Products Description
Need a corrosion-resistant, high-purity filter for aggressive chemical or pharmaceutical applications?
Guanjiang's Titanium Alloy Sintered Filter is an advanced porous filtration medium manufactured through powder metallurgy processes. Using high-purity titanium powder, the technology involves precise grading, mold forming, and vacuum sintering at 1200-1400°C to create a three-dimensional porous structure with interconnected pores and controlled permeability. Offering filtration precision from 0.1 to 100μm, porosity of 30-50%, and compressive strength ≥5 MPa, this filter excels in chemical processing, pharmaceutical, and marine applications.
Key Advantages
Withstands chlorine ions, seawater, and various acids/alkalis. Exceptional durability in chemical processing and marine applications — significantly outlasts stainless steel filters in corrosive media.
Maintains structural integrity at elevated temperatures. High strength-to-weight ratio (density: 4.5 g/cm³). Excellent thermal stability and shock resistance.
Uniform pore distribution ensures consistent filtration performance. Regenerable through backflushing, chemical cleaning, or thermal treatment. Low pressure drop with high dirt holding capacity.
100% titanium construction eliminates secondary contamination. Meets FDA, USP Class VI, and ASTM F2888 standards. Suitable for pharmaceutical and food grade applications.
High compressive strength prevents structural collapse under pressure differentials.
Controlled porosity optimizes flow rate while maintaining filtration efficiency.
Precision grading, mold forming, and vacuum sintering at 1200-1400°C.

Frequently Asked Questions
Q1: What makes titanium sintered filters better than stainless steel filters?
A: Titanium offers superior corrosion resistance — especially against chlorides, seawater, and acidic media where stainless steel (304/316L) can pit or crack. Titanium is also biocompatible (no nickel leaching), lighter (60% density of steel), and maintains strength at higher temperatures. For aggressive chemical or pharmaceutical applications, titanium is the preferred material.
Q2: How do you clean and regenerate the titanium sintered filter?
A: The filter can be regenerated through multiple methods: Backflushing (reverse flow of clean fluid), Ultrasonic cleaning (in suitable solvent), Chemical regeneration (dissolving trapped particles), or Thermal treatment (burning off organic residues). Proper regeneration significantly extends service life compared to disposable filters.
Q3: What filtration precision can be achieved?
A: The titanium sintered filter offers filtration precision from 0.1 to 100 microns, depending on the titanium powder grading and sintering parameters. We can customize the pore size to your specific retention requirements. Contact us with your target particle size for a recommendation.
Q4: Is the titanium sintered filter suitable for high-temperature applications?
A: Yes. The filter maintains structural integrity at temperatures up to 300°C. This makes it suitable for high-temperature gas filtration, steam sterilization, and hot liquid processes. For applications above 300°C, please consult our engineering team for special grades.
Q5: What shapes and sizes are available?
A: Standard shapes include discs, tubes, and cartridges. Custom shapes can be manufactured to your specifications. Standard tube diameters: 10mm ~ 200mm. Standard lengths: 100mm ~ 1000mm. Disc diameters: 10mm ~ 500mm. Custom end fittings (threaded, flanged, or clamp) are available. Contact us for custom requirements.
