The 2.0842 CuNi44 wire belongs to the group of resistance alloys and is comparable to manganin.Evek GmbH is your trusted source for constantan wire. Our online shop offers a wide selection of constantan wires, ready for immediate dispatch.2.0842 CuNi44 wire is easy to machine, weld, and braze. It features high resistance to corrosion and oxidation, as well as excellent ductility. Note: This wire is not suited for electrical precision resistors; manganin is preferred for such applications.Common uses for constantan wire include: - Manufacturing thermocouples and heating resistors (for operating temperatures up to 400–500°C) - Production of rheostats and potentiometers - Measuring resistor fabricationKey properties of 2.0842 CuNi44 wire: - High electrical resistivity - Low temperature coefficient of resistance - High Seebeck coefficient - Good ductility and expansion coefficient - Outstanding resistance to corrosion and oxidationTo purchase constantan wire, reach out to Evek GmbH.
