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. C92800 is a cast bronze containing nominally 16% tin and 5% lead. Former commercial names (not recommended) are (1) 295, (2) Leaded Tin Bronze, (3) Ring Metal and (4) 79-16-5-0. It has excellent machinability, moderate strength and good resistance to corrosion.
