Constantan(Cu-Ni) has the best temperature-resistance linearity.
In order to adapt the insulation environment, this kind of alloy wires could be coated with high performance insulation laquer.
Good corrosion resistance, weldability and machinability.
CuNi44 Resistance wire/ constantan / copper nickel alloys
is universally known as Constantan or Konstantan, its high specific resistance and negligible temperature coefficient of resistance are its most important attributes. For others, the fact that CuNi44 offers good ductitility, is easily soldered and welded and has good resistance to atmospheric corrosion is more significant.
