Konstantan wire/CuNi44 wire/cuprothal294 wire/cupron wire.
small qty we can supply,and 0.003mm we can do.low resisivity.
 constantan wire /cuni44 wire/ copper nickel alloys
which used in manufacture of wire-wound precision resistors, volume control devices,etc
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.
