Tinned Copper Wire Mesh

Description

Tinned Copper Wire Mesh is a metallic mesh material woven from pure copper wires coated with a tin layer. The base material is high-purity copper (typically ≥99.9%), with a uniform tin protective layer (tin content approximately 5-20%) applied to the copper wires through electroplating or hot-dip tinning processes. This tin coating significantly enhances the wire’s oxidation and corrosion resistance, particularly against moisture, salt spray, and weak acidic/alkaline environments.

Brief introductions of the tinned copper mesh size:

—Mesh size: 1-200 mesh;  Roll size: 1*30m

Features of tinned copper mesh:

1. Excellent Conductivity: Retains copper’s high conductivity (≥95% IACS), ideal for electromagnetic shielding, grounding grids, etc.
2. Enhanced Corrosion Resistance: The tin layer isolates copper from air/water, preventing oxidation and extending service life.
3. Improved Solderability: The tin-coated surface facilitates soldering, enhancing connections in electronic components.
4. Flexibility & Durability: Maintains copper’s ductility and can be woven into flexible meshes with varying densities (e.g., 60-200 mesh).

Primary Applications of tinned copper wire mesh:

• Electronics & Electrical: PCB shielding layers, grounding arrays, cable braiding.
• Marine Engineering: Anti-corrosion filters for ship equipment, components in desalination systems.
• Industrial Filtration: Screening of chemical/acidic liquids, food-grade filtration (compliant with FDA standards).
• Architectural Design: Decorative meshes with conductive and anti-oxidation properties.

Compared to standard copper mesh, its rust resistance is improved by 3-5 times, and it offers a lower cost than silver-plated alternatives, making it a cost-effective solution for corrosion-resistant conductive applications.
