The Market Prospect of Electronic Foil

Publish: Modify: Jan 05, 2023Author: From:  Haomei

The growth rate of the aluminum electrolytic capacitor industry determines the demand space of the electronic aluminum foil industry chain. The electronic foil also has many types. Learn more.

The entire industrial chain of electronic foil covers upstream resources and smelting (production of high-purity aluminum); midstream electrode foil manufacturing (electronic aluminum foil manufacturing, corrosion, chemical formation); downstream electronic component manufacturing and consumption (aluminum electrolytic capacitors, electronic complete machines).

About 70% of high-purity aluminum enters the electronic aluminum foil industry chain, and electrode foil accounts for 30-60% of the cost of aluminum electrolytic capacitors. The growth rate of the aluminum electrolytic capacitor industry determines the demand space of the electronic aluminum foil industry chain.

Electronic aluminum foil connects the two industries of aluminum processing and capacitor manufacturing. Its production needs to go through two stages of aluminum foil rolling and corrosion formation. The main process is relatively independent. The back-end corrosion and formation process will affect the quality of the final aluminum foil and the performance of the terminal capacitor.

Electronic aluminum foil(plain aluminum foil like 1050 aluminum foil roll) is obtained from high-purity aluminum ingots through special refining, calendering, cleaning and cutting processes, and then processed by erosion process to obtain corroded foil, and corroded foil is anodized to obtain formed foil.

The corrosion process pits the plain aluminum foil, increasing its surface area and thus giving aluminum electrolytic capacitors high capacitance. Electrode foil is one of the most technical parts in the industrial chain of aluminum electrolytic capacitors.

Electrode foil is a special material for aluminum electrolytic capacitors. About 95% of electrode foils are used in the production of aluminum electrolytic capacitors, and its industrial development is highly dependent on aluminum electrolytic capacitors.

The performance of the electrode foil determines many key technical indicators such as the capacity, leakage current, loss, life, and reliability of the aluminum electrolytic capacitor to a certain extent.
