FeCrAl 0Cr21Al6 resistance wire delivers unmatched performance in high-temperature applications (up to 1250°C) with superior oxidation resistance. Ideal for industrial heaters, chemical reactors, and energy systems.
FeCrAl 0Cr21Al6 resistance wire is an advanced iron-chromium-aluminum alloy optimized for stability in aggressive thermal and chemical conditions. Comprising 21% chromium (Cr) and 6% aluminum (Al), this alloy develops a robust alumina (Al₂O₃) oxide layer when exposed to heat, ensuring exceptional resistance to oxidation, sulfidation, and chlorine-induced corrosion. With a service temperature range of 200°C to 1250°C, it outperforms conventional Ni-Cr alloys in prolonged high-heat scenarios, particularly in sulfur-rich or acidic atmospheres common in petrochemical and power generation industries.
The alloy’s low resistivity drift (1.40 μΩ·m at 20°C) guarantees consistent electrical performance, while its high tensile strength (≥600 MPa) and ductility allow seamless fabrication into coils, heating elements, and precision thermocouples. Compliant with ASTM B603, DIN 17471, and JIS C2520, FeCrAl 0Cr21Al6 is engineered for global adaptability—suitable for Middle Eastern oil refineries, Southeast Asian semiconductor plants, and European renewable energy systems. Its lightweight density (7.0 g/cm³) further enhances cost-efficiency in aerospace and automotive sensor applications.

Q1: How does FeCrAl 0Cr21Al6 compare to Kanthal alloys?
A: FeCrAl 0Cr21Al6 offers higher aluminum content for better oxidation resistance at lower costs, ideal for sulfur-rich or cyclic heating environments.
Q2: What is the recommended maximum operating temperature?
A: 1250°C in oxidizing atmospheres. For reducing environments (e.g., hydrogen-rich), limit to 1000°C to prevent embrittlement.
Q3: Can this wire be used in marine environments?
A: Yes, its high chromium content resists chloride-induced pitting, making it suitable for offshore platforms and desalination systems.
