Constantan wire is an alloy composed mainly of copper (approx. 59%), with 39-41% nickel and 1-2% manganese, making it non-magnetic. The 2.0842 CuNi44 wire is well-known for its low temperature coefficient of electrical resistance and belongs to the resistance alloys group, similar to manganin. Evek GmbH is your trusted source 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 is highly resistant to corrosion and oxidation, and features excellent ductility. Note: It is not recommended for electrical precision resistors; for these, manganin is a better choice. Common uses for constantan wire include: - Manufacturing thermocouples and heating resistors (operating temperatures up to 400–500°C) - Production of rheostats and potentiometers - Fabrication of measuring resistors Key properties of 2.0842 CuNi44 wire: - High electrical resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Excellent ductility - Good thermal expansion coefficient - Outstanding resistance to corrosion and oxidation To purchase constantan wire, please contact Evek GmbH. We offer constantan wires at competitive prices and maintain a consistent stock for fast delivery.
