Patent ID: 7041387

Claim:
A multi-layered aluminum-base bearing comprising a steel back layer, an intermediate aluminum alloy layer and an aluminum-base bearing alloy layer which contains one or more elements selected from the group of Cu, Zn, Mg and Si, and which is bonded to the steel back layer via the intermediate aluminum alloy layer, and the multi-layered aluminum-base bearing being subjected to solution treatment at a temperature of not lower than 400° C., wherein the intermediate aluminum alloy layer comprises a sub-layer being in direct contact with the steel back layer, and at least one sub-layer positioned closer than the former sub-layer to the aluminum-base bearing alloy layer, the former sub-layer consisting of an aluminum alloy comprising 2 to 8 mass % Si, and having a thickness proportion of 5 to 25% to the entire thickness of the intermediate aluminum alloy layer.
