PURPOSE:To improve the wear resistance of the resulting sliding contact material by adding small amounts of Sb and one or more among Si, Bi, Ge and Ga 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% Sb and 0.1-3% one or more among Si, Bi, Ge and Ga 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. |
