Brass wire is a type of copper wire. The interior of the wire is made of high-quality brass, which can greatly improve the conductivity of the brass wire. The exterior of the brass wire is insulated with high-quality rubber, while some use high-quality plastic as the outer protective layer, making the wire have strong conductivity and excellent outer insulation performance. Brass wire has good mechanical properties and good plasticity in the hot state. And the wire is relatively soft and durable, which can effectively avoid various unsafe accidents.
