Abstract

An aluminum-based bearing alloy of the invention comprises 3-40% Sn, 0.1-10% Pb, 0.1-5% Cu, 0.1-3% Sb, total 0.05-1% of Ti and B which satisfy the equation: B/Ti+B=0.1 to 0.35, and the balance being essentially Al. The aluminum-based bearing alloy according to the present invention has excellent fatigue resistance and anti-seizure property.
