Alloy | Main Features | Application Examples |
QSn6.5-0.1 | High strength, elasticity, abrasion resistance and anti-magnetic, good cold workability, corrosion resistance, weldability and machinability, are widely used in the manufacture of flexible components, wear-resistant parts in precision instrumentation and anti-magnetic Components. | In the aviation industry is mainly used for the manufacture of a variety of altimeter and diaphragm, bellows and bellows. Thermal stabilization of the part to be stress relieved can improve the fatigue resistance of the material. |
QSn7-0.2 | The α phase solid solution produced a small amount of (α + δ) eutectoid, δ phase is a hard and brittle phase, with a large content will reduce the alloy plasticity and mechanical properties. Has high strength, hardness, high elasticity and abrasion resistance, high corrosion resistance in the atmosphere, fresh water and seawater, easy to weld. | It is mainly used for manufacturing wear-resistant parts and structural parts that work under medium carrier and moderate East China speed, such as wear washers, bearings, bushings and turbines. It also can manufacture springs, reeds and other mechanical and electrical parts. |
