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
