ABSTRACT:
There is presented an electrical contact material consisting of an alloy of gold and a compound selected from a group consisting of a carbide, a boride, or a silicide of a refractory element. The compound of the refractory element is selected from a group consisting of WC, Hfb.sub.2, TiB.sub.2, ZrB.sub.2, WSi.sub.2, and TiSi.sub.2. The resulting alloys have a hexagonal crystal structure and exhibit high wear resistance, low contact resistance, low electrical noise, and a homogeneous uncontaminated microstructure.
