Constantan wire is made from a copper-nickel-manganese alloy. This consists of approx. 59% copper with the addition of 39-41% nickel and 1-2% manganese and is non-magnetic. 2.0842 CuNi44 wire has a low temperature coefficient of electrical resistance and is one of the resistance alloys (along with manganin).

Evek GmbH is your reliable and competent supplier for constantan wire. In our online shop you will find wires made of Constantan ready for delivery and dispatch.

2.0842 CuNi44 wire is easy to process, weld and braze. It is also very resistant to corrosion and oxidation. This wire is not suitable for electrical precision resistors. Manganin can be recommended for these. Constantan wire has a high ductility.

Typical areas of application for constantan wire are:

  • Manufacture of thermocouples and heating resistors (with operating temperatures of up to 400-500 ° C);
  • Manufacture of rheostats and potentiometers;
  • Production of measuring resistors.

2.0842 wire CuNi44 is characterized by:

  • high resistivity;
  • low temperature coefficient of resistivity;
  • high Seebeck coefficient;
  • good ductility;
  • good expansion coefficient;
  • high corrosion and oxidation resistance.
