A composite sliding structure has a surface layer, a bond layer bonded to the surface layer, an intermediate layer bonded to the bond layer and a backing layer bonded to the intermediate layer. The surface layer is an alloy consisting essentially of 0.1-6.0% Cu and the balance Pb, an alloy consisting essentially of 0.1-6.0% Cu, 0.5-16.0% In and the balance Pb, an alloy consisting essentially of 0.5-16% In and the balance Pb, or any one of these alloys also containing 4% or less Sn. The bond layer is Cu, an alloy consisting essentially of 0.5-20.0% Zn and the balance Cu, an alloy consisting essentially of 0.1-4.0% Sn and the balance Cu, Ni, an alloy consisting essentially of 0.5-20.0% Zn and the balance Ni, or an alloy consisting essentially of 0.1-4% Sn and the balance Ni. The intermediate layer is Al, an alloy consisting essentially of 1.0-13.0% Si, 1.5-6.0% Zn and the balance Al, an alloy consisting essentially of 1.5-13.0% Si and the balance Al, an alloy consisting essentially of 0.1-4.0% Sn and the balance Al, or one of these alloys also containing, as additive, one or more elements selected from the group consisting of Cu, Mn, Cr, Zr, V, Pb and Sb by 4.0% or less. The backing metal layer is made of hard support material. |
