Product Description

CuNi23 Resistance low temperature coefficient copper nickel binary alloy for heating cable of automobile heating cushion

Introduction
CuNi23 resistance alloy is one of copper nickel binary alloys, having low temperature coefficient of resistance. It is applied to make rheostat, shunt, controller and other low voltage electrical components with a maximum operating temperature of 300°C. Due to its good heat coefficient, this alloy is widely used in low temperature heating cable of automobile heating cushion, railway snow melting, etc.

Due to high tensile strength and increased resistivity values, the copper nickel alloy wires are the first choice for applications as resistance wires. With the different nickel amount in this product range, the characteristics of the wire can be chosen according to your requirements. Copper nickel alloy wires are available as bare wire, or enamelled wire with any insulation and self-bonding enamel. Furthermore, litz wire made of enamelled copper nickel alloy wire are available.

CuNi23Mn is a copper-nickel alloy (CuNi alloy) with medium resistivity for medium-low temperature resistances. The alloy is suitable for use at temperatures up to 400°C (750°F)

CuNi23Mn is very malleable and has a good resistance to corrosion until temperatures of 400°C. Ideal applications areas are all types of resistances used at low temperature.

CuNi23Mn is typically used in heating cables, fuses, resistors and various types of controllers.
