1. Stable properties suitable for high capacity rechargeable battery .

2. Eco-friendly products and processes.



Compare between CA copper foil and ED copper foil


1. Process: rolled copper foil (Rolling process),ED copper foil (Electrodeposition process)

2. Strength toughness: rolled copper foil is a flaky crystalline structure, so the strength and toughness is better than electrolytic copper foil, so most of the rolling copper foil used in flexible printed circuit boards.


Package:wooden carton
