FeCrAl wire mesh is primarily composed of an alloy of iron (Fe), chromium (Cr), and aluminum (Al), commonly referred to as FeCrAl. The chromium and aluminum content typically ranges between 5% and 25%, with specific ratios adjusted according to application requirements and product specifications. This unique alloy composition endows the material with exceptional oxidation resistance and thermal endurance at high temperatures, making it particularly suitable for operational environments exceeding 1000°C.
The mesh count (number of holes per linear inch) of FeCrAl wire mesh can be customized according to requirements. Typically, the standard range spans from 1 mesh to 100 mesh. Lower mesh count variants feature larger apertures, making them suitable for coarse filtration or heating element applications. Higher mesh count versions are engineered for precision filtration, effectively intercepting microscopic particles.
FeCrAl wire mesh production primarily involves wire drawing, weaving, and welding procedures. Initially, iron-chromium-aluminum alloy wires are produced through smelting with specific alloy compositions. Subsequently, the alloy wires undergo a wire drawing process to achieve finer diameters. These drawn wires are then woven or welded into mesh configurations according to design specifications16. Finally, the mesh may undergo annealing treatment to enhance its high-temperature resistance and oxidation stability.

Applications Of Fecral Wire Mesh
FeCrAl wire mesh serves critical functions across multiple industrial domains due to its exceptional high-temperature resilience and oxidation resistance:
Heating Elements: Widely deployed in electric furnaces, industrial ovens, and convective heating systems (e.g., hot air blowers) where sustained operation above 1000°C is required.
High-Temperature Filtration: Utilized in metallurgical and chemical processing for filtering particulate matter from gases/liquids, handling aggressive media under extreme thermal conditions.
Heat Exchangers: Integrated as core components in thermal management systems, maintaining structural stability and heat transfer efficiency in industrial heat treatment equipment.
Electromagnetic Shielding: Employed in electronic enclosures to mitigate electromagnetic interference (EMI), leveraging its conductive alloy properties.
