RW 45 Nickel-Copper Resistance Wire - Advance
A Nickel-Copper alloy wire used mainly for its medium range
electrical resistivity and very low temperature-coefficient
of resistance.
Applications include power resistors, shunts, thermocouples and wire-wound precision resistors having operating temperatures up to 400°C.
