PURPOSE:To improve the wear resistance of the resulting sliding contact material by adding small amounts of Mn and >=1 kind among Si, Bi and Ge to an alloy material having a specified composition consisting of Au, Ag and Cu. CONSTITUTION:This sliding contact material is obtd. by adding, by weight, 1-10% Mn and 0.1-3% >=1 kind among Si, Bi and Ge to an alloy material consisting of 61.5-63.5% Au, 28-30% Ag and 7.5-9.5% Cu without changing the ratio in the composition. To the alloy material may be further added 0.01- 0.5% Fe group metal. This sliding contact material can give a brush contact which causes a smaller extent of wear than a brush contact made of a conventional sliding contact material and has comparably low and stable contact resistance. |
