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. C41500 is a copper-zinc-tin alloy with good strength and good ductility. It can be cold worked readily by conventional processes. It has excellent performance in brazing and soldering; it can be welded by several processes. A typical use is springs for electrical switches.
