Abstract (en)
A silver-oxide based material for electric contacts, which has excellent deposition resistance and consumption resistance. The material is formed by subjecting to an internal oxidation treatment an Ag based alloy consisting essentially of: Sn: 4 - 11%; In: 1 - 5%; Te: 0.05 - 4%; and Ag and inevitable impurities: the balance. If required, at least one of the following elements may be added: (a) at least one element selected from the group consisting of Fe, Ni, and Co: 0.01 - 1%; and (b) Cd: 0.05 - 3%.
