For details, please refer to our FAQ.Constantan wire is an alloy composed mainly of copper (about 59%), with 39–41% nickel and 1–2% manganese, making it non-magnetic. The 2.0842 CuNi44 wire features a low temperature coefficient of electrical resistance and belongs to the group of resistance alloys, similar to manganin.Evek GmbH is your trusted supplier for constantan wire. Our online shop offers a wide selection of constantan wires ready for immediate shipping.2.0842 CuNi44 wire is easy to process, weld, and braze, and offers excellent resistance to corrosion and oxidation. While it is not suitable for precision electrical resistors (for which manganin is recommended), constantan wire is highly ductile and versatile.**Common applications for constantan wire include:** - Production of thermocouples and heating resistors (usable at temperatures up to 400–500 °C) - Manufacture of rheostats and potentiometers - Production of measuring resistors**Key features of 2.0842 CuNi44 wire:** - High resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Excellent ductility - Good expansion coefficient - Strong resistance to corrosion and oxidationContact Evek GmbH to purchase constantan wire.
