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. C84200 is a free-cutting copper-zinc-tin-lead alloy. It is characterized by good casting properties, moderate strength and ductility, good machinability and good resistance to corrosion. Formerly used named (not recommended) are 101, Leaded Semi-Red Brass and 80-5-2.5-12.5. Typical applications are pipe fittings, bushings, locknuts and unions.
