NiCr Alloy Electrical Resistance Heating Wire NiCr8020 For Heater Furnaces


Resistance wire is wire intended for making electrical resistors (which are used to control the amount of current in a circuit). It is better if the alloy used has a high resistivity, since a shorter wire can then be used.


How does a resistance wire work?

The moving electrons can collide with the ions in the metal.

This makes it more difficult for the current to flow, and causes resistance.

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through.
