Bright Annealed Soft FeCrAl Alloy 0Cr21Al6 0Cr25Al5 0Cr23Al5 0Cr21Al6Nb Heating Resistance Wire

Our bright annealed soft FeCrAl alloy wires—0Cr21Al6, 0Cr25Al5, 0Cr23Al5, and 0Cr21Al6Nb—are total standouts for high-temperature heating, and we’re pumped to share why they’re perfect for your next project. These iron-chromium-aluminum alloys are engineered to deliver top-notch performance in extreme heat, with a sleek, polished finish that screams quality.

Each grade has its own superpower. 0Cr21Al6, with ~21% chromium and 6% aluminum, is super formable and stable up to 1300°C, ideal for intricate heating elements. 0Cr25Al5, with ~25% chromium and 5% aluminum, pushes the limit to 1350°C, making it a beast for the hottest kilns and furnaces. 0Cr23Al5, with ~23% chromium and 5% aluminum, offers a great balance of heat resistance and cost, also hitting 1300°C. 0Cr21Al6Nb, with niobium added, matches 1300°C but brings extra creep resistance for long-term durability under stress. All form a protective Al2O3 oxide layer above 1000°C, giving them killer oxidation resistance in sulfur-rich or acidic atmospheres.

The bright annealed finish isn’t just for looks—it boosts corrosion resistance by removing surface impurities, making these wires thrive in harsh chemical or humid environments. With electrical resistivity ranging from 1.35 to 1.42 µΩ·m, they generate heat efficiently, perfect for heating elements in furnaces, ovens, or resistors. The annealing process makes them soft and flexible, with tensile strength (~650-680 MPa) ensuring durability while allowing easy shaping into coils or custom forms. Thermal conductivity (~11-12 W/mK) keeps heat distribution steady for reliable performance.

The industry in 2025 is all about precision and sustainability, and our FeCrAl wires are right on trend. There’s huge demand for high-temperature, corrosion-resistant materials in aerospace, automotive, and energy sectors, like EV battery systems, turbine heat treatment, or ceramic kilns. Being 100% recyclable, they’re a perfect fit for eco-friendly manufacturing. As automated, high-efficiency heating systems keep trending, these wires’ formability and heat stability make them a top pick for innovative designs.

Sure, Nichrome Cr20Ni80 is awesome for lower-temperature setups (up to 1200°C) and a bit more formable, but our FeCrAl wires, especially 0Cr25Al5, outshine it in extreme heat and oxidation resistance. Just watch out for creep at max temps, though these wires handle most industrial conditions like champs.

From industrial furnaces to precision heating elements, our bright annealed soft FeCrAl alloy wires deliver the heat resistance, flexibility, and reliability that keep your high-temperature applications running hot and strong.
