PURPOSE:To increase the softening temp. of an Au-Pt-Pd-Ag type sliding contact material and to improve the welding resistance during sliding by adding a specified element to the contact material. CONSTITUTION:To an alloy consisting of 19-21% Au, 4-6% Pt, 44-46% Pd and 29-31% Ag as a sliding contact material, especially as a brush contact material is added 0.5-15% at least one among Co, Sn and Ti without changing the ratio in the composition. The softening temp. of the sliding contact material is increased, the welding resistance during sliding is improved, and an oxide produced during sliding acts as a lubricant to improve the wear resistance. |
