Rolled Copper Foil

The rolled copper foil is a high-quality product made of pure copper material and is widely used in various industries. The copper foil features high conductivity, high strength, excellent performance and good corrosion resistance. It is widely applied in fields such as lithium batteries, rolled copper foil and ultra-thin copper foil. Our copper foil thickness ranges from 0.005 millimeters to 0.07 millimeters, and can also be customized according to customer requirements. The width can be customized from 100 millimeters to 1000 millimeters, and the length can also be customized from 100 millimeters to 1000 millimeters. Copper foil is available in both rolled and sheet forms.

Rolled copper foil is mainly applied in fields such as computers, 5G communication, automotive electronics, aerospace, new energy, etc.

Rolled copper foil is a product made by repeatedly rolling and annealing high-precision copper strips (with a thickness usually less than 150 micrometers) based on the principle of plastic processing (with a thickness usually ranging from 4 to 100 micrometers and a width usually less than 800 millimeters). Its ductility, bending resistance and conductivity are all superior to those of electrolytic copper foil, and its copper purity is also higher. Currently, electrolytic copper foil is mainly used in the production of rigid circuit boards, while rolled copper foil is mainly used in flexible and high-frequency circuit boards.
