Bronze with tin as the main alloying element. The content of tin is generally between 3 ~ 14%, which is mainly used to manufacture elastic components and wear-resistant parts. The tin content of deformed tin bronze is less than 8%, and sometimes elements such as phosphorus, lead and zinc are added. Phosphorus is a good deoxidizer, and it can also improve fluidity and wear resistance. Adding lead to tin bronze can improve cutting performance and wear resistance, and adding zinc can improve casting performance. This alloy has high mechanical properties, wear resistance and corrosion resistance, easy cutting, good brazing and welding performance, small shrinkage coefficient and no magnetism. Coatings such as bronze bushings, bushings and diamagnetic elements can be prepared by wire flame spraying and arc spraying. The size specifications are Ф1.6 mm and Ф 2.3 mm. It has high strength, corrosion resistance and excellent casting performance, and has been widely used in various industrial sectors for a long time.
