The color of tin bronze is a problem that many people will be concerned about, because it affects the price of tin, and the price of tin bronze should be based on the market price of the day. Tin bronze is the dark color of the alloy of red copper, tin and lead. Tin bronze is yellowish to blue, so it is also called tin bronze. It has high strength, corrosion resistance and excellent casting performance, and has been widely used in various industrial sectors for a long time.
Domestic tin bronze is divided into two grades, QSn4-4-2.5 and QSn4-4-4 according to different chemical compositions. Tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage rate. It is used to produce castings with complex shapes, clear outlines and low air tightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers. And sea ship parts.
And tin bronze has high friction reduction; easy cutting processing; only suitable for cold processing; easy welding and brazing; good corrosion resistance in the atmosphere and fresh water. Mainly used in parts that bear friction in aviation, automobile, tractor industry and other industries, such as bushings, discs, bushings, etc. The color deviation of tin bronze has a great influence on its component content and use.
