ABSTRACT:
The present invention is related to a brake lining material for a heavy-load braking device. The present invention is to provide a novel brake lining material which can have extended useful life under heavy-load conditions, can retain stable coefficients of friction under such heavy load conditions, can have appropriate wear resistance and can reduce the wear of its opponent material significantly. In accordance with the present invention,the novel brake lining material is provided which comprises copper-base metal powder, refractory material powder and graphite powder, the metal powder containing iron powder and titanium powder and being used as a matrix, the refractory material powder and the graphite powder being sintered together with this matrix in a uniformly distributed state in the powder. For example, a brake lining material for a heavy-load braking device is provided, which comprises, on a base of its total weight, 10 to 20 % refractory material powder, 15 to 25 % graphite powder and, as the remainder, copper-base metal powder, in which the refractory material powder are sintered together with the copper-base metal powder in a uniformly distributed state in the powder.
