Constantan is a copper-nickel alloy with high electrical resistance and low-temperature coefficient of resistance. It’s commonly used in applications where precise resistance is required, such as in strain gauges, resistors, and thermocouples. A 1-2mm Constantan wire refers to Constantan wire with a diameter ranging from 1 to 2 millimeters.
Applications of 1-2mm Constantan wire may include:
- Strain gauges for measuring mechanical stress and strain in structures and materials.
- Resistors for precision electrical circuits where stable resistance is critical.
- Heating elements in specialized applications where controlled heating is required.
- Thermocouples for temperature measurement, especially in low-temperature ranges.
