Constantan wire is a non-magnetic copper-nickel-manganese alloy, consisting of approximately 59% copper, 39-41% nickel, and 1-2% manganese. Also known as 2.0842 CuNi44, this wire features a low temperature coefficient of electrical resistance, making it a popular resistance alloy alongside manganin. Evek GmbH is your trusted source for high-quality constantan wire. Our online shop offers a variety of Constantan wires, available for immediate dispatch. CuNi44 (2.0842) wire is easy to work with, weld, and braze. It offers excellent resistance to corrosion and oxidation, as well as high ductility. While it is not recommended for use in electrical precision resistors (for which manganin is more suitable), constantan wire is widely used in: - Thermocouple and heating resistor production (operating up to 400-500°C) - Rheostat and potentiometer manufacturing - Measuring resistor fabrication Key properties of 2.0842 CuNi44 wire include: - High electrical resistivity - Low temperature coefficient of resistivity - High Seebeck coefficient - Excellent ductility - Good coefficient of expansion - Strong resistance to corrosion and oxidation For constantan wire purchases, reach out to Evek GmbH. We offer fair prices and maintain a steady stock for fast delivery.
