PURPOSE:To obtain a sliding contact material with improved wear resistance by adding specified percentages of In and Te or the like to an alloy material consisting of specified percentages of Au, Ag and Cu. CONSTITUTION:A sliding contact material is manufactured by adding, by weight, 1-10% In and 0.5-3% at least one among Te, Ti, Li and Mg to an alloy material consisting of 61.5-63.5% Au, 6.5-8.5% Ag and 29-31% Cu without changing the ratio in the composition. Furthermore 0.01-0.5% Fe group metal may be added. The sliding contact material gives a brush contact which produces little powder owing to wear, has low and stable contact resistance, and hardly generates noise. |
