Expanded Copper Micro Mesh

Expanded copper micro mesh is available in mesh counts ranging from 2 to 200, with wire thickness typically between 0.10mm and 0.30mm, customizable down to 0.05mm or up to 1mm. Opening sizes generally range from 4mm to 5mm, allowing manufacturers to select the exact porosity and density needed for their shielding or filtration application.

Yes, copper's high electrical conductivity makes it one of the most effective materials for EMI/RFI shielding. The knitted mesh structure provides continuous conductive pathways that attenuate electromagnetic interference while remaining flexible enough to conform to gaskets, cable shields, and enclosure seals in electronic and electrical assemblies.

Copper micro mesh offers good heat resistance for most industrial applications, maintaining structural integrity and conductivity across a wide temperature range. However, for extreme high-temperature or highly corrosive environments, customers should confirm specific operating conditions with our technical team to ensure the material selection meets performance requirements.

Copper micro mesh can be easily cut, formed, and welded to fit specific component designs, and its 300% stretching capacity allows it to be shaped into gaskets, sleeves, or custom geometries. This flexibility makes it well suited for integration into EMI shielding gaskets, grounding connectors, and filtration cartridges.

Expanded copper micro mesh is commonly supplied in 50-meter length rolls, with custom widths and lengths available upon request. This roll format allows fabricators and OEMs to cut mesh to size for production runs while minimizing material waste and simplifying inventory management.

Yes, copper micro mesh is made from up to 95% recyclable, non-toxic material, supporting eco-friendly manufacturing practices. This makes it a suitable choice for companies prioritizing sustainability in their supply chain while still requiring high-performance conductive and corrosion-resistant materials.
