Characteristic and use

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.
