Aluminum foil for capacitors

Henan signi produces Aluminum foil for capacitors, including corrosion foil and formed foil. It is the key basic material for the production of aluminum electrolytic capacitors. It is used to carry charges. Together with the electrolyte, it accounts for 30%-70% of the production cost of aluminum electrolytic capacitors. The size of the capacitor is different). Since electrode foils are basically used in the production of aluminum electrolytic capacitors, their development is highly dependent on the development of the aluminum electrolytic capacitor industry.



The performance of aluminum foil for capacitors determines the capacity, leakage current, loss, life, reliability, volume and other key technical indicators of aluminum electrolytic capacitors. It is also the part of aluminum electrolytic capacitors with the highest technical content and added value. There is no high-quality electrode. It is impossible to make high-performance aluminum electrolytic capacitors with foil. For electrode foil production, corrosion and chemical conversion technology are the core technologies of electrode foil manufacturing.
The aluminum foil for capacitors industry, as the country’s key basic material industry, is the country’s key development and priority support industry. The development level of the electrode foil industry directly determines the development level of China’s aluminum electrolytic capacitor industry, and the electrode foil manufacturing industry is determined to a certain extent And affect the development and progress of downstream and terminal industries
