    CuNiCopper Nickel Alloy Resistor 0.10mm-10.00mm Constantan Heating Resistance Wire


    Constantan is a copper-nickel alloy that is widely used in various applications, particularly for its electrical and thermal properties. Here are some key details about constantan wire:

    1. Composition:

      • Constantan is typically composed of approximately 55% copper and 45% nickel.
      • The precise copper-nickel ratio can vary slightly depending on the specific alloy composition.
    2. Electrical Properties:

      • Constantan has a high electrical resistivity, making it suitable for use in resistors, thermocouple wires, and resistance temperature detectors (RTDs).
      • It has a low and stable temperature coefficient of resistance, which is an important property for applications where precise resistance measurement is required.
    3. Thermal Properties:

      • Constantan has a relatively low thermal conductivity compared to pure copper, which makes it useful for applications where thermal isolation is needed.
      • It also has a high Seebeck coefficient, making it a popular choice for thermocouple applications where the generation of a thermoelectric voltage is desired.
    4. Applications:

      • Thermocouple wires: Constantan is commonly used as one of the two wires in Type T (copper-constantan) thermocouples, which are widely used in temperature measurement applications.
      • Resistors: Constantan wire is used to make precision resistors due to its stable electrical resistance.
      • Strain gauges: Constantan's electrical resistance change under stress makes it suitable for use in strain gauge applications.
      • Electrical components: Constantan wire is used in various electrical components, such as potentiometers and rheostats.

    Constantan wire is available in a range of diameters and is commonly used in various industrial, scientific, and engineering applications that require its unique electrical and thermal properties.
