Copper wire mesh is widely used in EMI shielding, industrial filtration, laboratory screening, battery production, and architectural protection, thanks to its exceptional electrical conductivity and flexible processing characteristics. This guide provides a complete overview of copper mesh—including performance, specifications, common uses, and how to choose the right mesh for your project.
1. What Is Copper Wire Mesh?
Copper wire mesh is a plain-woven metal fabric made using pure copper wire (C11000).
It combines:
High conductivity
Soft malleability
Corrosion resistance
Precise filtration strength
Excellent electromagnetic shielding
Copper mesh is offered from 8 mesh (coarse) up to 200 mesh (fine filtration).
2. Key Properties of Copper Wire Mesh



2.1 High Electrical Conductivity
Copper is among the most conductive engineering metals, making the mesh ideal for:
EMI/RFI shielding
Grounding
Faraday cages
Signal-blocking screens
Mesh structure ensures uniform contact points, improving conductivity vs. solid copper sheets.
2.2 Corrosion Resistance
Its natural oxide layer protects against:
Humidity
Atmospheric corrosion
Mild acids and alkalis
Suitable for both indoor and outdoor use.
2.3 Soft and Easy to Process
Copper mesh is much easier to form compared with stainless steel:
Easy cutting
Easy bending
Easy sealing
Works well for edging, welding, pleating
Ideal for custom-shaped filters and shielding parts
2.4 Wide Filtration Range
Available from coarse to ultra-fine mesh:
8–20 mesh → shielding & anti-rodent
40–80 mesh → industrial filtration
100–200 mesh → laboratory & gas-liquid separation
3. Common Applications of Copper Wire Mesh
3.1 EMI / RF Shielding
Faraday rooms
Electronic device protection
PCB grounding
High-frequency laboratories
Copper is preferred where signal stability is critical.
3.2 Industrial Filtration
Used in:
Chemical filtration
Catalyst filtration
Battery industry
Gas–liquid separation
Precision sieving
Copper’s softness allows custom filter shapes.
3.3 Architecture & Security
Anti-rodent protective mesh
Signal-blocking windows
Ventilation screens
Insect prevention with conductivity
3.4 Laboratory Research
Vacuum chamber filters
Gas separation setups
Scientific experimental equipment
