Zusammenfassung:The sintered electrical contact material described in this specification includes at least one salt dispersed within a silver matrix, and no more than 100 ppm of cadmium and cadmium compounds. The sintered electrical contact material exhibit contact resistances much lower than than commercially available silver composites. The salts dispersed within the silver matrix represent a new class of additives for silver composites for high and low current applications.
