Porosity Titanium Fiber Sintered Felt

Engineered with a multilayer 3D titanium fiber matrix, this sintered felt achieves a tunable porosity (75–90%) while retaining exceptional mechanical strength, combining the lightweight advantages of titanium alloys with robust filtration performance. The open-cell structure enables depth gradient filtration, capturing particles as fine as 1–10μm across its cross-sectional layers. Unlike stainless steel, titanium’s innate corrosion immunity excels in chloride-rich, acidic/alkaline, and oxidizing environments (e.g., seawater, HCl, HNO₃), withstanding temperatures up to 400°C (752°F) without degradation. Its high surface-to-volume ratio grants 2–3x higher contaminant retention capacity than traditional metal meshes, significantly reducing maintenance frequency. The material’s biocompatibility (meets ASTM F136/ISO 5832-11) and non-toxicity make it ideal for sterile processes, while its weldability and ductility support seamless fabrication into discs, tubes, or custom geometries.
