Fabrication technology of 3003 electronic aluminum foil

Electronic aluminum foil, also known as electronic foil and electrolytic capacitor aluminum foil, is the electrode foil blank used for the production of aluminum electrolytic capacitors. As a high-purity aluminum foil, the electronic foil is made of aluminum (high purity aluminum) ingots by hot rolling to aluminum plate, and then for cold-rolled and annealed. The specific production process is: casting – hot – hot rolling – pre-annealing – cold rolling – intermediate annealing – cold rolling – foil rolling – cutting – performance testing – packaging.
