CuNi8 Copper Nickel Resistance Wire NC012 Cuprothal 12 Low Temperature Heating Wire

CuNi8 Copper Nickel Resistance Wire (NC012 / Cuprothal 12)

CuNi8 is a copper nickel resistance alloy containing approximately 8% nickel. With a resistivity of about 0.12 micro-ohm.m and a low temperature coefficient of resistance, it bridges the gap between the low resistance CuNi2 and the higher resistance CuNi10 grades. The alloy provides stable resistance, good corrosion resistance and excellent ductility for winding and coiling, making it a reliable choice for low and medium temperature heating, precision resistance and compensating lead applications. The wire is supplied in a bright, soft annealed condition.

1. Key Features

• Moderate electrical resistivity of approx. 0.12 micro-ohm.m with a low temperature coefficient of resistance
