ABSTRACT:
A multi-layer metal bearing for use in a large-size engine or the like has three layers including a steel backing layer, a bonding or an intermediate layer of aluminum or aluminum alloy, and a bearing alloy layer consisting of more than 50% up to 65% by weight of tin, more than 0.5% up to 1.5% by weight of copper, and the remainder being essentially aluminum. The hardness of this bearing alloy at a relatively high temperature such as 100.degree. C. or higher is in the mid-range between that of the convention Al/Sn bearing alloy having 50% by weight or less of tin and that of the conventional white metal bearing alloy. This multi-layer metal bearing for use in a large-size engine presents a remarkably improved resistances against load and fatigue.
