Pure Titanium Fiber Felt
Pure Titanium (Gr1/Gr2) Sintered Fiber Felt | High Porosity, Corrosion Resistant, Electrochemical Grade
Titanium fiber felt is a three-dimensional porous material made by non-woven web forming of pure titanium fibers, followed by high‑temperature vacuum diffusion sintering. It forms an interconnected fiber network without binders, delivering uniform pore distribution, high specific surface area, low flow resistance and robust fiber bonding. It is the preferred material for electrochemical and severe‑corrosion filtration applications.

Key Properties of Titanium felt
l Outstanding corrosion resistance in seawater, chlorides, strong acids/alkalis (passive TiO₂ film)
l High porosity (50%–80% standard; up to 90% custom), fully interconnected pores
l Excellent electrical/thermal conductivity, ideal for gas diffusion layers (GDL)
l High strength-to-weight ratio, flexible and durable, no loose fibers
l Biocompatible, non-magnetic
l Recommended service temperature: -200°C to 300°C (electrochemical); up to 600°C in inert atmosphere
Typical Applications of Titanium fiber felt
l PEM water electrolyzers & hydrogen production: Anode/cathode gas diffusion layers (GDL), flow field substrates
l Fuel Cells: Similar role as a gas diffusion layer in proton exchange membrane fuel cells (PEMFCs).
l Chemical & marine filtration: Seawater desalination, acid/alkali liquid filtration, catalyst support
l Medical & biotech: Implant materials, bioreactor membranes, sterile filters
l Aerospace & energy: Heat exchangers, lightweight porous structures, battery electrodes
l Electrochemical devices: Chlor-alkali cells, fuel cells, electrochemical sensors
