Pure Copper plain weave wire mesh combines the construction of plain weave wire mesh (ISO 9044 / ASTM E2016) with the properties of C11000: good atmospheric resistance with a stable patina; outstanding conductivity, non-magnetic, service to approx. +200 °C. This page summarizes the grade data, its behavior in filtration service, comparable alloys, and the specifications supplied.
Why Choose Pure Copper for Plain Weave Wire Mesh
The EMI/RFI shielding and Faraday-cage mesh material. For plain weave wire mesh, this matters when good atmospheric resistance with a stable patina; outstanding conductivity is the controlling requirement.
Alloy Properties
| Grade designation | C11000 |
|---|---|
| Magnetic response | Non-magnetic |
| Service temperature | approx. +200 °C |
| Corrosion characteristic | Good atmospheric resistance with a stable patina; outstanding conductivity |
Corrosion Behavior in Filtration Service
Copper and brass plain weave wire mesh resist atmospheric corrosion and fresh water well, tarnishing to a stable patina. Avoid ammonia and ammonium compounds (stress-corrosion cracking of brass) and strong oxidizing acids. In marine service, phosphor bronze outperforms plain brass.
Cleaning & Compatibility
Clean copper-alloy mesh with mild detergent or dilute citric acid; avoid ammonia-based cleaners entirely. In contact with more noble metals in wet service the copper alloy becomes the sacrificial partner — isolate or accept the loss rate.

Where Pure Copper Plain Weave Wire Mesh Is Used
- Process filtration: strainer baskets, filter discs and pump-intake screens cut from stainless steel wire cloth.
- Food & beverage: sifter screens, dewatering and rinse screens in 304 and 316L.
- OEM fabrication: stainless steel mesh screens pressed, rimmed or spot-welded into appliance and machine parts.
- Laboratory & QA: routine sieving and sample screening where a certified test sieve is not required.
Ordering Plain Weave Wire Mesh in Pure Copper
- Mesh count and wire diameter: Specify both — two 100-mesh cloths with different wires have different apertures and open areas.
- Aperture or micron: Quote the opening (mm or µm) you need to retain; the table converts mesh count to micron for every size.
- Alloy & supply form: 304 for general use, 316L for chlorides and food CIP; rolls of 1–1.5 m width, cut sheets, discs or slit strip.
Mistakes to Avoid with Plain Weave Wire Mesh
- Ordering by mesh count only and receiving a heavier or lighter wire than expected.
- Using plain weave below about 40 µm, where twill or dutch weave carries the fine wire far better.
