0Cr21Al4 FeCrAl strip is a ferritic alloy consisting mainly of iron, chromium (around 21%), and aluminum (around 4%). This unique blend creates a material that resists oxidation at high temperatures while maintaining stable resistivity. Its primary role is to serve as a heating element, and it excels at converting electrical energy into consistent heat output. Unlike conventional stainless steel or nickel-based alloys, 0Cr21Al4 FeCrAl strip is optimized for long-term, high-temperature use, making it especially valuable in infrared heating applications.
Infrared Heaters depend on materials that can emit stable radiation without degrading. The 0Cr21Al4 alloy meets this requirement by combining strength with efficiency, ensuring heating devices last longer and require less maintenance.
