Electronic foil, also known as electronic foil, also known as electrolytic capacitor aluminum foil, is used to make aluminum electrolytic capacitor electrode foil used in the blank. As a high-purity aluminum foil, the electronic foil is made of aluminum (high purity aluminum) aluminum ingots by hot rolling to aluminum, and then further cold-rolled, annealed. The specific production process is: casting - are hot - hot rolling - pre-annealing - cold rolling - intermediate annealing - cold rolling - foil rolling - cutting - performance testing - packaging.
In recent years due to the rapid growth of the domestic electronic information industry, as well as traditional industries such as home appliances and other stable growth, the market demand for aluminum electrolytic capacitors growing. Japan, South Korea, Taiwan and other enterprises of aluminum electrolytic capacitor production base to accelerate the transfer of China, and aluminum electrolytic capacitor production growth, prompting China's electronic foil processing industry to develop rapidly.
huawei Aluminum has introduced a world-class foil rolling mill, using Andritz plate roll, to achieve high quality aluminum foil provides a guarantee. In the production process to strictly control the processing quality of electronic aluminum foil, texture, grain structure, composition, etc., product performance reached the international advanced level. Its production of 3003 aluminum foil has excellent anti-rust performance, strength than 1100 about 10% higher, forming, soluble, corrosion resistance are good. It is an excellent material for making electronic foil.
