    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 Fe3P, Fe2P, FeB, NiB and AlN, having an average particle diameter of 1.5 to 70 μm is contained.

    摘要: When a Cu—Sn—Bi had-particle based sliding material is used for sliding, Cu of Cu matrix flows and covers up Bi phase. Seizure resistance lowers as time passes. A Pb-free sliding material preventing the reduction of seizure resistance is provided. (1) Composition: from 1 to 15% of Sn, from 1 to 15% of Bi, from 0.02 to 0.2% of P, and from 1 to 10% of hard particles having an average diameter of from 50 to 70 μm, with the balance being Cu and unavoidable impurities. (2) Structure: Bi phase and the hard particles are dispersed in the copper matrix, and all of said hard particles are bonded to the copper matrix.
