FeCrAl Alloy
FeCrAl resistance wire is a heating alloy made mainly from iron (Fe), chromium (Cr), and aluminum (Al). It reliably converts electrical energy into heat through resistance and is designed for long-term use in high-temperature air environments.
- √ Continuous operating temp: 1000–1400°C
- √ Gets long-term oxidation protection from an Al₂O₃ layer
- √ Iron-based, so it’s way more affordable than NiCr
- × Not good for sulfur-rich, strongly reducing, or high-hydrogen environments
If your setup runs hot for extended periods in regular air, FeCrAl is usually the better choice.
FeCrAl Alloy Wire Manufacturer and Supplier In China
FeCrAl resistance wire builds a tight, stable aluminum oxide layer (Al₂O₃) at high heat, keeping oxidation super slow over long runs. That’s why it’s awesome for non-stop, long-cycle, high-temp setups. Unlike the Cr₂O₃ layer from NiCr, Al₂O₃ is tougher and denser—the real reason FeCrAl lasts way longer in air above 1000°C.
With killer high-temp tolerance, top oxidation resistance, and long life, FeCrAl wire is all over industrial kilns, heat treatment gear, lab heaters, and always-on industrial heating systems.
For industrial folks who put stability, life, and manageable upkeep first, FeCrAl is a proven, dependable pick.
CVSIC FeCrAl Resistance Wire Standouts
FeCrAl alloys are made for long energized runs at high heat without failing, oxidizing fast, or unpredictable life.
It’s not about quick stuff—it’s built for steady long-haul service at crazy temps.
Engineering Breakdown
- Iron base → Tough structure, keeps costs down—ideal for huge industrial heating
- High chrome → Basic oxidation protection
- Aluminum’s the star → Builds that dense Al₂O₃ layer at heat, the real life extender
- Self-healing layer → Fixes local damage, reforms protection
- High resistivity → Shorter wire for same power, tighter designs
- No fancy metals → Big cost win in high-power hot furnaces
Standouts
- Steady runs in 1200–1400°C range long-term
- Crazy low oxidation at heat—outlasts NiCr by miles
- Stable layer doesn’t mess with resistance—predictable performance
- Perfect for always-on jobs (industrial furnaces, heat treat ovens)
- Holds strength hot—no easy sag
- Not for lots of on-off—better for “flip on and forget” systems
- Custom sizes, resistance, power—whatever you need

When NOT to Pick FeCrAl
Choosing an unsuitable material is not due to product deficiency, but rather to misapplication.
| Material | Temp Range | Suitable Atmospheres | Cost | Key Limitations / Notes |
|---|---|---|---|---|
| FeCrAl | 1000–1400°C | Air or oxygen-rich | Low | Weak in sulfur-containing or reducing atmospheres |
| NiCr | 800–1200°C | Most corrosive environments | Moderate to high | Shorter lifespan at very high temps |
| MoSi2 | 1200–1800°C | Air | High | Very brittle with high cost |
| SiC | Above 1400°C | Varies by type/structure | High | Very sensitive to thermal shock |
In those cases, NiCr, MoSi2, or SiC are safer alternatives.
Applications for FeCrAl Resistance Wire
- Industrial kilns: Box, bogie, roller hearth—handles constant high heat.
- Heat treatment systems: Steady heat for annealing, normalizing, and tempering.
- Lab heaters: Great for test furnaces needing precise, stable temps.
