In order to make the wear-resistance and machinability of the copper-based sliding material, in which such particles as AlN, Al2O3, NiB, Fe2B, SiC, TiC, WC, Si3N4, Fe3P, Fe2P and/or Fe3B are dispersed in the matrix consisting of sintered Cu or Cu alloy, the dispersion is performed such that the weight proportion and the average particle diameter of the medium-hardness particles of Hv 500 or more and 1000 or less are greater than those of the high-hardness particles having Hv 1100 or more. |
