Tin based Babbitt alloy, also known as SnSbCu alloy, has excellent wear resistance, corrosion resistance, thermal conductivity, and toughness, and is widely used in the wear-resistant layer of bearings or bushings. Tin based Babbitt alloys mainly include grades such as SnSb11Cu6 (SnSbCu-11-6), SnSb8Cu4 (SnSbCu-8-4), SnSb4Cu4 (SnSbCu-4-4), etc.
