    Copper-Nickel wire

    CuNi2 fine wires Copper-based low resistance heating alloy series possess the features of low resistance temperature coefficient, wide area of working temperature , good welding function etc. It is widely used in the area to make heating cable, adjustable resistor and strain resistor etc. The most common alloys are CuNi2, CuNi6, CuNi10, CuNi23, CuNi30, CuNi44, 6J40, 6J11, 6J12, 6J8, 6J13, Monel 400, Monel 500 etc.
