ABSTRACT:
A silver base electrical contact material is described which contains a dispersion of particles consisting of cadmium oxide and nickel. The nickel particles are surrounded by a continuous adherent coating of nickel oxide which eliminates the detrimental reaction which would otherwise occur between nickel and cadmium oxide. The invention contact materials have improved lives and are fabricated by any one of several different powder metallurgy techniques.
