Iron-Chromium-Aluminium 0cr21al6 Ferro Chrome Aluminium Fecral Electric Heating Element

Product Description

Product Description

Introduction of FeCrAl resistance wire
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.
Nichrome heating alloy includes pure nickel, NiCr alloy, Fe-Cr-Al alloy and copper nickel alloy.
FeCrAl resistance wire grade: 0Cr25AL5, 0Cr23AL5, 0Cr27AL7Mo2, 0Cr21AL4, 0Cr21Al6.
In the form of wire, ribbon and strip
Wire: 0.018mm-10mm
Ribbon: 0.05*0.2mm-2.0*6.0mm
Strip: 0.5*5.0mm-5.0*250mm
Feature of FeCrAl resistance wire 
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.
Advantage of FeCrAl resistance Wire
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)
