Please refer to our FAQ for details.Constantan wire is composed of a copper-nickel-manganese alloy, containing about 59% copper, 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 is commonly used as a resistance alloy, similar to manganin.Evek GmbH is a trusted supplier of constantan wire. Our online shop offers a variety of constantan wires that are ready for immediate delivery.2.0842 CuNi44 wire is easy to process, weld, and braze. It offers excellent resistance to corrosion and oxidation, and has high ductility. However, it is not suitable for use in electrical precision resistors—for such applications, manganin is recommended.Typical uses for constantan wire include: - Manufacturing thermocouples and heating resistors (operating temperatures up to 400-500°C) - Producing rheostats and potentiometers - Production of measuring resistorsKey properties of 2.0842 CuNi44 wire: - High electrical resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Good ductility - Stable expansion coefficient - Excellent resistance to corrosion and oxidationTo purchase constantan wire, please contact Evek GmbH. We offer constantan wires at competitive prices and maintain them in stock for quick dispatch.
