Constantan wire is crafted from a copper-nickel-manganese alloy, typically containing about 59% copper, 39-41% nickel, and 1-2% manganese. This non-magnetic alloy, known as 2.0842 CuNi44, features a low temperature coefficient of electrical resistance, placing it among resistance alloys like manganin. Evek GmbH is your trusted supplier of constantan wire. Our online shop offers a selection of constantan wires ready for prompt delivery. The 2.0842 CuNi44 wire is easy to process, weld, and braze. It exhibits excellent resistance to corrosion and oxidation and offers high ductility. However, it is not suitable for use in electrical precision resistors; for such applications, manganin is recommended. Common uses for constantan wire include: - Production of thermocouples and heating resistors (operating temperatures up to 400-500°C) - Manufacturing rheostats and potentiometers - Producing measuring resistors The key properties of 2.0842 CuNi44 wire are: - High resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Good ductility - Stable coefficient of expansion - Excellent resistance to corrosion and oxidation To purchase constantan wire, please contact Evek GmbH. We offer constantan wires at competitive prices and maintain a reliable stock for quick delivery.
