Abstract
The invention relates to aluminum-tin (Al-Sn) base bearing alloys and bearing materials made by applying said alloys to a backing steel sheet by pressure welding. In an alloy according to the invention the coarsening of tin particles and the lowering of the hardness under high temperature conditions may be kept relatively moderate so that the wear resistance as well as the fatigue strength of the alloy are improved. Bearing alloys according to the invention may be used for the bearings of internal combustion engines in which spheroidal (nodular) graphite cast iron is generally used for crankshafts.
