Titanium Fiber Felt: Lightweight, Corrosion-Resistant Porous Metal Media
Titanium fiber felt is a nonwoven porous material made from pure titanium fibers through a process of needle-punching and high-temperature sintering. Known for its exceptional corrosion resistance, biocompatibility, and structural integrity, titanium fiber felt is widely used in advanced filtration, energy systems, and biomedical devices.
Key Features
Excellent Corrosion Resistance: Titanium naturally forms a stable oxide layer, offering outstanding resistance to acids, alkalis, and seawater environments.
High Porosity and Surface Area: Typically 70%–90% porosity, ideal for filtration, electrode scaffolding, and gas diffusion applications.
Mechanical Strength & Formability: Maintains structural integrity under pressure; can be rolled, welded, or shaped without cracking.
High-Temperature Stability: Operational up to 500–600°C in inert or mildly oxidative environments.
Biocompatibility: Non-toxic and suitable for medical implantables, such as bone scaffolds or tissue engineering.
Typical Applications
Electrodes for PEM Electrolyzers & Fuel Cells: As a gas diffusion layer (GDL) or porous transport layer (PTL) for proton exchange membrane (PEM) water electrolysis and hydrogen fuel cells.
Battery Current Collectors: Used in solid-state and lithium-metal battery architectures.
Biomedical Implants: Structural support in dental and orthopedic implants, tissue scaffolds.
Precision Filtration: Fine filtration of aggressive chemical or high-purity fluid systems.
Heat Exchangers: Lightweight, corrosion-resistant alternatives to metal foams.
