Electronic foil is a kind of aluminum foil made by a series of rolling, cleaning and cutting processes on high-purity aluminum ingots, and is often used in electronic components. Most electronic foils are high-purity aluminum foils, such as 1070 aluminum foil, 1100 aluminum foil, etc., which have good electrical and thermal conductivity and are commonly used materials for electrolytic capacitors.
1070 aluminum foil has high plasticity, corrosion resistance, good electrical and thermal conductivity, and is suitable for aluminum foil to make gaskets and capacitors. The performance is very stable.
As an important raw material for aluminum electrolytic capacitors, electronic aluminum foil is widely used in communications, home appliances, automobiles, electronics, aviation, new materials and other fields, and the market demand is huge. The specific production process of electronic aluminum foil includes: melting-heating-hot rolling-pre-annealing-cold rolling-intermediate annealing-cold rolling-foil rolling-slitting-performance testing-packaging.
Electronic aluminum foil can be divided into high-voltage anode foil, low-voltage anode foil, negative electrode foil, etc. High-voltage anode foil is columnar corrosion, low-voltage anode foil is sponge corrosion, and medium-voltage section anode foil is worm-eaten corrosion.
High-voltage anode foil can be divided into two categories, one is high-quality high-voltage foil; the other is ordinary high-voltage foil. High-quality high-voltage anode foil is characterized by high purity, high cubic texture and thin surface oxide film.
This type of product is of high quality but high cost, with aluminum purity > 99.99%, cubic texture 96%, and vacuum heat treatment under 10-3Pa ~ 10-5Pa. Ordinary high-voltage anode foil is an economical and practical high-voltage anode foil, with aluminum purity > 99.98%, cubic texture > 92%, and vacuum heat treatment under 10-1Pa ~ 10-2Pa.
Negative electrode foil can be divided into soft state and hard state. Japan mainly uses soft state electrochemical corrosion, while Western Europe mainly uses hard state chemical corrosion. Both have their advantages and disadvantages. The soft state uses high-purity aluminum foil (>99.85%), which is copper-free and of high quality, but also has high cost; the hard state uses low-purity copper-containing aluminum foil, which has low cost.
