Copper Nickel Foil
Copper-Nickel Foil is one kind of copper alloy that has high resistivity. It has very low temperature coefficient of resistivity (about 0.48μΩ·m) andmedium resistivity. That makes it can work very well in a wide temperature range. It has good machining and welding performance when used in AC circuits as precision resistors, sliding resistors and resistance strain gauges etc. It can also be made into thermocouples and its compensation wire materials.
