Abstract
The sliding member of the invention comprises a steel backing and a sintered Cu-alloy layer mounted integrally on one surface of the backing metal, wherein the sintered Cu-alloy comprises 1 to 15% Sn, 1 to 20% Ni-B compound, 1% or less phosphorus, and the balance of Cu and impurities. Cu-alloy may further contain 1 to 30% Pb and/or 0.5 to 8% graphite. Pb and graphite provide the sliding alloy layer with good lubrication property. Preferably the Ni-B compound is used, which is composed of 7 to 15% B and the balance of Ni and impurities.
