Tin bronze, in addition to containing3%~14%Tin, often alloyed with elements such as phosphorus, zinc, and lead. It is one of the earliest alloys used by humans, with a history of approximately4000A history of use in years. It is corrosion and wear-resistant, boasts good mechanical and processing properties, and can be welded and brazed effectively without sparking during impact.

Tin bronze is divided into wrought and cast varieties. Tin bronze for pressure processing has a lower tin content than that for casting.6%~7%

The tin content for casting tin bronze is10%~14%Common brand numbers include:QSn4-3，QSn4.4-2.5，QSn7-O.2，ZQSn10，ZQSn5-2-5，ZQSN6-6-3Please wait.

Tin bronze is a non-ferrous alloy with low shrinkage during casting, suitable for producing castings with complex shapes, clear contours, and moderate gas-tightness requirements. Tin bronze exhibits excellent corrosion resistance in atmospheric, seawater, freshwater, and steam environments, and is widely used in steam boilers and marine parts.

Phosphorus tin bronze boasts excellent mechanical properties and is often used for wear-resistant and elastic parts in high-precision machine tools. Lead-tin bronze is commonly employed for wear-resistant parts and sliding bearings, while zinc-tin bronze is suitable for high-seal casting parts.
