The microstructure characteristic of tin-based alloys is that hard phase particles are uniformly distributed on a soft phase matrix. The soft phase matrix gives Babbitt alloy excellent embeddability, conformability, and anti-seizure properties. After running-in, the soft matrix becomes concave, and the hard particles protrude outward, creating tiny gaps between sliding surfaces that serve as oil storage spaces and lubricant channels, which helps reduce friction. The protruding hard particles provide support, aiding in load-bearing. In addition to manufacturing plain bearings, due to its soft texture and low strength, Babbitt alloy is often sprayed as wire or powder onto substrates such as steel to make bearing shells.
Tin-based bearing alloys, also known as tin-based Babbitt, white metal, or black gold, are widely used in machinery, chemical, shipbuilding, and power industries, including turbine bearing shells, motor bearings, and intermediate bearings, due to their excellent anti-friction, conformability, and embeddability properties.

Composition of tin-based alloys: The main components of tin-based bearing alloys are tin, lead, antimony, and copper. Antimony and copper are used to enhance the strength and hardness of the alloy. The main grades of tin-based alloys include 11-6, 4-4, 7.5-3, 12-3-10, 8-4, 12-4-10, 8-8, 10-6, etc. These alloys are used to manufacture bearing shells, bushings, and liners for mechanical plain bearings. They are primarily used in bearing shells for various types of ball mills in building material machinery; bearing shells for papermaking machinery such as beaters and dryer cylinders; bearing shells for various parts of turbines in hydropower equipment; bearing shells for ship machinery propellers; bearing shells for compressors, crushers, and rolling mills.
