Aluminum foil for electrolytic capacitors

Aluminum foil have many special characteristic: rich polish, light weight, anti-damp, anti-pollute and is the well transmit electricity body.
The aluminum foil used in electrolytic capacitors is a kind of corrosive material working under polar conditions. It has high requirements on the structure of aluminum foil. The aluminum foil used is divided into three types: cathode foil, thickness of 0.015mm~0.06mm; high pressure foil, thickness It is 0.065mm~0.1mm, and it is required to produce aluminum foil with high purity aluminum; low pressure foil with thickness of 0.06mm~0.1mm.

There are fewer manufacturers of domestic electrolytic capacitor aluminum foil, mainly because the market demand is not large, and the production technology has a big gap with advanced countries. However, aluminum electrolytic capacitors have good performance, low price and wide application, so the market prospect is very good. At present, Japan's annual demand is 45,000 tons, which is six times that of the Chinese market. With the development of the electronics industry and China becoming a major industrial production base, the market demand for electrolytic capacitor aluminum foil is broad.
