摘要:
A multi-layer bearing having an Al--Sn bearing alloy layer which has high fatigue strength and good conformability with a mating member further comprising a backing steel plate and an intermediate bonding layer of another aluminum alloy. The Al--Sn alloy consists essentially of, by weight, 7 to 20% Sn and balance of Al and impurities, and has a hardness of Hv 50 to 80. The aluminum alloy of the intermediate bonding layer consists essentially of, by weight, at least one of up to 1.7% Mn, up to 1.2% Cu and up to 1.8% Mg, and balance of Al and impurities, and a hardness rate of the aluminum alloy of the intermediate bonding layer to the Al--Sn bearing alloy exceeds Hv 70% and is not greater than 90%.
