A bearing metal for large size engines having excellent compatibility and as well as embeddability even when used under a poorly lubricated condition. Such bearing metal consists of three or four layers, including a layer of a bearing alloy which contains more than 50% and up to 65% by weight of tin, with the remainder being made up of aluminum, and which may also include less than 0.5% by weight of copper. This bearing alloy has a hardness at high temperature exceeding 100 DEG C. lying between that of aluminum-tin bearing alloys which contain up to 50% by weight of tin and that of tin base or lead base white metal bearing alloys. |
