The mechanical properties and wear resistance in the oil lubricated condition for alloys Zn25%AlX%Cu were studied. It was found that with increasing of the copper content ultimate tensile strength of alloys gradually increased up to the maximum value 369 MPa with the copper content 6.64% while the elongation of the alloy Zn25%Al2.24%Cu had the maximum value 14.1% with 2.24%Cu. The elongation of alloys decreased in an excess above 2.24% copper. The hardness change of alloys was opposed to the elongation variation and the hardness of the alloy Zn25%Al2.24%Cu had the minimum value （HB98）. No εphase appear in interdendrite zones of the alloy Zn25%Al0.62%Cu

but εphases appeared in interdendrite zones of the alloy Zn25%Al2.24%Cu and increased with increasing of the copper content. With increasing of the copper content the wear resistance of alloys gradually increased.
