All wires stable resistance, anti-oxidation, corrosion resistance
CuNi23 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)
CuNi23 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.
CuNi23 is typically used in heating cables, fuses, resistors and various types of controllers.
