Tin bronze stick

The tin content of tin bronze is generally between 3% and 14%. It is mainly used to make elastic components and wear-resistant parts. The content of tin in wrought tin bronze is less than 8%, and phosphorus, lead and zinc are sometimes added. Phosphorus is a good deoxidizer and can improve the 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. The alloy has high mechanical properties, wear resistance and corrosion resistance, easy cutting, good brazing and welding properties, small shrinkage coefficient and no magnetism. The coating of bronze bushing, shaft sleeve and diamagnetic component can be prepared by flame spraying and arc spraying.

錫青銅 含錫量一般在3～14％之間,主要用于制作彈性元件和耐磨零件。變形錫青銅的含錫量不超過 8％，有時還添加磷、鉛、鋅等元素。磷是良好的脫氧劑，還能改善流動性和耐磨性。錫青銅中加鉛可改善可切削性和耐磨性，加鋅可改善鑄造性能。這種合金具有較高的力學性能、減磨性能和耐蝕性，易切削加工，釬焊和焊接性能好，收縮系數小，無磁性。可用線材火焰噴涂和電弧噴涂制備青銅襯套、軸套、抗磁元件等涂層。
