High Conductivity CuAg2.0 Ultra Fine Silver-bearing Copper Wire For Voice Coils
Features:
High conductivity
Excellent softening resistance
Superior flex fatigue life
Stable contact performance
Customizable Ag/Cu ratio
Ultra-fine wire capability
Description:
Silver-copper alloy is a metallic material that combines the high electrical and thermal conductivity of silver with the mechanical strength, hardness, and cost efficiency of copper. Its balanced properties provide good resistance to arc erosion and welding, stable contact resistance, and reliable performance under electrical and thermal loads. The alloy can be produced in different silver-to-copper ratios, allowing its conductivity, hardness, and wear resistance to be tailored for specific technical requirements.

FAQ
Q1: Can I get a sample of silver-bearing copper wire before bulk order?
A: Yes, free samples are available upon request. You only pay shipping.
Q2: What is the lead time for this silver-bearing 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 silver-bearing 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.
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.
