Abstract
The sintered sliding material according to the present invention consists of from 0.1 to 10% by of graphite, from 1 to 7% by of alumina, and balance of copper, and occasionally at least one member selected from the group consisting of from 1 to 10% of Sn and from 1 to 30% of Pb, and/or not more than 1% of P, and includes the alumina dispersed in the copper matrix. The alumina is held by the copper matrix so that the particles of alumina are not separated from the material during sliding under a boundary lubricating condition.
