Brass Woven Mesh: an insider’s guide for buyers hunting quality copper-alloy mesh
If you’re scanning the market for copper mesh for sale, here’s the twist: most spec sheets you’ll actually want are for brass woven mesh—because brass (a copper–zinc alloy) balances conductivity, strength, and corrosion resistance better than pure copper in many use-cases. The Brass Woven Mesh from Anping’s High-tech Industrial Park (Hebei, China) is a solid example; I’ve toured facilities there, and the weaving quality is, frankly, tidy.
What’s trending (and why it matters)
Demand is rising in EMI/RFI shielding for lab benches and device housings, also in architectural screens, filtration of non-ferrous slurries, and—surprisingly—acoustic experiments where brass’s mass helps. 5G densification and EV battery lines are pushing tighter tolerance grades. Many customers say they prefer a “no-drama” weave, plain weave, consistent aperture, quick QC report. Same here.
Product snapshot: Brass Woven Mesh (copper–zinc alloy)
Materials offered: 65 brass (≈Cu65/Zn35, UNS C26800), 70 brass (≈Cu70/Zn30, C26000), 80 brass (≈Cu80/Zn20, C24000). Warp/weft diameters usually equal—clean, predictable behavior in fixtures.
| Parameter | Typical Range / Note |
|---|---|
| Mesh count | 4–200 mesh (custom up to 300 mesh) |
| Wire diameter | 0.03–1.0 mm (≈0.0012–0.039 in) |
| Open area | 5–70% (real-world use may vary) |
| Weave | Plain (standard), Twill (fine, high-count) |
| Widths / rolls | 0.5–1.5 m width; 30 m roll typical |
| Tolerances | ASTM E2016, up to Grade 2 |
| Conductivity | ≈22–28% IACS (alloy dependent) |
Process flow and QC
- Materials: Brass wire drawn from Cu–Zn rods (C26800/C26000/C24000), batch-traceable.
- Methods: Precision drawing, intermediate anneal, shuttle or rapier looms, plain/twill weave.
- Post: Straightening, degrease, optional anti-tarnish coating; flatness control.
- Testing: Mesh count/aperture to ASTM E2016 and ISO 9044; tensile to ASTM E8/E8M; salt spray to ASTM B117 (when coated); conductivity check (eddy-current method); RoHS/REACH screening.
- Service life: indoor 10–20 yrs; industrial 5–12 yrs; coastal uncoated 3–7 yrs, coated longer.
- Industries: Filtration, electronics shielding, lab test rigs, crafts/architectural, pest screening, restoration.
Customization options
Cut-to-size sheets, framed panels, tighter tolerance grades, degreased “clean-room ready,” optional lacquer, tinning, or blackened finish for low-reflectance. Lead times are reasonable, to be honest—faster than most imports I’ve seen lately.
| Vendor | Certs | Tolerance | Lead time | Customization | Price |
|---|---|---|---|---|---|
| JinJiu Wire Mesh (Anping) | ISO 9001, RoHS/REACH | ASTM E2016 Grade 2 | 7–20 days | Yes (cut, frame, coat) | $$ (value) |
| Generic Importer | Basic | Variable | 3–6 weeks | Limited | $ |
| Local Fabricator | ISO varies | Good | 2–4 weeks | Strong | $$$ |
Two quick case notes
- EMI tent liner: 70-brass, 80 mesh, plain weave, degreased; shielding effectiveness improved ≈8–12 dB in the 100 MHz–1 GHz band (lab report on file).
- Salt-air facade screen: 65-brass, 10 mesh with clear lacquer; after 500 h ASTM B117, color shift but no pitting; architect actually liked the patina.
If you need datasheets, mesh count certificates, or cut-to-size quotes for copper mesh for sale in brass alloys, ask for ASTM E2016 inspection data and RoHS/REACH compliance—saves back-and-forth later.
