PURPOSE:To improve the welding resistance and wear resistance of an Au-Pt- Pd-Ag type sliding contact material during sliding by adding specified elements 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 0.5-10% at least one among W, V and Ta without changing the ratio in the composition. 0.01-0.5% Fe group metal such as Fe, Ni or Co may be added furthermore. By adding at least one among W, V and Ta, the softening temp. is increased, and the welding resistance during sliding is improved. By adding the Fe group metal, the grains are made fine to improve the wear resistance. |
