Copper wire is usually made of hot-rolled copper plate is not annealed, but the smaller size of the wire may require intermediate annealing drawn wire, it can be used for mesh, cable, copper brush and filter, copper wire is divided into brass, copper, phosphorus copper, which includes brass wire.

Brass wire, which contains 65% copper and 35% zinc, is widely used in industrial filtration, petroleum, chemical, printing, cable and other industries. At the same time, It is also widely used in wire, electronics, hardware parts processing, cold heading nail and screw, avionics accessories, telecommunications devices, connector connector performance, ornaments and embedded wire, fishing line and other aspects.

At the same time, brass wire can also be used as a conductor, although the electrical conductivity of silver is stronger, 100, copper is 99, but the cost of life is relatively high, and at the same time the cost is relatively low, widely made, therefore, copper wire is used instead of silver as a conductor.
