Frequently Asked Questions

Find answers to common questions about our copper wire products, specifications, and ordering process.

What is the difference between bare copper and tinned copper wire?

Bare copper wire is pure copper with no coating, offering maximum conductivity. Tinned copper wire has a thin layer of tin plating that provides enhanced corrosion resistance, better solderability, and protection against oxidation, making it ideal for humid or marine environments.

What are the advantages of silver-plated copper wire?

Silver-plated copper wire combines the high conductivity of copper with the superior surface properties of silver. It offers excellent performance at high frequencies, better thermal stability, and resistance to oxidation, making it ideal for aerospace, defense, and RF applications.

Can I customize wire specifications?

Yes, we offer customization for wire diameter, stranding configuration, plating thickness, packaging, and length. Contact our team with your specific requirements for a tailored solution.

What certifications do your products have?

Our manufacturing processes are ISO and CE certified. We adhere to international quality standards and can provide material test reports (MTRs) and compliance documentation upon request.

How do you ensure product quality?

We implement strict quality control at every stage—from raw material inspection to final product testing. Our in-house lab conducts conductivity, tensile strength, and dimensional accuracy tests to ensure consistency and reliability.
