Overview
Technical Parameter
A product made of CuPb24Sn4 material sintered on the surface of a steel plate as the substrate. This product has good fatigue strength and load-bearing capacity. Suitable for medium speed and medium load applications with oil lubrication, when surface coated with soft alloy, it can be used as high-speed internal combustion engine bearings and connecting rod bushings to achieve good wear resistance and fatigue resistance.
