Abstract (en)
Electrical contact materials are made of internally oxidized Ag-Sn Solid-Solution type alloys of 5-20 weight % Sn, added by a trace amount of more than 0.1 weight % to less than 1 weight % of In. Such addition of In is effective to have Sn oxides precipitated not too finely in said Ag-Sn alloys, whereby their electrical characteristics, especially electrical contact resistances thereof are improved, and subsequently their temperature rising is held low.
