This non-magnetic material, also known as CuNi44 (2.0842), is part of the resistance alloys group and is known for its low temperature coefficient of electrical resistance, similar to manganin.Evek GmbH is your trusted source for constantan wire. Our online shop offers a variety of constantan wires that are ready for immediate dispatch.CuNi44 (2.0842) wire is easy to process, weld, and braze, and it offers excellent resistance to corrosion and oxidation. While it is not recommended for use in precision electrical resistors (manganin is preferable for those applications), constantan wire stands out for its high ductility.Common applications for constantan wire include:- Thermocouples and heating resistors (suitable for operating temperatures up to 400–500°C) - Rheostats and potentiometers - Measuring resistorsKey features of CuNi44 (2.0842) constantan wire:- High electrical resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Excellent ductility - Stable thermal expansion - Strong resistance to corrosion and oxidationTo purchase constantan wire, please get in touch with Evek GmbH. We offer constantan wires at competitive prices and maintain a ready supply in stock.
