ABSTRACT:
A sliding material has a sintered layer formed atop a backing plate. The sintered layer contains 5-15 mass % of Bi nonuniformly distributed in a Cu—Sn alloy matrix consisting essentially of 8-12 mass % of Sn and a remainder of Cu. The sliding material can be manufactured by nonuniformly mixing Cu—Sn alloy powder and Bi powder, dispersing the mixed powder on a backing plate, and sintering the mixed powder to form a sintered layer on the backing plate. The sliding material does not undergo seizing and does not have separation of the sintered layer from the backing plate even when used in severe conditions such as in hydraulic equipment or construction equipment.
