Manganin 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-corrosiveand easy braze welding. Used in manufacturing regenerator's variable resistor and the strain resistor.
Manganin common temperature classes are 130, 155, 180 C,200,220
Manganin is a trademarked name for an alloy of typically 86% copper, 12% manganese, and 2% nickel.
