QSn10-0.3 Description
QSn10-0.3 phosphor bronze strip was produced by electromagnetic stirring, horizontal continuous casting, cold finishing rolling and multiple intermediate annealing.
Its ultra-hard tensile strength can reach 1000 ~ 1200 MPa, elongation about 2.5%, which can meet the requirements of some users for high strength and high elasticity strip, and can also partially replace beryllium bronze strip.
応用
The products have good wear resistance and corrosion resistance, good cold processing, excellent welding performance, mainly used for making high-strength super-elastic fatigue resistant parts.
QSn10-0.3 Mainly used in the manufacture of elastic components, wear-resistant parts and anti-magnetic parts in precision instruments, such as spring contact pieces or other springs with good electrical conductivity; various altimeters in the aviation industry, springs for lifting speedometers, connecting rods, etc. , Gears, brush boxes, contactors, etc. in precision instruments.
