14AWG 1.60mm Iron Chrome FeCrAl Alloy 0Cr21Al4 Heating Resistance
Wire For Industry Heating Elements
General Introduction:
0Cr21Al4 is a type of iron-chromium-aluminum (FeCrAl) alloy with
the following composition:
21% Chromium (Cr)
4% Aluminum (Al)
Iron (Fe) and trace amounts of other elements.
This alloy is known for its high resistance to oxidation and
corrosion at high temperatures, making it suitable for use in
