Overview
0Cr25Al5 is a high-performance iron-chromium-aluminum alloy (Fe-Cr-Al) designed for high-temperature electric heating applications. With 25% chromium (Cr), 5% aluminum (Al), and balanced iron (Fe) plus trace rare earth elements, it offers exceptional oxidation resistance, high resistivity, and extended service life, widely used in industrial heating elements, household appliances, and precision thermal control systems.
