China Flexible Copper Braided Flat Wire – High Conductivity, EMI Shielding & Customizable Manufacturers, Factories

Copper braided strip is a flexible, ribbon‑shaped conductor made of high‑purity soft copper strands (≥99.9%) woven at specified lays and strand counts. Its braided structure evenly distributes stress, preventing single‑point failure, while providing excellent conductivity, EMI shielding and grounding performance. Width, thickness, cross‑section, braid density and end termination can be customized to meet specific needs.

Product Description

Main Features
Precision Braiding Uniform force distribution, stable and durable structure without stress concentration.
Various Spindle Options Different spindle counts meet needs from fine to heavy-duty applications.
High Customizability Width, thickness, cross-section, single-wire diameter (0.05–0.15 mm), braid density and length customized per drawing.
Surface Treatment Available with or without tin/silver plating as required for corrosion resistance.
Application Fields

Widely used for power grounding and connections, rail transit, industrial machinery, EMI shielding in communication and high-frequency equipment, EV battery module links, anti-interference solutions in high-end electronics, aerospace and military grounding systems.

Structure
Copper Strand Core: High-purity soft copper ensures low impedance and high current-carrying capacity.
Braided Construction: Multi-spindle braiding machines (commonly 8/12/16/24/32/48 spindles) create a uniform, dense mesh or ribbon form.
Optional Surface Finishes: Tin or silver plating for improved solderability and corrosion resistance, or insulated/jacketed versions for extra protection.
