Tinned copper braided flat wire is made from high‑purity soft copper strands, precision‑woven into a flat ribbon and uniformly coated with tin. It combines copper’s high conductivity with the tin layer’s excellent solderability and corrosion resistance. The braided structure provides outstanding flexibility and fatigue resistance. Width, thickness, cross‑section, single‑wire diameter, braid density and end termination can be customized to meet specific needs, making it ideal for applications requiring reliable electrical performance, durable connections and adaptability to various operating conditions.
Precision Braiding
Uniform force distribution for a stable, durable structure.
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 or specification.
Tin Plating
Improves joint reliability and environmental 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
≥99.9% high purity soft copper ensures low resistance and high current carrying capacity.
Braided Construction
Multi-spindle braiding machines (commonly 8/12/16/24/32/48 spindles) form a uniform, dense mesh or ribbon, distributing stress to prevent single point failure.
Tin Coating
Even tin plating enhances solderability, oxidation resistance and corrosion resistance.
Optional Finishes
Available with silver plating, insulation or jacket for higher protection or special environments.
