ABSTRACT:
Electrical contact materials made from an internally oxidized Ag alloy containing 0.5 to 12 weight % of Sn. Internal oxidized structures which have been produced in the alloy at the forwardmost area along a progressive direction of internal oxidation and which are fine and free from the segregation of tin oxides, are employed as contact surfaces. Another surface opposite to said contact surfaces may be brazeable by having it subjected to a reduction or decomposition treatment of metal oxides about said another surface.
