Product Description

Copper Nickel Resistance Wire
Copper-based heating resistance alloy wire has lower electrical resistance, good echanical,excellent welding and anti-corrosion properties.It is used to make the key components in the thermal overload relay, low resistance thermal circuit breaker, and the electrical appliances. It is also an important material for electrical heating cable.
 Constantan is a type of resistance alloy,which is made up of copper and nickel as the main components.It has a low  temperature coefficient of resistnce(TCR),and a wide operating temperature range (below 500ºC).It has good properties on machanical working,high resitance of corrosion.It is used for variable and strain resitance elements in alternative  instruments.
