    摘要: A silver-oxide material for electric contacts of high-current switches, having excellent deposition resistance and consumption resistance. The material is formed by subjecting to an internal oxidation treatment an Ag alloy consisting essentially, by weight %, of:Sn: 5.1-8.5%;In: 1.7-3.2%;Te: 0.1-0.6%; andAg and inevitable impurities: the balance. If required, at least one of the following elements may be added:Ni: 0.05-0.2%; andCd: 0.3-0.8%.
