FeCrAl Wire 0Cr21AI4 0Cr21AI6 0Cr23AI5 The Perfect Heating Solution for High-Temperature Industrial

Our FeCrAl wires—0Cr21Al4, 0Cr21Al6, and 0Cr23Al5—are total game-changers for high-temperature industrial heating, and we’re thrilled to show why they’re the go-to solution. These iron-chromium-aluminum alloys are built to deliver unbeatable performance in the toughest industrial environments, from furnaces to kilns.

Each grade brings something special to the table. 0Cr21Al4, with ~21% chromium and 4% aluminum, is super versatile, handling temperatures up to 1250°C with great formability for intricate heating elements. 0Cr21Al6 steps it up with 6% aluminum, pushing stability to 1300°C and offering a balance of strength and oxidation resistance. 0Cr23Al5, with 23% chromium and 5% aluminum, is the heavy hitter, reaching 1350°C and excelling in the most extreme heat conditions. All three form a protective Al2O3 oxide layer above 1000°C, making them champs at resisting oxidation and corrosion in sulfur-rich or acidic atmospheres.

With electrical resistivity ranging from 1.30 to 1.40 µΩ·m, these wires generate heat efficiently, perfect for industrial heating elements or resistors. Their tensile strength (~600-670 MPa) ensures durability, and their corrosion resistance holds up in harsh chemical or metallurgical settings. We can shape them into coils, strips, or custom forms, tailored for everything from ceramic kilns to metal heat-treating furnaces. The thermal conductivity (~11-13 W/mK) keeps heat distribution steady, ensuring consistent performance.

The industry in 2025 is all about resilience 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 turbine components, EV battery systems, or industrial ovens. Being 100% recyclable, they’re a perfect fit for eco-friendly manufacturing. As automation and high-efficiency heating systems keep trending, these wires’ stability and versatility make them a top pick for cutting-edge applications.

Sure, Nichrome Cr20Ni80 is great for lower-temperature setups and has slightly better formability, but our FeCrAl wires—especially 0Cr23Al5—outshine it in extreme heat and oxidation resistance. Just watch out for creep at max temperatures, though these wires handle most industrial conditions like pros.

From steel furnaces to aerospace heat treatment, our FeCrAl wires 0Cr21Al4, 0Cr21Al6, and 0Cr23Al5 deliver the heat resistance, reliability, and efficiency that keep high-temperature industries firing on all cylinders.
