Abstract
The invention provides a coated Cu alloy and a process for producing the coated Cu alloy having a surface which has a low coefficient of friction and a high resistance to abrasion and is suitable for fabricating connectors, charging-sockets of electric automobiles etc. The coated Cu alloy is produced by coating the surface of a copper alloy with Sn and heat treating the coated Cu alloy at a temperature in the range of 100-450.degree. C. for 0.5-24 hours. The Cu alloy which is coated with Sn consists of 1-41 wt % Zn with the balance being Cu and incidental impurities. By using the coated Cu alloy, the force of insertion, resistance to abrasion and resistance to corrosion of connectors can be significantly improved.
