Shanghai Metal Corporation is a leading Electronic Aluminum Foil manufacturer and supplier.
As a key raw material for the production of aluminum electrolytic capacitors, aluminum foil together with the electrolyte accounts for the raw material cost of aluminum electrolytic capacitors. The aluminum foil for capacitors relates to an electrode foil and an electronic aluminum foil, which are different in processing depth, and the electronic aluminum foil is a raw material for electrode foil production. Its complete industrial chain is: fine aluminum (high-purity aluminum ingot) - electronic aluminum foil (light foil) - electrode foil (corrosion foil, chemical foil) - aluminum electrolytic capacitor - electronic machine (such as color TV, etc.).

Electronic Aluminum Foil, also known as electronic aluminum foil, is generally produced from high-purity aluminum, which is divided into three types: medium-high voltage anode foil. Low voltage electrolytic capacitor anode foil (hard state) by DC or AC corrosion treatment, chemical treatment after being as low-voltage aluminum electrolytic capacitor foil use.

Processing method of Electronic Aluminum Foil:
1. Production stage: melting casting - soaking - hot rolling - pre-annealing - cold rolling - intermediate annealing - cold rolling - thin rolling - slitting - performance testing - packaging
2. Corrosion energization stage: firstly increase the surface area of the cathode and anode aluminum foil by etching (Etching) of the raw material aluminum foil to form a corrosion foil; then, in the aspect of the anode aluminum foil, in the form of through formation, An oxide film (AL2O3) is formed on the surface as a dielectric material to form a foil.
