High-Purity Copper & Phosphor Bronze Mesh - Precision Filter Screen with Anti-Static, RF Shielding, Conductive Heat Dissipation

Dutai Wire Mesh

Product Overview
Our electrostatically shielded copper meshes are engineered for critical industrial applications requiring precision filtration, electromagnetic interference (EMI) suppression, and thermal management. Crafted from oxygen-free C10100 pure copper (99.99% Cu) and C51900 phosphor bronze alloys, these meshes deliver unmatched electrical conductivity (≥98% IACS), corrosion resistance, and mechanical durability. Ideal for aerospace, electronics manufacturing, laboratory equipment, and telecommunications infrastructure.

Core Functional Advantages
1. Electrostatic Dissipation (ESD Protection)

  • Surface resistance <10<sup>3</sup> Ω ensures static charge neutralization in explosive environments (ATEX/IECEx compliance)

  • Prevents component damage during semiconductor handling or pharmaceutical powder processing

2. EMI/RFI Shielding Performance

  • Faraday cage structure blocks 99.999% RF signals (tested per MIL-STD-285)

  • Critical for:
    ▸ Military communication enclosures
    ▸ Medical MRI room containment
    ▸ 5G base station EM isolation

3. Precision Filtration Capabilities

  • Tolerance: ±3μm for micron-grade separation

  • Chemical resistance: Withstands acids, alkalis, and organic solvents (pH 3-11)

  • Applications:
    ▸ Fuel cell catalyst recovery
    ▸ High-purity chemical sieving
    ▸ Food-grade oil filtration (FDA/EC1935 compliant)

4. Thermal Management Properties

  • Heat transfer coefficient: 320-380 W/m²·K

  • Used in:
    ▸ Power electronics heatsink interfaces
    ▸ Satellite thermal control systems
    ▸ Battery module cooling arrays
