Characteristic
CuSn8 is a solid solution strengthened copper alloy (bronze) with 8% tin. The high tin content results in high strength and good spring properties at an adequate conductivity. The alloy is wear-resistant, has very good corrosion resistance and can be readily soldered. Moreover CuSn8 has good sliding properties. Fields of application are stamped parts, connectors, spring contacts, springs, bushings and bearings, metal hose, the paper industry, ship and apparatus manufacturing as well as electrical and mechanical engineering.
