Abstract
A wear-resistant copper alloy containing 1.2 to 8.5% Mn, 0.3 to 2.5% Si, 3.0 to 8.0% Al, 20 to 40% Zn, 0.05% to 1.5% Te, and the balance of Cu and unavoidable impurities. The alloy includes other variations based on by adding (1) 0.5 to 3% Ni, (2) 0.5 to 13% Pb, (3) 0.5 to 3% Ni and 0.5 to 13% Pb or (4) 0.5 to 13% Pb and 0.02 to 1.5% Mg. Lead provides the self-lubricating property to the alloy. Magnesium disperses lead finely and uniformly in the alloy.
