Premium 0Cr20Al5 FeCrAl Alloy (DIN 1.4767) | High-Temp Heating Wire for Industrial & Consumer Applications
0Cr20Al5 is a premium iron-chromium-aluminum (FeCrAl) alloy engineered for extreme thermal environments. Characterized by exceptionally high electrical resistivity, low temperature coefficient of resistance (TCR), and outstanding oxidation resistance, it operates continuously at temperatures up to 1300°C (2372°F). Ideal for applications demanding rapid heat cycles and long-term stability, this alloy outperforms conventional materials in efficiency and durability.
Key Technical Advantages
Unmatched Thermal Performance
- Max Operating Temp: 1300°C (continuous) / 1400°C (intermittent)
- Low TCR (0.00005/°C): Ensures stable resistance across temperature fluctuations.
Superior Material Properties
- Self-Protecting Oxide Layer: Forms dense α-Al2O3 scale at high temperatures, preventing further oxidation.
- Sulfur & Carbon Resistance: Withstands corrosive atmospheres better than nickel-chromium alloys.
- Low Density (7.2 g/cm³): Reduces component weight vs. Ni-Cr alternatives.
Economic Efficiency
- 30-40% lower cost than NiCr alloys (e.g., Nichrome) with comparable performance.
