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. C93500 is a cast bronze containing nominally 9% lead and 5% tin. It has excellent machinability, low strength and good resistance to corrosion. It is used for corrosion-resistant castings, small bearings and bushings.
