Porous Titanium Materials offering lightweight strength and corrosion resistance for structural and biomedical engineering applications

Titanium fiber felt, also known as titanium sintered felt or titanium felt, is a porous metal material made from fine titanium fibers through fiber laying, forming, and high-temperature vacuum sintering. The sintered titanium fiber structure forms a stable three-dimensional interconnected porous network, providing excellent corrosion resistance, electrical conductivity, gas-liquid permeability, and mechanical stability.

Titanium fiber felt is widely used in PEM water electrolysis, hydrogen fuel cells, gas diffusion layers, porous transport layers, electrochemical devices, filtration systems, and other new energy applications. Compared with titanium mesh and titanium powder sintered plates, titanium fiber felt offers higher porosity, larger specific surface area, and more uniform flow distribution.

Titanium fiber felt has a stable porous structure and excellent performance in electrochemical environments. Its interconnected pores allow efficient gas and liquid transport, while the titanium material provides strong corrosion resistance in acidic, oxidative, and high-humidity working conditions.

• High porosity
• Uniform pore distribution
• Excellent corrosion resistance
• Good electrical conductivity
• Stable gas and liquid permeability
• Strong sintered fiber structure
• Low contact resistance
• Good mechanical support performance
• Customizable thickness, size, porosity, and shape
• Surface treatment or coating can also be provided according to different application requirements

In PEM water electrolysis, titanium fiber felt can be used as a porous transport layer or gas diffusion layer. It helps distribute water, transport oxygen, conduct electrons, and support the membrane electrode assembly. Titanium is especially suitable for the anode side of PEM water electrolysis because of its corrosion resistance in acidic and oxidative environments.

In hydrogen fuel cell systems, titanium sintered felt can be used as a gas diffusion layer or support layer. Its porous structure helps improve gas distribution, water management, current collection, and mechanical support.

Titanium felt can also be used in electrochemical reactors, electrolysis systems, electrosynthesis, electroplating, flow batteries, and other systems requiring corrosion-resistant conductive porous materials. With its stable porous structure and good permeability, titanium fiber felt is also suitable for gas-liquid diffusion, high-end filtration, catalyst support, and special industrial filtration applications.
