0.2mm Constantan wire

A 0.2mm Constantan wire refers to a wire made of Constantan alloy with a diameter of 0.2 millimeters. Constantan is a copper-nickel alloy known for its high electrical resistance and low temperature coefficient of resistance. This wire is commonly used in various applications where precise resistance values are required.

Here are some potential applications for 0.2mm Constantan wire:

1. Resistors: Constantan wire can be used as a resistance element in electronic circuits, providing stable resistance characteristics.
2. Strain Gauges: Thin Constantan wire can be bonded to surfaces to measure strain and deformation in materials, useful in structural health monitoring and material testing.
3. Thermocouples: Constantan wire can be utilized as one of the wires in thermocouples, which measure temperature differentials due to their predictable resistance-temperature characteristics.
4. Heating Elements: While not as common as some other materials like Nichrome, Constantan wire can still be used in specific heating applications where its properties are advantageous.
5. Temperature Sensors: Constantan wire can be used in temperature sensors and probes, especially in applications requiring stable resistance over a range of temperatures.
