General Description
CN49 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)
CN49 wire 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.
CN49 wireis typically used in heating cables, fuses, resistors and various types of controllers.
