Explanation

Also known as Babbitt metal or tin based white alloy, it is a widely used bearing materials in industry. It is a alloy based on tin and added with antimony, copper and other elements. Some common tin-base bearing alloy include Sn-12Sb-4Cu-10Pb, Sn-11Sb-6Cu, Sn-8Sb-4Cu, and Sn-4Sb-4Cu. The typical structure of tin-base bearing alloy is α The matrix of tin (alpha tin) solution is evenly distributed with hard phase SnSb, which has excellent wear resistance. In addition, imermetallif compound Cu6Sn5 can prevent density segregation during solidification. Based on tin, this alloy has good wear resistance, good plasticity, excellent running in performance, can effectively resist inlay and anti seizure, and has excellent heat resistance and corrosion resistance. Therefore, tin-base bearing alloy is suitable for manufacturing bearings that need to withstand high speed, high pressure and impact load. In order to improve the strength of alloy and save the use of tin, the casting process is usually used as the bearing shell material to make bimetal bearing shells. This design structure can effectively reduce the cost while maintaining the performance of alloy.
