Bimetal Bearings , Low Carbon Steel With Aluminum-Tin alloy ( AlSn20Cu )
AlSn20Cu Bimetal Bearings is backed with high quality low carbon steel with Aluminum-Tin alloy (AlSn20Cu) sintered on its surface. To effectively decrease abrasion, AlSn20Cu Bimetal Bearings' alloy surface can be machined with oil grooves for easier oil storage. When necessary, an erosion protection coating can be plated on the steel back. In common application, AlSn20Cu Bimetal Bearings is used to make wrapped bushes, thrust washer and bushes on connecting rod level of gas engine, etc.
