Nichrome's metallurgical structure confers them a very good plasticity when cold.

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).

Low embrittlement at high temperature. Good plasticity-Easier to give them a shape compared with FeCrAl (lower mechanical characteristics allow indeed a good control of elasticity of the product during shaping (coiling, folding, drawing).

Good resistance to creeping (more important than ferritic alloys) which is important during conception of a resistance presenting big heights of waves.
