A Cu-based wear-resistant alloy of a sliding material consists essentially of, by weight, 10-35% Zn, 2-20% Pb, 1-10% Ni, 0.1-1% B and, as required, 0.5-10% of Sn. The alloy can be used under severe conditions of use at elevated speed and temperature with reduced risk of seizure and corrosion. The alloy can be produced by mixing Pb powder and Ni--B alloy powder with Cu--Zn powder or Cu--Zn--Sn alloy powder, or mixing Ni--B alloy powder with Cu--Zn--Pb alloy powder or Cu--Zn--Sn--Pb alloy powder. The alloy can be compacted and sintered to form a sliding member or a composite sliding member is obtained by sintering and integrating the alloy on a steel backing plate optionally having a surface plated with copper.
A wear-resistant sliding layer having superior anti-seizure and corrosion properties formed of a sintered alloy consisting essentially of 10 to 35 wt % of zinc, 10 to 20 wt % of lead, 1 to 10 wt % of nickel, 0.1 to 1 wt % of boron, and balance copper and unavoidable impurities.
A sintered copper alloy of a sliding-contact material having superior properties of anti-seizure resistance, wear resistance and corrosion resistance consisting essentially of 10 to 35 wt % of zinc, 2 to 20 wt % of lead, 1 to 10 wt % Ni, 0.1 to 1 wt % B, with at least part of said Ni and B forming Ni--B compound, and balance of copper and unavoidable impurities.
