FeCrAl Cr21Al4/FCHW-2 High-Temperature Resistance Alloy Wire – Durable Heating Element for Industrial & Lab Applications

 

Material Overview:

  • Alloy Type: FeCrAl (Iron-Chromium-Aluminum) alloy, standardized as Cr21Al4 or FCHW-2.
  • Chemical Composition:
    • Chromium (Cr): 21%
    • Aluminum (Al): 4%
    • Iron (Fe): Balance (with trace impurities ≤0.15% C, ≤1.0% Mn, ≤1.0% Si).
  • Standards Compliance:
    • DIN 17470 (Germany)
    • ASTM A580 (USA)
    • ISO 9001:2015 certified manufacturing.

Key Features & Performance:

  1. High-Temperature Resistance:
    • Operates continuously up to 1250°C (2282°F).
    • Short-term peak temperatures up to 1350°C without structural degradation.
  2. Oxidation & Corrosion Resistance:
    • Forms a stable Al2O3 + Cr2O3 oxide layer at high temperatures, preventing rust and chemical attack in oxidizing environments (e.g., air, water vapor, sulfur-rich gases).
  3. Electrical Resistivity:
    • 1.50 μΩ·m at 20°C, ensuring efficient heat generation with minimal energy loss.
  4. Low Thermal Drift:
    • Maintains ±1.5% resistance stability from 20°C to 1100°C, ideal for precision heating systems.
  5. Mechanical Strength:
    • Tensile Strength: ≥600 MPa
    • Elongation: ≥18% (ASTM E8 tested)

Applications:

  • Industrial Heating Systems:
    • Electric furnaces for metal heat treatment, glass melting, and ceramic sintering.
    • Industrial ovens for coating, drying, and curing processes.
  • Laboratory Equipment:
    • High-temperature test chambers, calibration furnaces, and sample heating devices.
  • Specialized Use Cases:
    • Automotive Exhaust Systems: Preheating catalysts in emission control units.
    • 3D Printer Beds: Custom high-temperature heating elements for industrial-grade printers.
    • Semiconductor Manufacturing: Annealing and wafer heating in controlled environments.
