Electrical contact material


PURPOSE:To obtain an electrical contact material having stable contact resistance and much superior welding resistance by internally oxidizing an alloy material having a specified composition consisting of Cd, Te, Bi and the balance Ag. CONSTITUTION:This electrical contact material is obtd. by internally oxidizing an alloy material having a composition consisting of, by weight, 10-20% Cd, 1-5% Te, 0.1-3% Bi and the balance Ag. The composition may further contain 0.1-0.5% Fe group element. This contact material is provided with the stable contact resistance of an Ag-CdO type electrical contact material and considerably improved welding resistance.
