FeCrAl alloy wire is typically used in industrial furnaces and home appliances. Examples of applications are elements embedded in ceramics for panel heaters, infrared heaters, warming plates, irons, ceramic pots, in cartridge heaters for liquid heating, storage heaters, in ceramic heaters for cooking plates, air guns, hobby kilns, radiators, in quartz tube heaters for space heating, toasters, toaster ovens, grills, industrial infrared dryers, coils on molded ceramic fibre for cooking plates with ceramic hobs.   Heating elements     Industrial electrical furnace, oven     1. Introduction of fecral resistance wire   FeCrAl
Iron-chromium-aluminium (FeCrAl) metallic alloy is a high temperature alloy which can be used up to 1400° C and is a popular material choice for industrial furnaces.    2. fecral resistance wire feature
1) Excellent resistance to oxidation under heating condition;
2) High resistance and long lifetime;
3) Low temperature coefficient;
4 )Good performance of anti-carburizing, the atmosphere and surface of sulfur pollution.   3. fecral resistance wire advantage  
Fe-Cr-Al resistance alloy has a good corrosion resistance at high temperature. 
Fe-Cr-Al resistance alloy is much cheaper than Nickel Chrome wire. 
Fe-Cr-Al resistance alloy wires are widely used in industrial furnacess, household appliances and far-infrared devices. 
Fe-Cr-Al resistance alloy surface useing temperature can be 1400 degree, (0Cr21A16Nb, 0Cr27A17Mo2 and so on).    4. Chemical composition and main properties
