How does the permeability of porous foam titanium vary with pore size grade, and what is the trade-off between filtration precision and flow rate?
Permeability decreases significantly as pore size and filtration precision become finer. For example, the T9 grade with maximum pore size 2.5 µm and filtration precision 0.2 µm offers only 1.5 m³/m²·h·kPa permeability, whereas the T1 grade with 160 µm pore size and 50 µm precision achieves 800 m³/m²·h·kPa. This inverse relationship means that higher filtration precision comes at the cost of reduced flow capacity, a critical trade-off for filtration and gas diffusion applications.
Can porous foam titanium be used in welded tube assemblies under high pressure, and what are the pressure limitations?
Yes, but only specific pore size grades (T3, T4, T5) are rated for welded tube configurations, with a pressure resistance of 0.3 MPa. For static tube assemblies, all grades (T1-T9) support up to 2.0 MPa. This constraint must be considered when integrating the foam into pressurized systems; welded joints are significantly weaker than static seals.
What is the maximum operating temperature for porous foam titanium, and are there any special handling requirements for the 99.99% purity material?
The maximum operating temperature is 250°C for all grades. The material is 99.99% pure titanium, which provides excellent corrosion resistance but may require careful handling to avoid surface contamination that could affect high-purity applications. Storage in a clean, dry environment is recommended to maintain the foam's structural integrity and prevent pore clogging.
This porous foam titanium sheet (99.99% purity) is available in thicknesses from 0.6 to 3.0 mm and surface areas up to 200×300 mm, with maximum pore sizes ranging from 160 to 2.5 microns depending on grade. It withstands 250°C and 2.0 MPa static pressure, but filtration precision and permeability are inversely related across the T1–T9 series.
Positive
- High purity and versatile sizing: 99.99% purity with thicknesses from 0.6 to 3.0 mm and widths/lengths up to 200×300 mm, enabling flexible integration into lab-scale filtration, electrode substrates, or gas diffusion layers.
- Robust thermal and pressure limits: Temperature resistance up to 250°C and static pressure resistance up to 2.0 MPa (all grades) allow operation in moderate-temperature and high-pressure environments without structural failure.
Trade-offs
- Pore size not pre-specified: The product includes multiple pore grades (T1–T9) with maximum pore sizes from 160 to 2.5 microns; without explicit selection, the filtration precision and permeability vary significantly, requiring the buyer to define the required grade.
- Permeability drops with finer filtration: As pore size decreases from 160 to 2.5 microns, permeability falls from 800 to 1.5 M³/M²·h·Kpa, so achieving finer filtration precision (down to 0.2 microns) drastically reduces flow rate capabilities.
