They are used for the manufacture of electric resistances for appliances (insulated elements type tubular resistances or for example opened elements on micanit plate) or for application of industrial furnaces.
In addition of a relatively high specific resistance, Ni-Cr alloys join all the necessary properties for good performances in use of furnaces: Resistance to oxidation (they are not sensitive to aggressions of humid air).
