摘要

A silver-coated stainless steel strip for movable contacts, which has an underlying layer comprising any one of nickel, cobalt, nickel alloys, and cobalt alloys, on at least a part of the surface of a stainless steel substrate, and has a silver or silver alloy layer formed as an upper layer, in which a copper or copper alloy layer with a thickness of 0.05 to 2.0 µm is provided between the silver or silver alloy layer and the underlying layer; and a producing method of the above-described silver-coated stainless steel strip, in which said strip is subjected to a heat-treating in a non-oxidative atmosphere.
