tin. It has excellent machinability, good casting characteristics, low strength and good resistance to corrosion. It is used for bearings, locomotive wearing parts and for corrosion-resistant castings.
