This non-magnetic material, known as 2.0842 CuNi44 wire, features a low temperature coefficient of electrical resistance and belongs to the group of resistance alloys, alongside manganin.Evek GmbH is a trusted supplier of constantan wire. Our online shop offers constantan wires in stock, ready for quick delivery.2.0842 CuNi44 wire is easy to process, weld, and braze. It offers excellent resistance to corrosion and oxidation, as well as high ductility. However, it is not suitable for precision electrical resistors—manganin is recommended for those 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 - Making measuring resistorsKey properties of 2.0842 CuNi44 wire:- High electrical resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Good ductility - Stable coefficient of expansion - Excellent resistance to corrosion and oxidationTo purchase constantan wire, please contact Evek GmbH. We offer fair prices and always keep constantan wire in stock.
