This non-magnetic wire, also known as 2.0842 CuNi44, has a low temperature coefficient of electrical resistance, making it a popular resistance alloy alongside manganin.At Evek GmbH, we are your dependable supplier for constantan wire. Our online shop offers a wide range of constantan wires ready for immediate shipping.The 2.0842 CuNi44 wire is easy to process, weld, and braze. It offers excellent resistance to corrosion and oxidation, and features high ductility. However, it is not intended for use in electrical precision resistors—manganin is a better choice for that purpose.Common uses for constantan wire include: - Manufacturing thermocouples and heating resistors (operating temperatures up to 400-500°C) - Producing rheostats and potentiometers - Fabrication of measuring resistorsKey properties of 2.0842 CuNi44 wire: - High 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 competitive prices and maintain a consistent stock for quick delivery.
