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. C43000 is a copper-zinc-tin alloy of moderate strength and ductility. It can be hot worked readily. It has excellent cold-working characteristics and can be fabricated by the conventional cold-working processes. It is used for fuse and pen clips, weather stripping, electrical switches and springs.
