Beschreibung
Zusammenfassung:	A palladium-base alloy as contact material consists of Pd 30-85 wt%, Cu 14-70 wt% and RE (one of La, Ce, Sm and Gd) 0.05-1 wt%. Palladium-base composite contactor is prepared by compounding the palladium-base alloy of the present invention and copper alloy-base material, which comprises Cu 84-98.4 wt%, Fe 0.5-5 wt%, Ag 1-10 wt% and RE (one of La, CE, Sm and Gd) 0.1-10 wt%. The alloy material of the present invention is prepared through conventional casting and heat treatment process. the palladium-base alloy may be produced into wire, belt, pure alloy contact or composite alloy contact as required.
