Abstract: A sliding material of a single substance made by extruding powder comprises aluminum as a main constituent, and at least one metal compound of 0.5 to 30 wt. % in total selected from the group consisting of metal nitride, metal carbide, metal phosphide, and metal boride, each of which has a hardness not less than 200 in Vicker's hardness, the metal compound being uniformly and finely dispersed in aluminum.

Abstract: A composite material for a sliding member has a back metal layer and a graphite-containing phosphor bronze sintered layer bonded to the back metal layer. The graphite-containing phosphor bronze sintered layer consists essentially of 0.03 to 1 wt % phosphorus, 7.5 to 16 wt % tin, 1 to 8 wt % graphite and the balance copper, and is constituted by phosphor bronze powder passing through a 200-mesh screen and a graphite powder passing through a 350-mesh screen. Also disclosed is a method of manufacturing the above-mentioned composite material for a sliding member.

Abstract: This invention is an alloy for use as a bearing lining as an alternative to the known "white metals".The alloy is predominantly of tin, but includes from 0.001 to 0.5% by weight of chromium and from 0.005 to 0.5% by weight of cobalt.The micro-structure is good and the alloy can be bonded to a steel backing, and is strong and ductile.
