Where Is Brass Woven Wire Mesh Used?
Brass woven wire mesh is most often specified for EMI/RF shielding windows and enclosures, fine filtration and screening elements, and golden decorative panels for cabinets, room dividers and furniture.
- EMI/RF shielding
- decorative screens
- antenna covers
Metallurgical Composition & Alloy Ratio Analysis
65/35 Brass Woven Wire Mesh Purity & Heat Traceability
This brass woven wire mesh is produced from 65/35 high brass wire to ASTM B134/B134M, with the Cu 60-65% / Zn 35-40% balance below comparable to UNS C26800/C27000. Every wire batch is spectrometer-tested before weaving, and each brass woven wire mesh shipment includes an EN 10204 3.1 mill certificate tied to the wire heat number — the composition that gives EMI shielding buyers the conductivity they rely on and decorative specifiers the warm golden tone they want.
- Cu: 60-65
- Zn: 35-40
- Fe: ≤0.10
- Pb: ≤0.05
Brass Woven Wire Mesh Physical & Service Limits
- EMI Shielding & Soldering：Continuous conductive contact at every wire intersection gives this brass woven wire mesh effective EMI/RF attenuation, and the mesh accepts lead or silver solder for grounding tabs and frame joints without special brazing.
- Stronger Than Pure Copper：The zinc content raises tensile strength and abrasion resistance well above red copper mesh, so fine brass woven wire mesh holds tension and resists wear in vibrating filtration duties.
- Service Boundaries：Do not use brass woven wire mesh with ammonia, ammoniacal compounds, chlorides or seawater, which trigger dezincification and stress-corrosion cracking, with susceptibility verified per ASTM B858 ammonia vapor testing. For those environments choose our phosphor bronze (SPU-WM-031) or 316 stainless families instead.
- Tarnish & Packaging：Brass woven wire mesh naturally develops a brown patina in air. Rolls are sealed with desiccant and wrapped in VCI anti-tarnish paper so the bright golden surface arrives intact for decorative use; passivation or clear lacquer can be arranged on request.
Which ASTM E2016-22 Tolerances Apply to Brass Woven Wire Mesh?
ASTM E2016-22 defines the standard tolerances for industrial woven wire cloth, and this brass woven wire mesh family's 40-200 mesh range spans its fine tolerance bands. Confirm the applicable band in your purchase order or incoming inspection plan, and request actual measured values in the pre-shipment report.
| Nominal Mesh Range | Max Wire Dia. Tolerance | Max Aperture Size Tolerance | Warp Tilt Deviation |
|---|---|---|---|
| 1 to 50 Mesh | ± 0.013 mm (0.0005 inch) | ± 3% of nominal aperture | Tilt deviation ≤ 2° |
| 51 to 200 Mesh | ± 0.008 mm (0.0003 inch) | ± 5% of nominal aperture | Tilt deviation ≤ 1.5° |
| 201 to 400 Mesh | ± 0.004 mm (0.00015 inch) | ± 8% of nominal aperture | Tilt deviation ≤ 1° |
