Abstract of Disclosure Internally oxidized Ag-Sn-Bi alloy electrical contact materials. The alloy contains a large amount Or Bi, viz., more than 1 weight percent of bismuth, whereby the Bi which can not be a solid solution with Ag and Sn and hence pre- cipitates as a numerous number of defects in an Ag matrix, does not allow said Ag matrix to form crystalline grains, but accelerates oxidation velocity and has solute metals oxidized extremely in minute and uniform up to inner cores of alloy mass.
