Product Advantages
Ultra-high flexibility: Micro-stranded construction (single wire down to 0.05mm) ensures a small bending radius and high resistance to repeated flexing, suitable for high-dynamic applications.
Excellent conductivity: Made of high-purity Cu-ETP copper (≥99.95%), low DC resistance, reduced power loss, especially effective for high‑frequency current transmission.
Multiple finishes: Available bare or tin-plated. Tin plating provides effective oxidation and corrosion resistance, and improves soldering reliability.
Standard compliance: Strictly manufactured according to GB/T12970.4-2009, ensuring consistency and traceability.
Flexible customization: Structure, cross-section, and packing can be adjusted upon request; non-standard solutions are available.
Operating Conditions
Temperature range:
–40°C to +200°C (tin-plated)
Environment:
Dry or moderate humidity. Avoid prolonged contact with acids, alkalis, or corrosive gases. Tin-plated version can be used in mildly corrosive environments.
Current rating:
Refer to the max. DC resistance values in the specification table and select the appropriate cross‑section based on actual heat dissipation of the equipment.
Maintenance and Care
Periodically inspect the conductor surface for oxidation, blackening, or mechanical damage, especially when used in high-humidity or chemical atmospheres.
During installation, avoid excessive tension or kinking; keep the minimum bending radius no less than 5 times the outer diameter of the wire.
For tin-plated products stored long‑term, use sealed packaging and store in a dry, clean environment to prevent discoloration of the tin layer.
In high-frequency equipment, ensure that terminal crimping or soldering is secure to avoid local overheating due to high contact resistance.
After-Sales Service
Factory inspection reports and material certificates are provided, traceable to raw material batches.
Technical team available to assist with selection, structural optimisation, and failure analysis.
Small batch sample orders supported; lead time for bulk orders is usually 15–25 working days (expediting possible upon request).

Frequently Asked Questions
Our copper braided wires are manufactured from high-purity annealed Cu-ETP wires (C11000) with a copper content of ≥ 99.95%, ensuring exceptional electrical conductivity and minimal power loss.
We supply wires with both bare copper and tin-plated finishes. Tin plating delivers superior oxidation and corrosion resistance, significantly extending lifespan in harsh environments and improving soldering performance.
All products are strictly manufactured according to the GB/T12970.4-2009 standard, accompanied by full factory inspection reports and traceable material batch certificates.
Tin-plated copper braided wire operates reliably within a temperature range of -40°C to +200°C, making it suitable for demanding industrial and thermal environments.
Products can be packaged in rolls, on spools, or on wooden drums. Bulk order lead times are typically 15–25 working days, with expedited production available upon request.
Yes, full customization is supported. We offer single wire diameters from 0.05mm (AWG 44) to 0.12mm with custom strands, outer diameters, and cross-sections tailored to your specific application requirements.
