Effects of Cu addition on the mechanical properties of Al-16vol%Pb-3vol%Mg alloys, and also on friction and wear properties were investigated. A ring-on-block type Ogoshi wear test and a pin-plate type test were conducted in air to study the dry sliding behavior of Al-Pb-Mg-Cu alloys against high carbon chromium bearing steel(SUJ2). The wear characteristics were compared with that of leaded bronze(LBC4). The result obtained were summarized as follows:<BR>(1) The mechanical properties depend on Cu content and porosity. A maximum bending strength of 120Mpa was obtained at 3vol%Cu content.<BR>(2) The wear ratio against hard steel(SUJ2) is almost independent of Cu content.<BR>(3) The wear ratio of alloys with 0-6vol%Cu against SUJ2 is less worn than the currently used LBC4.<BR>(4) The wear ratio of the alloys decreases with increasing applied load.
