【Abstract】 A new contactor material made of Ag-Sn-Ce alloy with a small amount of rare earth elements is studied and produced by smelting, casting and pressure working, which has excellent abilities of inhibit sweating and quenching and lower abrasive wear and temperature rise. The applications to snap-action switchs and long lifetime relays show that this material can meet with the technological standards. Its contact electroproperties are better than other silver based alloys. It can be used to replace the Ag-CdO alloy and other gold-based alloys.更多还原
