FeCrAl Heating Elements

About FeCrAl Heating Elements

FeCrAl Alloy Heating Elements (Iron-Chromium-Aluminum) have high-temperature resistance, cost-effectiveness, and excellent oxidation resistance. We supply complete specifications of FeCrAl Alloy Heating Elements with reliable quality. Below is a detailed breakdown of FeCrAl Alloy heating elements, including their advantages, disadvantages, applications.

1. FeCrAlloy Grades for Heating Elements:

2. FeCrAl Alloy Heating Element Types:

• Wire Heating Elements

• Form: Round or flattened wires (common diameters: 0.5mm–5mm).
• Applications:
  • Small appliances (toasters, hair dryers).
  • Industrial furnaces (coiled or straight).
  • Vaping coils (Kanthal A-1).
• Advantages:
  • Easy to shape into coils or spirals.
  • Uniform heating due to consistent cross-section.

(2) Ribbon/Strip Heating Elements

• Form: Thin, flat strips (e.g., 1mm–3mm thick, 5mm–50mm wide).
• Applications:
  • Surface heaters (industrial ovens, food warmers).
  • High-wattage radiant heaters.
• Advantages:
  • Larger surface area → better heat radiation.
  • Can handle higher power loads than wire.

(3) Mesh Heating Elements

• Form: Woven FeCrAl wire grids.
• Applications:
  • Infrared heaters.
  • Conveyor belt dryers.
• Advantages:
  • Rapid heating & cooling.
  • Even heat distribution.

3. Typical Applications of FeCrAl Heating Elements:

– Industrial Furnaces (highest temp resistance) 

– Electric Kilns & Ceramic Heaters 

– Household Appliances (toasters, ovens, hair dryers) 

– Vaping Coils & E-Cigarettes (Kanthal A-1 is popular) 

4. Design Considerations for FeCrAl Heating Elements:

 Wire Gauge & Shape 

– Thinner wires heat up faster but have shorter lifespans. 

– Ribbon/Strip elements provide more surface area for radiant heating. 

 Power Requirements 

– FeCrAl’s higher resistivity allows for shorter, thicker wires compared to Nichrome. 

 Mounting & Support 

– Avoid mechanical stress (FeCrAl becomes brittle at high temps). 

– Use ceramic insulators for high-temp applications.

5. Lifespan & Failure Modes

✔ Longevity: Properly used FeCrAl elements last years in industrial settings. 

❌ Common Failures: 

– Thermal cycling fatigue (repeated heating/cooling causes cracks). 

– Contamination (sulfur, carbon reduce lifespan). 

– Mechanical damage (bending after heating).
