Bronze with tin as the main alloying element. The tin content is generally between 3 and 14%, and it is mainly used to make elastic components and wear-resistant parts. The tin content of deformed tin bronze does not exceed 8%, and sometimes elements such as phosphorus, lead, and zinc are added. Phosphorus is a good deoxidizer and also improves fluidity and wear resistance. Adding lead to tin bronze can improve machinability and wear resistance, and adding zinc can improve casting properties. This alloy has high mechanical properties, anti-wear properties and corrosion resistance, easy cutting, good brazing and welding properties, small shrinkage coefficient, and non-magnetic. Bronze bushings, bushings, diamagnetic elements and other coatings can be prepared by wire flame spraying and arc spraying. Size specifications are Ф1.6mm, Ф2.3mm. With high strength, corrosion resistance and excellent casting properties, it has been widely used in various industrial sectors for a long time.
