Overview
200 mesh is the transition size between the coarse support layer and the fine filtration layer of a multi-layer sintered cartridge. Cut point ≈75 µm; sintered filtration efficiency typically lands in the 5–15 µm range, which is the core medium-precision band for sintered metal filter cartridges.
A single 200-mesh layer also makes a stronger membrane substrate than 250 mesh when burst-strength matters more than ultimate surface smoothness.

Identical to the 150 mesh SKU, conforming to UNS S31603. OES-measured per-batch chemistry shipped on the CoA.
Physical properties (typical)
| Property | Method | Typical value |
|---|---|---|
| Sieve cut point | Mechanical sieving | 200 mesh (≈75 µm) passing |
| D10 / D50 / D90 | Laser diffraction | 25 / 60 / 80 µm |
| Apparent density | ASTM B212 | 2.6–2.9 g/cm³ |
| Tap density | ASTM B527 | 3.4–3.8 g/cm³ |
| Oxygen content | LECO | ≤ 3000 ppm |
Recommended applications
- Medium-precision single-layer cartridges — sintered, typical filtration efficiency 5–15 µm.
- Multi-layer transition layer — sandwich between 150-mesh support and 250-mesh fine layer to avoid abrupt pore-size discontinuity.
- PTFE membrane substrate — when substrate burst strength is the priority over surface roughness, 200 mesh is the better choice over 250 mesh.
Packaging & MOQ
Same as other SKUs: vacuum-sealed pouch in steel drum, palletized; MOQ 25 kg; 1 kg samples free.
