Specification data for 80 mesh plain weave wire mesh to ISO 9044 / ASTM E2016: aperture and micron rating, standard and alternative wire diameters, open area, weight per square metre, and the applications this fineness is commonly used for.
80 Mesh Specification Row (ISO 9044 / ASTM E2016)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Weight SS (kg/mu00b2) | Reference standard |
|---|---|---|---|---|---|---|
| 80-Mesh | 0.140 | 0.177 | 178 | 31.3 | 0.81 | ISO 9044 |
80 Mesh to Micron & Aperture
| Openings per inch | 80 |
|---|---|
| Aperture (opening width) | 0.18 mm |
| Micron rating | 178 µm |
| Standard wire diameter | 0.14 mm |
| Open area | 31.2 % |
Aperture = (25.4 mm ÷ mesh count) − wire diameter. The micron rating equals the aperture in micrometres; actual retention also depends on particle shape and cake formation.
Wire Diameter Options at 80 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 0.182 mm | 0.136 mm | 136 µm | 18.2 % | 1.36 kg/m² |
| Standard wire | 0.140 mm | 0.178 mm | 178 µm | 31.3 % | 0.81 kg/m² |
| Fine wire | 0.105 mm | 0.213 mm | 213 µm | 44.8 % | 0.45 kg/m² |
Heavier wire adds strength and abrasion life but closes the aperture; finer wire opens the aperture and raises throughput at the cost of durability. Specify mesh count AND wire diameter to fix the aperture unambiguously.
Open Area & Flow at 80 Mesh
The standard 80 mesh weave presents an open area of about 31.2%. At this count the mesh presents little flow resistance; selection is normally driven by particle retention and mechanical strength rather than pressure drop.
80 Mesh Cloth Weight
Standard 80 mesh stainless cloth weighs approximately 0.81 kg/m² (density 7.93 g/cm³ basis; brass and copper weave roughly 10% heavier, aluminum about one third). Use this figure for roll handling and freight estimation.
Typical Applications for 80 Mesh Plain Weave Wire Mesh
80 mesh plain weave wire mesh is commonly specified for general straining and sieving, paint and coating filtration, grease filters, insect screening, grain cleaning and pre-filtration ahead of fine media.
Plain, Twill or Dutch Weave at This Rating?
Plain square weave is the standard at this count: every opening is a true square of the stated aperture, retention is absolute for hard spherical particles, and the cloth is easy to clean.
