Frequently Asked Questions

Get answers to common questions about our copper foils and services.

What is the difference between ED Copper Foil and Rolled Copper Foil?

ED (Electrodeposited) Copper Foil is produced by electroplating and has a rougher surface for better adhesion in PCBs. Rolled Copper Foil is mechanically rolled, resulting in a smoother surface and higher ductility, ideal for flexible circuits and high-reliability applications.

What thicknesses are available for lithium-ion battery copper foil?

We offer ultra-thin copper foils from 5μm to 12μm, with standard options at 6μm, 7μm, 8μm, and 10μm. Custom thicknesses are available upon request for high-energy-density battery applications.

Do you provide samples?

Yes, we offer free samples for qualified customers. Please contact us with your requirements and shipping address to request a sample pack of our most popular copper foil grades.

What certifications do your products have?

Our copper foils are manufactured under ISO quality systems and meet RoHS, REACH, and SGS standards. Material test reports and certificates of compliance are available for every shipment.

What is the minimum order quantity (MOQ)?

MOQ varies by product type and thickness. For standard ED and Rolled Copper Foil, MOQ starts at 50kg. For battery foils, MOQ is typically 100kg. Contact us for specific product MOQs and pricing.
