Gold-Plated Copper Alloy Wire - Braiding Core for EMI Shielding is engineered to provide superior electromagnetic interference (EMI) shielding performance while maintaining excellent flexibility, conductivity, and corrosion resistance. Built with a high-conductivity copper alloy core and a uniform gold-plated surface, this wire serves as an ideal material for braided shielding layers in high-frequency cables and sensitive electronic assemblies.
Its consistent diameter and bright, oxide-free surface ensure efficient braiding processes and long-lasting EMI protection in dynamic environments.
Gold-plated surface ensures low resistance and strong corrosion protection
Flexible mechanical properties support dense and durable braided structures
Stable high-frequency performance minimizes EMI and signal loss
Smooth, bright finish optimizes braiding efficiency and material handling
Customizable strand construction and plating thickness for specific shielding requirements
Braided shielding for high-speed communication and data cables
RF coaxial cable shielding and flexible antenna feeder protection
Aerospace, defense, and medical-grade EMI shielding solutions
Industrial automation and instrumentation cable braiding
Shielding layers for wearable devices, sensors, and smart electronics
Material: High-Conductivity Gold-Plated Copper Alloy
Surface Finish: Bright, Smooth, Free of Surface Contamination
Diameter Range: 0.03mm-1.0mm (configurable for different braid densities)
Compliance: RoHS / ISO9001 / REACH certified manufacturing
Packaging: Braiding rolls, precision spools, or customer-specific formats
