 Application: bronze alloy is a copper alloy the best overall performance, it more than any other copper alloy with higher strength, hardness and elastic limit, its elastic hysteresis is small, flexible, high stability, excellent resistance to abrasion, corrosion resistance, high temperature and low temperature, fatigue resistance, good electrical conductivity and thermal conductivity; Additionally, there are non-magnetic, strike does not produce sparks and other characteristics, are widely used in aviation, electronics, telecommunications, machinery, chemicals, automotive and home appliance industries. Important key components used to make, such as the diaphragm, diaphragm, bellows, spring washer, micro-motor brush and commutator, electric connectors, switches, contacts, clock parts, audio components, high bearing, gear , automobile electronics, plastic mold, welding electrodes, submarine cables, pressure shell, no spark tools.
