FeCrAl Mesh

Product Description:

FeCrAl mesh is a woven wire mesh made from Iron-Chromium-Aluminum (FeCrAl) alloys, known for their exceptional high-temperature oxidation resistance, corrosion resistance, and electrical heating properties. It is available in different grades such as 0Cr25Al5, 0Cr23Al5, Kanthal D, Kanthal A-1, Kanthal APM, etc.

 Key Properties of FeCrAl Mesh: 

1. Material Composition:

– Iron (Fe): Base metal (~70-80%) 

– Chromium (Cr): 15-22% (enhances oxidation resistance) 

– Aluminum (Al): 4-7% (forms a protective alumina scale at high temps) 

– Minor Elements: Yttrium (Y), Rare Earths (for improved scale adhesion) 

2. Temperature Resistance:

– Continuous Use: Up to 1300°C (2372°F) 

– Short-Term Exposure: Up to 1400°C (2552°F) 

– Forms a protective Al₂O₃ (alumina) layer at high temps, preventing further oxidation 

3. Corrosion & Oxidation Resistance:

– Excellent resistance to oxidizing atmospheres, sulfur, and carburizing environments 

– Performs better than stainless steel (304, 310) in high-temperature applications 

– Resists thermal cycling and thermal shock 

 Common FeCrAl Mesh Specifications: 

Applications of FeCrAl Mesh: 

✔ Industrial Furnaces (heat treatment, sintering, annealing) 

✔ Electric Heating Elements (ovens, toasters, industrial heaters) 

✔ Automotive Exhaust Systems (catalytic converter supports) 

✔ Gas Burners & Flame Arrestors 

✔ High-Temperature Filtration (hot gas filtration in power plants) 

 Comparison with Other Alloys: 

★ FeCrAl is better for extreme oxidation & heating, while Inconel is better for corrosion resistance.
