Tinned Copper Wire Mesh
Yeshwant Wires is a leading and ISO-certified Tinned Copper Wire Mesh manufacturer in India, producing premium-quality meshes used in various electrical, industrial, and electronic applications. Our wire meshes are made from high-conductivity tinned copper wires that combine excellent electrical properties with corrosion resistance and mechanical durability, manufactured from 99.99% electrolytic grade copper with tin coating.
Available in plain, twilled, or knitted weave with custom mesh sizes and wire diameters, these meshes deliver exceptional corrosion resistance, electrical conductivity, flexibility, and solderability. They comply with ASTM B33, IS 191, and IEC 60028 standards and are ideal for electrical shielding, grounding systems, EMI/RFI suppression, transformers, and aerospace applications.
Description
Tinned Copper Wire Mesh is a specialized woven or knitted mesh made from copper wires with a protective tin coating. The tinned coating prevents oxidation and provides superior corrosion resistance, ensuring long service life in demanding environments. The uniform mesh spacing, smooth surface finish, and consistent quality make these meshes ideal for both mechanical and electrical integration.
These meshes are extensively used in telecommunications, aerospace, electrical, defense sectors, electromagnetic shielding, grounding mats, static protection screens, flexible connectors, marine environments, and industrial filters where reliable electrical conductivity, corrosion resistance, and flexibility are paramount for operational excellence and long-term performance.
Key Features & Advantages
- Excellent Corrosion Resistance: Tinned coating prevents oxidation, ensuring long service life.
- High Electrical Conductivity: Maintains efficient current flow for shielding and grounding applications.
- Superior Flexibility: Can be easily shaped, cut, and installed for various configurations.
- Uniform Mesh Weaving: Ensures reliable electrical contact and stable mechanical structure.
- Enhanced Solderability: Tin coating provides excellent soldering properties for electrical connections.
- Custom Sizes Available: Mesh size, strand diameter, and width can be customized as per client requirements.
Technical Specifications
| Property | Specification | Significance |
|---|---|---|
| Base Material | High-Purity Electrolytic Copper (Cu-ETP), coated with a layer of Tin (Sn-plated). | Copper provides excellent conductivity. The Tin plating drastically improves corrosion resistance (up to 10 times longer life) against humidity and oxidation, and preserves the silvery-white color, preventing verdigris (green patina). |
| Construction Type | Typically Knitted Mesh (stocking-like continuous interlocking loops) or traditional Woven Mesh (plain/twill). | The Knitted structure is highly flexible, conforms easily to irregular shapes (like cable bundles), and can be compressed for use in gaskets or filters. Woven mesh offers higher mechanical rigidity. |
| Wire Diameter | Ultra-fine single strands, commonly ranging from 0.08 mm to 0.25 mm. | The fine diameter ensures high material density (better shielding) and maintains the mesh's inherent flexibility and malleability for easy installation in tight spaces. |
| Mesh Count/Aperture | Varies widely based on application: E.g., 1 to 400 mesh (woven) or a specific Opening Size (e.g., 2 mm to 6 mm for knitted). | In Woven mesh, mesh count determines filtration capability. In Knitted mesh, the aperture size influences density and flexibility, which in turn impacts shielding effectiveness. |
| Key Function | Electromagnetic Interference (EMI) Shielding, Grounding, and RFI Gaskets. | Used extensively to wrap cable harnesses for 360° EMI/RFI suppression, line the walls of Faraday cages, and create conductive gaskets to seal equipment enclosure gaps. |
| Shielding Method | Reflection (of high-frequency E-fields) and Absorption (of low-frequency H-fields). | The mesh provides a continuous, low-impedance path to ground, shunting noise away from critical components. The interlocking or woven structure closes the apertures to shield against electromagnetic waves. |
| Operating Temperature | Wide range, typically -40°C to +125°C (limited primarily by tin's properties). | The metallic nature of the component allows it to withstand high temperatures found in industrial, automotive, or aerospace electronic compartments. |
| Additional Uses | Pest/Rodent Exclusion, Liquid/Gas Filtration, and Industrial Scrubbers/Cleaning Balls. | The material's corrosion resistance, non-flammability, and tough structure make it versatile for non-electrical industrial applications where its formability is an asset. |
Applications
