The purpose of the study is to show how friction and wear are affected by <i>θ</i> phase (CuAl<sub>2</sub>) in Al-Cu alloys. To achieve this purpose, six pieces of Al-Cu alloys with different <i>θ</i> phases were fabricated by an usual casting method and used for the tests as a disk specimen. Friction and wear tests were carried out using a pin on disk type machine under dry and lubricated friction conditions. The results obtained are as followsb ; In dry friction tests Al-Cu alloys containing 50 to 91% <i>θ</i> phase area fraction (Af) showed a low friction coefficient and superior characteristics in specific wear rate or seizure resistance when applied to G2-cemented carbide. Under the lubricated conditions, the effecis of the <i>θ</i> phase depended on the Af and PV values, that is, the friction coefficient and wear damage were the smallest for the alloy specimens containing 7 and 78% Af <i>θ</i> phases.
