20/22/24 AWG Copper Nickel Filament Wire CuNi23 Silver White Round Wire
Introduction:
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.
