Abstract:
1. A plain bearing composite material comprising a metal supporting layer, an intermediate layer of an aluminium alloy and a bearing layer of an aluminium alloy, wherein the alloy components of the aluminium alloys of the intermediate layer and the bearing layer are the same apart from an additional soft phase fraction in the bearing layer, and where the quantities of the alloy components of the aluminium alloy of the intermediate layer and the aluminium alloy of the bearing layer are the same apart from the additional soft phase fraction in the bearing layer; and wherein the aluminium alloys of the intermediate and bearing layer include 1.0-3 wt. % nickel, 0.5-2.5 wt. % manganese 0.02-1.5 wt. % copper, the remainder being aluminium allowing for impurities, and wherein the aluminium alloy of the bearing layer additionally has the soft phase fraction.
