Copper-Nickel Alloys: CuNi44
Copper-Nickel Alloys: CuNi44
49 AlloyCuNi44 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.
