Product Description

resistance wire manganin 

 CuNi alloy grade: Constantan, CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuMu12Ni, CuNi34, CuNi40 (6J40), CuNi44. 
 
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.
