Bronze with tin as the main alloying element. Tin content is generally 3 ~ 14%, mainly used for making elastic components and wear resistant parts. The tin content of deformed tin bronze is less than 8%, and phosphorus, lead, zinc and other elements are sometimes added. Phosphorus is a good deoxidizer and improves fluidity and wear resistance. The machinability and wear resistance of tin bronze can be improved by adding lead, and the casting performance can be improved by adding zinc. This kind of alloy has higher mechanical properties, wear reduction properties and corrosion resistance, free cutting, good brazing and welding properties, small shrinkage coefficient, non-magnetic. The coatings of bronze bushing, shaft bushing and diamagnetic element can be prepared by wire flame spraying and arc spraying. With high strength, corrosion resistance and excellent casting properties, it has been widely used in various industrial sectors for a long time.
