Abstract

An aluminum base bearing alloy having outstanding seizure resistance, fatigue resistance and wear resistance and having particular utility as a thrust bearing, is provided. The alloy comprises, in addition to aluminum, 0.5-5 wt. % Si contained in the alloy in the form of at least 5 nodular Si particles having a diameter of at least 5 .mu.m per 9.56.times.10.sup.-2 (mm).sup.2 of cross-sectional area of the alloy. The bearing alloy may optionally contain at least one additional element selected from Cu, Mg, Mn and Cr. A bearing material is provided by pressure welding the aluminum base bearing alloy to a backing steel sheet.
