High Purity OCC 5N 99.999% Cu Single Crystal Pure Copper Ultra Thin Wire For Speakers
Features:
- Extremely High Conductivity
- Ultra‑High Purity
- Excellent Thermal Conductivity
- Good Solderability & Bondability
- Optimal for Audio & Precision Electronics
Description:
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

Applications
- High‑End Audio & Video: Speaker cables, interconnects, power cords, microphone cables – 5N copper delivers finer details and lower transmission loss than standard copper.
- Semiconductor & Microelectronics: Thermosonic bonding wire (gold ball bonding to copper pads), wedge bonding interconnects, fine‑pitch packaging, and flip chip solder bumps.
- Precision Instrumentation: High‑sensitivity sensors, low‑noise measurement leads, cryogenic temperature sensors (e.g., Cernox), and precision shunts.
- Medical Devices: Guidewires, neurostimulation leads, intra‑vascular ultrasound (IVUS) signal conductors, and implantable device interconnects (with appropriate coatings).
- Aerospace & Defence: High‑reliability wiring, RF/microwave transmission lines, quantum computing signal cables, and low‑loss coaxial cables.
- Research & Laboratory: Ultra‑low temperature conductors (down to 1.5K), electromagnet coils, and high‑frequency probe station needles.
FAQ
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 products?
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.
Q6: How to deal with faulty wire (e.g., breakage or diameter out of tolerance)?
A: First, our wire is inspected and tested for continuity before packing; defect rate is below 0.5%. Second, during the warranty period, we will replace the faulty length on your next order. For large batch issues, we will re-spool a new coil at no cost or discuss a partial refund based on actual test results.
