Tin bronze bronze sleeve refers to a copper sleeve processed from tin bronze. The tin content of tin bronze is generally between 3% and 14%, and it is mainly used to make elastic components and wear-resistant parts. The tin content of wrought tin bronze does not exceed 8%, and elements such as phosphorus, lead, and zinc are sometimes added. Adding lead to tin bronze can improve machinability and wear resistance, and adding zinc can improve casting performance.
This alloy has high mechanical properties, anti-wear properties and corrosion resistance, easy cutting processing, good brazing and welding properties, small shrinkage coefficient, and non-magnetic. With high strength, corrosion resistance and excellent casting performance, it has been widely used in various industrial sectors for a long time.
Tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage rate. It can be used to produce castings with complex shapes, clear contours 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 marine ship parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts of high-precision machine tools.
Tin bronze copper sleeves are the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used in various cables and wires, motors and transformers, switches and printed circuit boards. In the manufacture of machinery and transportation vehicles, it is used in the manufacture of industrial valves and fittings, meters, sliding bearings, molds, heat exchangers and pumps.
Tin bronze bronze sleeves cast with tin bronze are also widely used in various mechanical equipment with higher requirements. Commonly used grades are QSn4-3, QSn4.4-2.5, QSn7-O.2, ZQSn10-1, ZQSn5-2-5, ZQSN6-6-3, etc.
