Overview
Micron-scale metal fiber produced by bundle drawing, from 1 to 100 µm in stainless steel, FeCrAl, nickel, titanium, copper, tantalum and Hastelloy. The fiber keeps the thermal, electrical and corrosion behaviour of the parent metal while adding textile-like flexibility and high specific surface area — the base material for every downstream product.
Alloys and Specifications
| Alloy | Typical diameter | Key properties | Typical use |
|---|---|---|---|
| Stainless steel | 1–100 µm | Thermal conductivity, corrosion resistance, flexibility, high surface area | Felt substrate, blended yarn, fabrics |
| FeCrAl | 8–40 µm | High resistivity, low temperature coefficient, oxidation resistance, higher service temperature | Hot-gas filtration, burners, particulate filters |
| Nickel | On request | High tensile strength, good flexibility | Alkaline duty, electrode substrates |
| Titanium | On request | Light, strong, highly corrosion resistant | Fuel cells, electrolysis, medical |
| Copper | On request | High electrical and thermal conductivity, tunable catalysis, soft | Conduction, heat transfer, catalysis |
| Hastelloy | On request | High corrosion resistance (C276, C59) | Filtration in aggressive media |
| Tantalum | On request | Resists strong acids | Severe chemical duty |
Supply Forms
- Continuous fiber — single or multi-strand, filament count and diameter to order
- Chopped fiber — cut to length, good dispersion, for coatings and plastics
- Stretch-broken tow — 38–110 mm, 2–10 g/m, good bulk and processability
- Blended tow — with polyester, aramid or PPS; roughly 10% addition gives permanent anti-static performance
Capacity and Delivery
More than 500 t of metal fiber per year. [To be confirmed: MOQ, sampling lead time, production lead time, packaging]
