Abstract
Novel Ag-SnO electrical contact materials are disclosed, which are made of Ag alloys consisting of 5-20 weight % of Sn and a balance of Ag, the alloys having been prepared by melting and having been internal oxidized. Novel manufacturing methods are also disclosed, in which internal-oxidation is conducted in an oxygen atmosphere of 10 atm to 200 atm, and at a temperature of 750.degree. C. to 500.degree. C.
