Copper Nickel Alloy Wire CuNi44 Constantan Flat Wire 0.2*0.7mm Used For Shunt's Elements
Product Description
Copper nickel alloy Wire with moderate resistivity and low
temperature coefficent of resistance with a flat
resistance/temperature curve over a wider range than the
"manganins". it also shows better corrosion resistance, and welding
performance. It always used for thermal overload relay, low-voltage relay etc.
