Abstract
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.
