Abstract
A multi-layered bearing having superior load-resistance comprises an aluminium base bearing alloy layer and a backing metal layer. The bearing alloy consists essentially of, by weight, 2-8% zinc, 0.1-8% silicon, 0.1-3% copper, 0.05-3% magnesium and the balance of aluminium. The bearing alloy is subjected to a solution treatment and an artificial aging treatment, and it has a hardness of Hv 70 or greater. The bearing alloy may contain at least one element selected from the following five elements of lead, manganese, vanadium, chromium and nickel, and may further contain strontium and/or titanium and boron. The hardness of the bearing alloy may be Hv 70 or higher by performing solution treatment on a bimetal at a temperature of 400.degree. C. or higher before the plastic working, and further by performing an artificial aging treatment thereon at a temperature of 250.degree. C. or lower.
