Manufacture Technology of Electronic Foil for 3003 Aluminum Foil


3003 Aluminum Foil


The electronic aluminum foil is also called an electrolytic capacitor aluminum foil, and is a material for producing an electrode foil for an aluminum electrolytic capacitor. As a high-purity aluminum foil, the electronic foil is formed by hot-rolling a fine aluminum (high-purity aluminum) aluminum ingot into an aluminum sheet, and further cold rolling and annealing. The specific production process is: melting casting - soaking - hot rolling - pre-annealing - cold rolling - intermediate annealing - cold rolling - foil rolling - slitting - performance testing - packaging.

In recent years, due to the rapid growth of the domestic electronic information industry and the steady growth of traditional industries such as home appliances, the demand for aluminum electrolytic capacitors is growing. The production base of aluminum electrolytic capacitors of Japanese, Korean, Taiwan and other enterprises has accelerated to China, and the output of aluminum electrolytic capacitors has grown at a high speed, prompting the rapid development of China's electronic foil processing industry.

In the production process, Shengzhou strictly controls the processing quality, texture, grain structure and composition of electronic aluminum foil, and its product performance has reached the international advanced level. The 3003 series aluminum foil produced by the company has excellent rust prevention performance, and the strength is about 10% higher than that of 1100, and the formability, the fusion property and the corrosion resistance are good. It is an excellent material for the manufacture of electronic foils.The electronic aluminum foil is also called an electrolytic capacitor aluminum foil, and is a material for producing an electrode foil for an aluminum electrolytic capacitor.
