Main technical properties of FeCrAl alloy wire:

①The use temperature is high, the use temperature of the iron-chromium aluminum alloy wire in the atmosphere can reach 1300℃;

②Long service life;

③The allowable surface load is large;

⑤The specific gravity is smaller than the nickel-chromium alloy; ④The oxidation resistance is good, and the AI2O3 film formed after oxidation has good chemical resistance and high resistivity;

⑥High resistivity;

⑦Good sulfur resistance;

⑧The price is significantly lower than that of nickel-chromium alloy;

⑨The disadvantage is that as the temperature increases, it exhibits plasticity, and the strength at high temperatures is low.

The characteristics of nickel-chromium electric stove wire are:

① High strength at high temperature;

②Cool down after long-term use, the material will not become brittle;

③The emissivity of fully oxidized Ni-ming alloy is higher than that of Fe-Cr-Al alloy;

④No magnetism;

⑤Except for sulfur atmosphere, it has better corrosion resistance
