The 150 mesh specification of copper wire mesh is defined by ASTM E2016 / ISO 9044. The tables below reproduce the standard row — wire diameter, aperture and open area — and convert the count to a micron rating for filtration selection. The technical drawing redraws to the values selected.
150 Mesh Specification Row (ASTM E2016 / ISO 9044)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Alloy |
|---|---|---|---|---|---|
| 150-Mesh | 0.066 | 0.103 | 103 | 37.2 | C11000 ETP copper |
150 Mesh to Micron & Aperture
| Openings per inch | 150 |
|---|---|
| Aperture (opening width) | 0.103 mm |
| Micron rating | 103 µm |
| Standard wire diameter | 0.066 mm |
| Open area | 37.1 % |
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 150 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 0.086 mm | 0.084 mm | 84 µm | 24.3 % | 0.57 kg/m² |
| Standard wire | 0.066 mm | 0.103 mm | 103 µm | 37.2 % | 0.34 kg/m² |
| Fine wire | 0.050 mm | 0.120 mm | 120 µm | 50.1 % | 0.19 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 150 Mesh
The standard 150 mesh weave presents an open area of about 37.1%. A common design rule is to keep the clean-mesh approach velocity low enough that initial pressure drop is negligible; the mesh then acts as the cake support.
150 Mesh Cloth Weight
Standard 150 mesh stainless cloth weighs approximately 0.34 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 150 Mesh Copper Wire Mesh
150 mesh copper wire mesh is commonly specified for liquid filtration and clarification, extruder screen packs, hydraulic and fuel strainers, pharmaceutical and food sieving, and laboratory test work.
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.
When to Step Up or Down from 150 Mesh
Move to 200 mesh when particles are passing that must be retained; drop back to 120 mesh when the element blinds too quickly or the pressure drop is excessive. In a multi-layer pack, pair this count with a coarser support mesh downstream to carry the pressure load.
What Copper Wire Mesh Does
Conducting, shielding and screening with woven pure copper cloth — the go-to metal mesh for RF shielding, grounding grids, battery and electrochemical work and copper-specific screening.
Fitting & Care
- Handle with gloves; skin oils start tarnish spots that raise contact resistance on shielding seams.
- Bond seams by soldering or with conductive gasket — a mechanical overlap alone leaks RF.
