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. C93800 is a cast copper-tin-lead alloy (bronze). It is characterized by low strength, good machinability and good resistance to corrosion. Commercial names formerly used (not recommended) are (1) Anti-Acid Metal, (2) Ingot No. 319, (3) High-Leaded Tin Bronze and (4) 78-7-15. Its many applications include bearings, bushings, pump impellers and corrosion-resistant castings.
