FeCrAl woven wire mesh is engineered from a high-performance iron-chromium-aluminum alloy, offering exceptional thermal stability, oxidation resistance, and longevity. It’s specifically designed to withstand continuous operation at elevated temperatures, making it a reliable choice for industries such as metallurgy, ceramics, and heat treatment.
This mesh is highly regarded in the manufacturing of electric heating elements for furnaces and kilns, as its material composition allows it to maintain mechanical integrity even at temperatures exceeding 1200°C. Unlike stainless steel, FeCrAl woven wire mesh has superior resistance to scaling and surface degradation under extreme oxidation conditions.
Another notable benefit is its lower density and high electrical resistivity, which enable efficient energy usage and longer service cycles. The woven structure ensures uniform current distribution and consistent heat transfer, improving performance in applications like air heaters, infrared emitters, and catalytic gas combustion systems.
Available in various mesh sizes and wire diameters, this material can be customized to meet specific operational demands. Whether used for thermal shielding, filtration in corrosive environments, or direct heating applications, FeCrAl mesh proves to be a durable and cost-effective solution.
When dealing with intense heat and harsh oxidation, FeCrAl woven wire mesh delivers unmatched performance. This material, an alloy of iron (Fe), chromium (Cr), and aluminum (Al), is well known for its high-temperature tolerance and remarkable resistance to corrosion and chemical degradation.
In industrial environments such as chemical reactors, high-temperature filters, and thermal insulation, FeCrAl woven wire mesh outperforms traditional alloys. The aluminum in the alloy forms a protective oxide layer when heated, shielding the surface from oxidation and extending the lifespan of the mesh.
Its excellent thermal conductivity and stable resistance properties make it ideal for use in industrial electric furnaces, radiant heaters, and as a support structure for catalytic systems. Additionally, it’s suitable for gas heating and heat-treating furnaces where consistent heat distribution is critical.
The mesh can be woven into various densities, allowing precise control of airflow, heat flow, or particle filtration. It's lightweight, easy to shape, and can be manufactured in rolls, sheets, or custom-cut formats to suit unique equipment needs.
Whether for thermal management or structural support in heating devices, FeCrAl woven wire mesh provides engineers with a high-performance material they can trust in the most demanding conditions.
