QSn4-3 tin bronze: tin bronze containing zinc. It has high wear resistance and elasticity, good anti-magnetic properties, can withstand hot or cold pressure processing well; in hard state, good machinability, easy welding and brazing, corrosion resistance in atmosphere, fresh water and sea water good sex. It is used to make springs (flat springs, round springs) and other elastic components, corrosion-resistant parts and wear-resistant parts (such as bushings, discs, bearings, etc.) and anti-magnetic parts on chemical equipment, and scrapers for the paper industry.
QSn4-4-2.5 tin bronze: tin bronze added with zinc and lead alloying elements. It has high friction reduction and good machinability, easy to weld and braze, and has good corrosion resistance in the atmosphere and fresh water; pressure processing can only be carried out in cold state, due to lead, it is easy to cause hot brittleness during daily processing . It is used to make bearings, crimping sleeves, complete sets, discs and inner pads for bushings that work under friction conditions.

It is used to make bearings, crimping sleeves, complete sets, discs and inner pads for bushings that work under friction conditions. The use temperature can reach below 300 ℃, and it is a kind of tin bronze with good thermal strength.
QSn6.5-0.1 tin bronze: Phosphor bronze. It has high strength, elasticity, wear resistance and anti-magnetic properties, good pressure workability in hot and cold states, high flame resistance to spot sparks, can be welded and brazed, and has good machinability. Corrosion resistant in fresh water. Tin bronze manufacturers are used to make springs and spring contact pieces with good conductivity, wear-resistant parts and anti-magnetic parts in precision instruments, such as gears, brush boxes, vibrating plates, and contactors.
QSn6.5-0.4 tin bronze: Phosphor bronze. The performance and use are similar to QSn6.5-0.1. Due to the high phosphorus content, it has high fatigue strength, good elasticity and wear resistance, but it has hot brittleness during hot processing and can only be processed by cold pressure. In addition to being used as springs and wear-resistant parts, it is mainly used in the paper industry to make wear-resistant copper mesh and unit load <1000N/cm2=circumferential speed 370℃), processing (annealing, welding, etc.) and use in reducing atmosphere. Hebei tin bronze is suitable for the manufacture of wires, cables, conductive screws, detonators, chemical evaporators, gaskets, rivets, nozzles, etc.
