Bronze with tin as the main alloy element bai. The tin content is generally between 14% and 14%, which is mainly used to make elastic components and wear-resistant parts. The tin content of deformed tin bronze is not more than 8%, and sometimes phosphorus, lead, zinc and other elements are added. Phosphorus is a good deoxidizer, but also can improve the mobility and wear resistance. With high strength, corrosion resistance and excellent casting properties, it has been widely used in various industrial departments for a long time.

以錫為主要合金元素bai的青銅。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。具有較高的強度、耐蝕性和優良的鑄造性能,長期以來廣泛應用于各工業部門中。

Bronze containing% ~ 14% tin, in addition, phosphorus, zinc, lead and other elements are often added. It is the earliest alloy used by human beings, and has a history of about 4000 years. It is corrosion resistant, wear-resistant, has good mechanical and technological properties, and can be well welded and brazed, and does not produce sparks when impact. It is divided into processed tin bronze and cast tin bronze. The tin content of tin bronze used for pressure processing is less than 6% ~ 7%, and the tin content of cast tin bronze is 10% ~ 14%.

含有3%~14%錫的青銅,此外還常常加入磷、鋅、鉛等元素。是人類應用最早的合金,至今已有約4000年的使用歷史。它耐蝕、耐磨,有較好的力學性能和工藝性能,并能很好地焊接和釬焊,沖擊時不產生火花。分為加工錫青銅和鑄造錫青銅。用于壓力加工的錫青銅含錫量低于6%7%,鑄造錫青銅的含錫量為10%14%。

Tin bronze is the nonferrous metal alloy with the lowest shrinkage, which can be used to produce castings with complex shape, clear outline and low air tightness. Tin bronze is very corrosion resistant in atmosphere, seawater, fresh water and steam, and is widely used in steam boilers and sea ship parts. Tin green containing phosphorus has good mechanical properties and can be used as wear-resistant and elastic parts of high precision working master machine. Lead-tin bronze is often used as wear-resistant parts and sliding bearings. Zinc-containing tin bronze can be used as high air tightness casting.

錫青銅是鑄造收縮率最小的有色金屬合金,可用來生產形狀復雜、輪廓清晰、氣密性要求不高的鑄件。錫青銅在大氣、海水、淡水和蒸汽中十分耐蝕,廣泛用于蒸汽鍋爐和海船零件。含磷錫青銅具有良好的力學性能,可用作高精密工作母機的耐磨零件和彈性零件。含鉛錫青銅常用作耐磨零件和滑動軸承。含鋅錫青銅可作高氣密性鑄件。
