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.
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.
