1. Core Features of FeCrAl Fiber Felt

Our FeCrAl Fiber Felt is specially developed with high-quality FeCrAl alloy fibers (0Cr21Al6/0Cr25Al5) and advanced needling/sintering technology. Its core features perfectly match the strict requirements of high-temperature industrial applications, and it is far superior to ordinary metal fiber felt in high-temperature performance:

• Ultra-High Temperature Resistance: FeCrAl alloy fibers contain high content of chromium and aluminum, which can form a dense and stable aluminum oxide protective layer on the surface at high temperatures, enabling the FeCrAl Fiber Felt to withstand long-term use at 900-1100℃ and short-term high temperature up to 1200℃, and even reach a high scaling temperature of 1425℃[2][4]. It can stably operate in ultra-high temperature environments such as industrial furnaces, high-temperature tempering furnaces and waste incineration equipment without embrittlement, deformation or fiber shedding, ensuring long-term service life[2][5].

• Excellent Oxidation & Sulfidation Resistance: The unique alloy composition of FeCrAl gives the fiber felt outstanding oxidation resistance and sulfidation resistance[2][4]. It can resist oxidation and corrosion in high-temperature air, flue gas and corrosive industrial atmospheres, and will not rust or degrade even after long-term use in harsh environments, which is suitable for high-temperature filtration and metallurgical processing scenarios[5][11].

• High Strength & Thermal Shock Resistance: The fibers are tightly entangled through needling process or fused into a whole through high-temperature sintering, forming a stable three-dimensional network structure[2][5]. It has high tensile strength, wear resistance and pressure resistance, and can withstand mechanical impact, continuous friction and high-temperature thermal shock. It can adapt to repeated heating and cooling cycles without performance degradation, and has good form stability and aging resistance[4][11].

• Soft Texture & Scratch-Proof Performance: The needled FeCrAl Fiber Felt has a soft and delicate surface, no burrs, and excellent flexibility[6]. It can form a soft buffer layer between the product and the equipment, avoiding scratches and damage to the product surface. It is especially suitable for high-temperature bending, tempering and conveying links of automotive glass, as well as high-temperature protection of precision components[11].

• High Filtration Precision & Permeability: The sintered FeCrAl Fiber Felt has a uniform porous structure with controllable pore size (1-100μm) and high porosity (65%-88%)[8][11]. It has excellent high-temperature filtration performance, which can effectively trap solid particles and impurities in high-temperature gases, with low pressure loss and large flow rate, making it ideal for high-temperature gas dust collection and exhaust gas filtration[2][6].

• Customizable Versatility & Reusability: We can customize the thickness, density, pore size, size and process (needled/sintered) of the FeCrAl Fiber Felt according to customer needs[3][8]. It can be processed into sheets, rolls, roller covers, filter elements and other finished products. At the same time, it can be cleaned and reused through high-temperature cleaning and ultrasonic cleaning, which is environmentally friendly and cost-effective[2][6].

2. Regular Specifications and Parameters

We adopt standardized production processes and strict quality control (passing ISO 9001, ISO 14001 and SGS certifications[1][7][8]) to ensure the consistency and stability of product specifications. The following are the regular specifications and parameters of FeCrAl Fiber Felt, which can be fully customized according to customer actual production needs and application scenarios:

Note: The above are regular specifications. We can adjust parameters such as thickness (0.25-15mm), width (up to 2000mm), density (0.4-1.0g/cm³), fiber diameter (15-80μm) and pore size (0.1-500μm) according to your specific application requirements[4][8]. The product can be supplied in rolls (5-10 meters/roll) or cut into sheets (500×500mm, 1000×1000mm, etc.), and can also be customized into filter elements, roller covers and other special-shaped products to perfectly fit your production equipment and application scenarios[4][6]. The minimum order quantity can be 10 pieces or 10㎡, and the supply capacity can reach 50000㎡ per month[1][8].

3. Key Applications of FeCrAl Fiber Felt

Our FeCrAl Fiber Felt has excellent high-temperature resistance and comprehensive performance, and is widely used in various high-temperature industrial fields, providing targeted solutions for different application scenarios:

3.1 Automotive Glass Production Industry

As a core supporting material for high-temperature links in automotive glass production, FeCrAl Fiber Felt is mainly used in heating, bending and tempering links. Its ultra-high temperature resistance (up to 1100℃) can adapt to the high temperature of automotive glass tempering furnaces, and it is used for roller covering and mold wrapping[11]. The soft texture of the needled FeCrAl Fiber Felt can avoid scratches and indentations on the surface of high-temperature glass blanks, ensuring the forming precision and optical quality of automotive windshields and side windows. It also can isolate high temperature from eroding the roller body, extending the service life of equipment and improving the qualification rate of finished products[11].

3.2 High-Temperature Filtration & Environmental Protection Industry

In the high-temperature filtration and environmental protection field, sintered FeCrAl Fiber Felt is widely used for high-temperature gas dust collection, waste incineration dust removal, power plant flue gas filtration, automotive exhaust gas treatment and diesel particulate filtration (DPF)[2][11]. Its high-temperature resistance and filtration precision can effectively remove harmful particles and pollutants in high-temperature flue gas, meet global environmental protection standards, and it can be cleaned and reused, reducing environmental protection costs[2][6].
