Development of Copper Alloy-Steel Bimetallic Bearing Materials and Manufacturing Technology

Combining copper alloy with steel back to make bearing bush can not only improve the strength of bearing bush, but also prolong the life of bearing bush, which is called bimetallic bearing. In this paper, the development status of copper alloy materials in bimetallic bearing bushes and the manufacturing principle and characteristics of copper alloy-steel bimetallic bearing bushes are summarized, and the defects of several manufacturing processes are analyzed. This paper summarizes the research on improving the performance of copper-steel bimetallic bearing bush. Finally, the development direction of the preparation process of copper alloy-steel bimetal is prospected.
