The 0Cr27Al7Mo2 FeCrAl strip is a high-resistance alloy composed primarily of iron, chromium, aluminum, and molybdenum. The chromium content provides structural strength, the aluminum ensures oxidation resistance, and the molybdenum adds extra durability against corrosion and mechanical stress at elevated temperatures. This combination makes it one of the most reliable alloys for applications requiring continuous operation at temperatures up to 1450°C.
The aluminum in the alloy forms a protective aluminum oxide (Al₂O₃) layer when exposed to heat. This dense film acts as a shield against oxidation and scaling, making the alloy strip extremely stable in high-temperature environments. The molybdenum addition further enhances performance by improving creep resistance and strengthening the alloy under thermal stress.
