5N Pure Copper (99.999% Cu) is a high‑purity conductor with total impurity content below 10 parts per million. Unlike standard copper (99.9% or 99.99%), 5N copper eliminates grain boundary contamination and reduces crystal defects, offering superior electrical conductivity (≥102% IACS) and stable signal transmission.

Q1: Can I get a sample of pure copper micro wire before bulk order?
A: Yes, free samples are available upon request. You only pay shipping.
Q2: What is the lead time for this pure copper wire?
A: Samples ready in 2–3 days. Mass production takes 7–20 working days depending on your quantity.
Q3: Is there a minimum order quantity (MOQ)?
A: MOQ is 5 kgs.
Q4: How do you prevent the wire from tangling or breaking during shipping?
A: We wind it carefully on anti-static plastic spools with plastic box protection. Each spool is inspected under magnification before packing.
Q5: Do you offer guarantee for pure copper wire?
A: Yes, we offer a 12-month warranty against manufacturing defects. We also provide a Certificate of Analysis (CoA) and Mill Test Report (MTR) for each batch.
