Characteristic and usage

It is the electric resistance alloy with the copper nickel as the essential component. It has the low resistance temperature coefficient, wide working temperature scope (500℃ below), good machining property, anti-corrosive and easy braze welding. Used in manufacturing regenerator's variable resistor and the strain resistor.
