Abstract

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.

Make brush wire rods, cut each into 8 mm length, and
These are placed in parallel and one end is 4mm long, 13fi long, and 0 thick.
．． A brush contact was made by welding to the 2-tsuru material and bending a 2R arc-shaped contact portion at the other end. Then, each brush contact was brought into contact with a disk-shaped commutator, and the commutator was rotated in forward and reverse directions to perform a sliding test under the following test conditions, and the wear amount and contact resistance were measured. The results shown in the column were obtained.
