CuNi44 Flat Wire Cooper Nickel Alloy Wire 0.2*3mm Small Size Available
CuNi44 (UNS C72150/2.0842) is a copper-nickel alloy (CuNi alloy) characterized by high electrical resistance, high ductility and good corrosion resistance. It is suitable for use at temperatures up to 600℃.
CuNi44 offers high electrical resistivity and very low temperature coefficient of resistance (TCR). Due to its low TCR, it finds use in wire-wound precision resistors that can operate up to 400°C (750°F). This alloy is also capable of developing a high and constant electromotive force when coupled with copper. This property allows it to be used for thermocouple, thermocouple extension and compensating leads. It is easily soldered, welded, and offers good corrosion resistance against atmospheric conditions.
