PURPOSE:To obtain a sliding contact material with improved wear resistance anc contact resistance characteristics by adding a specified amount of at least one among Co, Sn and Ti to an alloy material consisting of specified percentages of Au, Pt, Ag, Cu and Zn to increase the softening temp. CONSTITUTION:To an alloy material consisting of, by weight, 70.5-72.5% Au, 7.5-9.5% Pt, 3.5-5.5% Ag, 13.5-15.5% Cu and 0.5-1.5% Zn is added 0.5- 15wt% at least one among Co, Sn and Ti without changing the ratio in the composition. A brush contact having superior wear resistance, producing little powder owing to wear, and generating hardly any noise is obtd. The brush contact has stable contact resistance. |
