0Cr23AI5 0Cr25AI5 0Cr21AI6Nb FeCrAl Wire The Perfect Heating Wire for High-Temperature Applications

Our 0Cr23Al5, 0Cr25Al5, and 0Cr21Al6Nb FeCrAl wires are absolute powerhouses for high-temperature heating, and we’re thrilled to show why they’re the perfect fit for industrial applications. These iron-chromium-aluminum alloys are designed to deliver top-notch performance in the hottest, toughest environments, from furnaces to precision heating systems.

Each grade brings its own strengths. 0Cr23Al5, with ~23% chromium and 5% aluminum, is a solid all-rounder, stable up to 1300°C with great oxidation resistance. 0Cr25Al5, with ~25% chromium and 5% aluminum, pushes the limit to 1350°C, making it a champ for the most extreme heat applications. 0Cr21Al6Nb, with ~21% chromium, 6% aluminum, and niobium, hits 1300°C and adds extra creep resistance and strength thanks to the niobium boost. All three form a protective Al2O3 oxide layer above 1000°C, shielding them from degradation in sulfur-rich or acidic atmospheres.

With electrical resistivity ranging from 1.35 to 1.40 µΩ·m, these wires generate heat efficiently, perfect for heating elements, resistors, or industrial kilns. Their corrosion resistance is killer, holding up in chemical plants or humid environments. Tensile strength (~650-680 MPa) ensures durability, with 0Cr21Al6Nb offering a slight edge due to niobium. We can shape them into coils, strips, or custom forms, and their thermal conductivity (~11-12 W/mK) keeps heat distribution steady for reliable performance.

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

Sure, Nichrome Cr20Ni80 is great for lower-temperature applications 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 pros.

From industrial furnaces to high-temp precision heaters, our 0Cr23Al5, 0Cr25Al5, and 0Cr21Al6Nb FeCrAl wires deliver the heat resistance, reliability, and efficiency that keep industries running hot and strong.
