Abstract: Disclosed is a sliding material containing 0.5 to 15 mass % of Sn, 0.2 to 10 mass % of Ni, 0.4 to 10 volume % of hard particles, and the balance being essentially Cu. The hard particles are of one or more selected from the group consisting of WC, W2C, Mo2C, W, and Mo. A grain size of the CunullSnnullNi matrix is set to be not more than 0.070 mm.

Abstract: A copper-based sliding material produced by sintering, comprising at least two phases of copper and/or copper alloys which phases have hardness levels different form each other, and hard particles with an average particle size of 0.1 to 10 nullm which are dispersed in at least one phase with the exception of a softest phase in an amount of 0.1 to 10 vol.% of the whole copper-based sliding material, said sliding material satisfying (H2/H1)null1.2 in which H1 is the Vickers hardness of the softest phase and in which H2 is the Vickers hardness of a phase hardest in hardness including said hard particles.
