Abstract
Disclosed is a multi-layered Al-base bearing consisting of a steel back layer, an intermediate Al alloy layer and an Al-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 Al alloy layer. The bearing is subjected to solution treatment at a temperature of not lower than 400° C. The intermediate Al alloy layer has 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 Al-base bearing alloy layer. The former sub-layer consists of an Al alloy contains 2 to 8 mass % Si, and has a thickness proportion of 5 to 25% to the entire thickness of the intermediate Al alloy layer.
