Abstract

PURPOSE: To obtain a composite electrical contact material with superior melt- sticking resistance by internally oxidizing an Ag alloy contg. a specified amount of Cd and Hg or further contg. one kind or more among the Fe group elements.
CONSTITUTION: An Ag alloy contg. 0.5W20wt.% Cd and 0.5W5wt.% Hg or further contg. 0.01W2wt.% at least one kind of the Fe group elements such as Fe, Co and Ni is formed into ≤1mmϕ fine grains, and the grains are internally oxidized in an oxygen atmosphere at high temp. and pressure to prepare compoaite powder of silver-cadmium oxide-mercury oxide- (iron oxide, cobalt oxide or nickel oxide). This powder is then subjected to compression, sintering, extrusion and drawing, and the resulting wire rod is riveted to manufacture electrical contacts.
