After the aluminum material is processed into a foil, the electronic aluminum foil is subjected to surface corrosion treatment and re-oxidation treatment, and then winding processing to make a capacitor. The aluminum foil before corrosion is called light foil, the aluminum foil after corrosion is called corroded foil, and the aluminum foil after re-oxidation treatment is called foil. Electronic aluminum foil refers to light foil, which is the key raw material for the production of aluminum electrolytic capacitors. Due to the sequence of the production process, it is divided into electronic aluminum foil and electrode foil. Electrode foil includes corrosion foil and formed foil. Electronic optical foil generally adopts 1070 aluminum foil, 3003 aluminum foil, etc., the state is h18, and the thickness is 0.02-0.05mm.

Electronic aluminum foil is high-purity aluminum foil, which is made of refined aluminum (high-purity aluminum) aluminum ingots that are hot-rolled into aluminum sheets, and then further cold-rolled and annealed. The specific production process of electronic aluminum foil includes: melting and casting-soaking-hot rolling-pre-annealing-cold rolling-intermediate annealing-cold rolling-foil rolling-slitting-performance testing-packaging.

Electronic aluminum foil requires high-purity aluminum foil, and 1070 aluminum foil is industrial pure aluminum, which has high plasticity, corrosion resistance, good electrical conductivity and thermal conductivity, and is suitable for gaskets and electrolytic capacitors made of aluminum foil. The 1070 aluminum foil produced by MC Aluminum has good shape and stable performance. It is used in electronic aluminum foil and has a high market share.

Electronic aluminum foil is widely used in communications, home appliances, automobiles, electronics and other industries. The market demand is large and the performance requirements of materials are high.
