Rolled Electrolytic Copper Foil
Product Description
Copper strip is made of electrolytic copper and it goes through the processes of ingot, hot rolling, cold rolling, heat treatment, surface cleaning, cutting, finishing, and then packing. The material has excellent thermal and electrical conduction, flexible ductility and good corrosion resistance performance. It has been widely used in electrical, automotive, communications, hardware, decoration and other industries.
Features:
1. Double -side treated copper foil with high binding force to laminate
2. Excellent etchability.
3. Direct multi-layer laminate
4. the treated foil is pink
