Rolled copper foil


Rolled copper foil is a high-precision, ultra-thin, high-density deep-processed copper product. It has the unique advantages of high strength, high conductivity, high flexibility, and low roughness, and is widely used in electronics, 5G, integrated circuits, aerospace and other fields.

Electrolytic copper foil


Electrolytic copper foil is a metal copper foil produced using copper materials as the main raw material and an electrolytic method. After dissolving the copper material to produce a copper sulfate electrolytic solution, the copper sulfate electrolyte is electro-deposited using direct current in a special electrolytic device to produce a foil. Then, a series of treatments such as surface roughening and anti-oxidation treatment are carried out. Finally, after slitting and inspection, the finished product is produced. From a classification perspective, according to different application fields, electrolytic copper foil can be divided into lithium battery copper foil and standard copper foil; according to different copper foil thicknesses, it can be divided into ultra-thin copper foil, super-thin copper foil, thin copper foil, conventional copper foil, and thick copper foil; according to different surface conditions, it can be divided into double-sided bright copper foil, double-sided rough copper foil, double-sided coarse copper foil, single-sided rough copper foil, and ultra-low profile copper foil (VLP copper foil).
