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 No. 803 is cast copper containing silver to raise its softening temperature and improve its elevated-temperature properties. It has low room-temperature strength with medium-to-good ductility. It is characterized by a good combination of thermal and electrical conductivity and is resistant to corrosion. These characteristics make it highly suitable for many applications requiring good conductivity and/or corrosion resistance.
