A silver-metal oxides alloy electrical contact material that is highly resistant to sticking and arc-wear is disclosed. The contact material is made by internally oxidizing an alloy consisting essentially of 3-9 wt % Sn, 1-3 wt % In, 0.2-3.0 wt % Cd, 0.05-1 wt % Ni, 0.3-0.8 wt % Cu, the balance being Ag and incidental impurities.
