0Cr21Al6 is a high-resistivity Fe-Cr-Al (Iron-Chromium-Aluminum) alloy, composed of approximately 21% chromium and 6% aluminum, with the balance being iron. This alloy is known for its excellent oxidation resistance, high electrical resistivity, and outstanding performance at elevated temperatures, making it ideal for use in electric heating elements.
0Cr21Al6 exhibits a maximum operating temperature of up to 1300°C, suitable for both industrial and household heating applications. Compared to Ni-Cr alloys, it offers a longer service life, lower density, and lower material cost, making it a cost-effective and high-performance heating solution.
