CuNi44 resistance wire / constantan / copper nickel alloys
is universally known as Constantan or Konstantan, its high specific resistance and negligible temperatuer coefficient of resistance are its most important attributes. For others, the fact that CuNi44 offers good ductitlity, is easily soldered and welded and has good resistance to atmospheric corrosion is more significant.
