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
heating elements, industrial furnaces, and various electrical
applications. 0Cr21Al4 has good mechanical properties and can
withstand high temperatures up to around 1100°C.
Due to its excellent oxidation resistance, this alloy is commonly used in environments where high temperatures and harsh conditions are present. It is also known for its relatively low cost compared to some other high-temperature alloys, making it a popular choice in various industrial applications.
