Our High-Temperature 0Cr21Al6 FeCrAl Kiln Bar is a game-changer for industries needing reliable, high-performance heating solutions. Made from an iron-chromium-aluminum alloy, this kiln bar packs 21% chromium and 6% aluminum, with iron as the backbone. This combo delivers top-notch resistance to oxidation and corrosion, even when the heat’s cranked up to 1350°C (2462°F). The secret sauce? A protective aluminum oxide (Al₂O₃) layer that forms at high temperatures, keeping the bar safe from wear and tear in harsh environments.
We’ve designed this kiln bar to shine in demanding settings like industrial kilns, heat treatment furnaces, and ceramic processing lines. Its high electrical resistivity—around 1.45 μΩ·m—makes it perfect for heating elements that need to stay efficient and stable. Plus, it’s got solid mechanical strength (630-780 MPa tensile strength) and can handle cyclic heating without breaking a sweat. Whether you need bars, strips, or wires, we can customize the 0Cr21Al6 to fit your exact specs, ensuring it slots right into your thermal processing setup.
What sets our kiln bar apart is its balance of performance and cost. It’s a high-value option that delivers premium-grade results without the premium-grade price tag. From small-scale ceramic kilns to massive industrial furnaces, this alloy keeps things running smoothly, saving you downtime and maintenance costs.

The industrial heating sector is heating up—pun intended. With global demand for ceramics, glass, and metals on the rise, kilns and furnaces are working overtime. The FeCrAl alloy market, including our 0Cr21Al6 Kiln Bar, is seeing steady growth, driven by industries like metallurgy, aerospace, and chemical processing. According to recent trends, the global market for high-temperature alloys is projected to grow at a CAGR of around 4-5% through 2030, fueled by advancements in manufacturing and energy efficiency.
One big driver is the push for sustainability. Industries are under pressure to cut energy use and emissions, and that’s where efficient heating elements like our 0Cr21Al6 come in. Its high resistivity and durability mean less energy waste and fewer replacements, aligning with eco-friendly goals. Plus, the rise of automation and smart manufacturing is boosting demand for reliable, long-lasting components that can handle extreme conditions without constant upkeep.
Another trend is customization. Companies aren’t just looking for off-the-shelf solutions anymore—they want tailored components that fit their specific kilns or processes. We’ve seen this in ceramics, where precise temperature control is critical, and in metallurgy, where high-heat consistency is non-negotiable. Our ability to deliver custom shapes and sizes gives us a leg up in meeting these needs.
On the flip side, the industry faces challenges like raw material price volatility. Chromium and aluminum costs can fluctuate, impacting alloy production. But we’ve optimized our supply chain to keep costs stable, ensuring our 0Cr21Al6 Kiln Bar remains competitively priced. Competition is fierce, too, with alternative alloys like nichrome ( Cr20Ni80 ) vying for market share. While nichrome has its strengths, our FeCrAl alloy offers better oxidation resistance at a lower cost, making it a go-to for kiln applications.

Our 0Cr21Al6 FeCrAl Kiln Bar is a workhorse across multiple industries, thanks to its versatility and high-temperature prowess. Here’s where it shines:
Ceramics Industry: Used in kiln heating elements for firing pottery, tiles, and advanced ceramics. Its ability to withstand 1350°C ensures consistent, high-quality output.
Metallurgy: Perfect for heat treatment furnaces, where it supports processes like annealing and sintering. The bar’s creep resistance keeps it stable during long, high-heat cycles.
Glass Manufacturing: Helps maintain precise temperatures in glass-melting kilns, ensuring smooth production of everything from flat glass to specialty products.
Chemical Processing: Used in reactors and heat exchangers handling corrosive gases or liquids. The Al₂O₃ layer protects against chemical degradation.
Energy Sector: Found in boiler components and gas turbine parts, where it tackles high-temperature oxidation and thermal fatigue.
Household Appliances: Powers heating elements in high-end ovens and water heaters, delivering reliable performance for consumers.
Its magnetic properties (up to 600°C) and thermal conductivity (around 46.1 KJ/m·h·°C) make it adaptable to both industrial and domestic uses. Plus, its low coefficient of thermal expansion (14.7 x 10⁻⁶/°C) means it won’t warp under heat stress, ensuring long-term reliability.
When it comes to high-temperature kiln bars, we know you’ve got options. But here’s why our 0Cr21Al6 FeCrAl Kiln Bar stands out. Unlike some competitors who focus on generic alloys, we specialize in tailoring our products to your exact needs. Need a specific bar length or diameter? We’ve got you covered with custom fabrication that ensures a perfect fit for your kiln. Our manufacturing process uses advanced techniques like vacuum smelting to boost alloy purity, which translates to better performance and longer lifespan.
We also prioritize cost-efficiency. While some companies push pricier alloys with fancy additives, our 0Cr21Al6 delivers top-tier oxidation resistance and durability at a fraction of the cost—think $18-28/kg compared to $28-50/kg for premium grades. This makes it a smart pick for businesses looking to optimize budgets without skimping on quality.
Our supply chain is another edge. We’ve streamlined sourcing and production to dodge the raw material price swings that plague the industry. This means stable pricing and faster delivery times, so you’re not left waiting when your kiln needs a replacement.
