Abstract
An aluminum base bearing alloy having outstanding seizure resistance, fatigue resistance and wear resistance is provided. The alloy comprises, in addition to aluminum, 0.5-5 wt. % Si and 1.5-35 wt. % Sn and contains at least 5 nodular Si particles having a diameter of at least 5 .mu.m per 3.56.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 Pb, In, Tl, Cd, Bi, Cu, Mg, Cr and Mn. A bearing material is provided by pressure welding the aluminum base bearing alloy to a backing steel sheet.
