3003 Aluminum Foil For Electronic Foil

- Nov 13, 2019-

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.

The electronic aluminum foil can be classified into a high voltage anode foil, a low pressure anode foil, a negative electrode foil, and the like. The high-voltage anode foil is column-like corrosion, the low-pressure anode foil is spongy corrosion, and the anode foil of the medium-pressure section is insect-like corrosion.High-pressure anode foils can be divided into two categories, one is high-quality high-pressure foil; the other is ordinary high-pressure foil. The high-quality anode foil is characterized by “two high and one thin”, namely high-purity, high-cubic texture and thin surface oxide film. These products are of high quality but costly. Aluminum purity >99.99%, cubic texture 96%. The vacuum heat treatment is carried out under the conditions of 10-3 Pa to 10-5 Pa. Ordinary high-pressure anode foil is an economical and practical high-pressure anode foil with aluminum purity >99.98%, cubic texture >92%, vacuum heat treatment under 10-1pa~10-2pa conditions.

 

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, HTMM 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 HTMM 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.
