In an increasingly electronic world, effectively mitigating Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) is a critical design challenge. Copper wire mesh stands as one of the most effective and versatile materials for creating shielding solutions, gaskets, and windows. However, not all copper mesh is created equal. For optimal performance in blocking or containing electromagnetic signals, high-conductivity copper mesh is essential.
This guide explores the key considerations for sourcing this specialized material and highlights Chinese manufacturers that have the technical expertise to produce it.
The effectiveness of a mesh shield is fundamentally governed by its Shielding Effectiveness (SE), which is directly proportional to the electrical conductivity of the material. Simply put, higher conductivity allows for better reflection and absorption of electromagnetic waves.
Material Purity: Standard brass mesh (a copper-zinc alloy) has significantly lower conductivity than pure copper. For high-performance applications, meshes woven from 99.99% pure electrolytic copper or specific high-purity alloys like Cadmium Copper (C16200) are required.
Weave Integrity: The weave must be uniform and the welds (if applicable) must be secure to prevent leakage points. Any break in the conductive path compromises the entire shield.
When searching for a supplier, look for these specific capabilities and certifications:
Material Expertise: They should openly discuss alloy types, specifically offering C11000 (ETP Copper) for excellent general conductivity or C16200 (Cadmium Copper) for higher strength and good conductivity.
Precision Weaving: Ability to produce consistent mesh counts (e.g., from 20 to 200 mesh) with precise wire diameters, ensuring the right balance between shielding effectiveness and ventilation or visibility.
Testing and Validation: The best manufacturers understand shielding requirements and can provide or reference test data for Shielding Effectiveness based on standards like ASTM D4935 or MIL-DTL-83528.
Relevant Certifications: While not always a direct indicator of product performance, an ISO 9001:2015 certified quality management system ensures process consistency and traceability.
The following manufacturers have established a strong reputation for producing wire mesh suitable for demanding electronic applications.
Anping Milesen has positioned itself as a technical expert in the wire mesh industry, with a specific focus on high-performance applications like EMI/RFI shielding. They understand that their product is a critical component in a larger system, not just a commodity.
