Aluminum foil, the key raw material for the production of aluminum electrolytic capacitor, is high purity aluminum (purity up to 99.9%). electrode foil is a typical representative of electronic materials. Its process integrates many disciplines and technologies such as machinery, electronics, chemical engineering, metal materials, etc. it is a new type of electronic materials and basic electronic products encouraged and supported by the state. Because of the process before and after the order known as electronic aluminum foil, electrode foil.

The nano particle coating process is used to replace the traditional electrochemical etching process to break through the limit of specific capacitence improvement of traditional process products. At the same time, the specific capacitence of core performance index is increased by more than 25%, especially suitable for the winding production of downstream aluminum electrolytic capacitors. The company's products also has obvious advantages compared with the traditional technology of leading Japanese enterprises.

Forming is a process of anodizing the etched foil (electrode foil) based on the principle of anodic oxidation. According to the different requirements for the voltage withstand value of the electrode foil, different anodic oxidation voltage (VF) is used to form an oxide film (A1203) on the surface of the foil as the dielectric to make the forming foil. Formation technology determines specific capacitence, leakage current and dissipation factor - the higher the formation technology, the higher the specific capacitence, the smaller the dissipation factor and the longer the life of capacitor.

Aluminum electrolytic capacitor is a common electronic component, its core is made of anode aluminum foil, electrolytic paper, cathode aluminum foil, electrolytic paper and so on. After the core is immersed in electrolyte, it is sealed with aluminum shell and rubber cover to form electrolytic capacitor. As long as the raw material of electrode foil electrolytic capacitor, it is the part with the highest end content and added value.
