Metal fiber technology

Metal fibers are manufactured fibers composed of pure metals and metallic alloys which can be processed into textile products, porous media, plastic-coated metals, etc.
Discover the features and benefits that explain why metal fibers outperform alternative products in a wide range of applications.
Explore how Bekaert pushes the boundaries beyond metal fiber technology to enable new applications that contribute to a cleaner, safer, quieter and more comfortable world.
Bekaert pushes these boundaries in close collaboration with our customers and partners.
R&D and co-development is part of our DNA. That’s why we are the preferred supplier to critical applications in nuclear, semicon and aviation industry.

Key benefits of metal fiber products

Our engineered solutions are used worldwide in applications throughout a variety of industrial sectors. Examples include friction materials, catalyst substrates, composite reinforcement, cut-resistant gloves, heat pipes and sound attenuation.


Stainless steel and copper-steel fiber hybrids offer high design flexibility and a tunable, stable, wide range of electrical resistances.


Corrosion resistance

Metal fibers in alloys 316L, Fecralloy®, Inconel® 601 and Hastelloy® provide high-temperature corrosion resistance at the surface and in the underlying steel.


Fabrics incorporating fine metal fibers display outstanding stretchability and compressibility, hence are easily shaped, corrugated and pleated.

High ductility

Steel fibers display a high elongation at break. Therefore steel fiber reinforced composites enable high energy absorption on impact.

High permeability

Metallic fibers produce media with a high fraction of void space (up to 92% porosity), resulting in low pressure drops, high flow rates and high air permeability.

Mechanical strength

Metal fiber media is a binder-less, 3D network of metal fibers, featuring a metallurgical bond at all fiber contact points. The media maintains its integrity under high vibration and pressure.


Metal-based fabrics display a smooth, soft fiber surface that avoids scratches to glass during production, while their ductility results in low abrasiveness.

Thermal resistance

Metal fibers incorporating the alloys 304, 316L, Fecralloy®, Inconel® 601 and Hastelloy® offer high thermal resistance and excellent thermal conductivity.
