Tin-based alloys are used in the manufacture of plain bearings (bearings), usually attached to the housing of the bearing housing to reduce friction, also known as bearing alloy. Babbitt is white and is often referred to as " white metal " . The main components of the alloy are tin, lead, antimony and copper; tin and lead are used to improve the antifriction properties of the alloy, and niobium and copper are used to increase the strength and hardness of the alloy. Babbitt alloy has developed into dozens of grades, which are widely used in various countries, and the composition of the corresponding alloy grades is very similar.

The tin-based bearing alloy grades are indicated by the "Ch" symbol. The front of the grade is marked with "Z", indicating that it is a cast alloy. For example, the tin-based bearing alloy grade containing Sbll % and Cu6 % is "ZChSnSb11-6" .
Also available as bearing materials are copper-based alloys, aluminum-based alloys, silver-based alloys, nickel-based alloys, tin-based alloys, and the like. Among these bearing materials, tin-based alloys and aluminum-based alloys are most used. When tin-based bearing alloys are used, tin-based alloys and steel are usually rolled back together for bimetallic applications. Other alloys are only used in special cases. For example, to reduce weight, some aero-engines use nickel-based alloys as bearings;

The bearing alloy should have the following properties: 1 Good antifriction performance. It is required that the friction coefficient between the bearing bush made of the bearing alloy and the shaft is small and has good lubricity. 2 has a certain compressive strength and hardness. Can withstand the pressure exerted by the rotating shaft; but the hardness should not be too high, so as not to wear the journal. 3
