Composite material for plain bearing elements of a type having a metallic backing and an overlay of aluminum-based bearing material applied on the back. The bearing material is a heterogeneous aluminum alloy having a matrix containing in addition to aluminum, nickel, manganese, and copper. There is dispersed within the matrix, segregated tin or segregated lead, in an amount of from 0.5% to 20% by weight in the case of tin. The matrix contains hard particles of nickel, manganese, nickel-manganese, and alloys of nickel-manganese, and are located in the bonding regions between the matrix and the segregated tin or segregated lead. The segregated tin or segregated lead deposits are substantially free of hard particles. The hard particles are substantially of a dimension .ltoreq.5 um. and are present in a quantity of less than 5 hard particles of a dimension .gtoreq.5 um. in a cube-shaped volume element, the edge of which is 0.1 mm. long.

In a laminate for friction bearing elements which contains, on a metallic support layer, an anti-friction layer comprising an aluminum alloy containing nickel, manganese and lead, there is additionally provided bismuth or copper which improve considerably the bearing properties and also facilitate the surface machining by chip removal of the anti-friction layer. It is of particular advantage if the aluminum alloy has the addition of both bismuth and copper, resulting in considerably improved sliding characteristics and improved emergency running properties in addition to substantially improved properties regarding strength, dynamic loadability, fatigue strength and good machinability.
