An heating material’s forms are wire and stripe.

it is divided by Fe-Cr-Al heating material and Ni-Cr material on its elements.

Its workable temperature is between 50 ºC and 1425ºC.

Fe-Cr-Al heating material is high resistance and endure high temperature.

It is better than Ni-Cr heating material in terms of performance and durability but weak in ambient gas.

Ni-Cr heating material is easy to manufacture and endure ambient gas but its workable temperature is lower than Fe-Cr-Al and it is Ni-Cr heating material’ disadvantage.
