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. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, joining, and surface treatment. Filing Code: Cu-370. Producer or source: Copper alloy foundries.
