    摘要: [Task] In the provided Cu-based sliding material, the properties equivalent to those of a Pb-containing material is attained even free of Pb, and material has stable friction coefficient.
    [Solution Means] A Pb-free copper-alloy sliding material contains 1.0 to 15.0% of Sn, 0.5 to 15.0% of Bi and 0.05 to 5.0% of Ag, and Ag and Bi from an Ag-Bi eutectic. If necessary, at least one of 0.1 to 5.0% of Ni, 0.02 to 0.2% P, and 0.5 to 30.0% of Zn is contained. Further, if necessary, 1.0 to 10.0 mass % of at least one of a group consisting of Fe 3 P, Fe 2 P, FeB, NiB and AlN, having an average particle diameter of 1.5 to 70 µm is contained.
