5N high purity electrode foil

The aluminum foil material for aluminum electrolytic capacitors is a sub-sector of the special materials industry for electronic information products and belongs to the category of new electronic materials industry. The new electronic material industry is one of the strategic emerging industries that the state encourages to develop.
 


5N high purity electrode foil Production process: High-purity aluminum-electronic aluminum foil-electrode foil (corrosion foil, chemical foil) The company has the production process chain of "high-purity aluminum-electronic aluminum foil-electrode foil (corroded foil, chemical foil)". Electronic aluminum foil, also known as light foil, is an intermediate product in the processing of aluminum electrode foil, which directly affects the quality of electrode foil.
 
CHALCO is one of the earliest companies engaged in the research and development of new aluminum electronic materials in China, and has the world's largest high-purity aluminum production base. After more than 50 years of development, it has become the core backbone enterprise of China's strategic new material industry. The main products include: 5N 4N high-purity aluminum, electronic aluminum foil and electrode foil and other electronic components raw materials.
 
    There is huge space for high-purity metal import substitution. The company is the only domestic enterprise with the production capacity of 5N (99.999%) high purity electrode foil
 and above ultra-high-purity aluminum and high-purity smelting and casting in China. The sputtering target industry chain is distributed in a pyramid shape. The high-purity metal supply and the high-purity sputtering target manufacturing process have high technical thresholds and large equipment investment. They are mainly monopolized by American and Japanese companies. Norway Hydro is currently the world's 5N5 high-purity The largest company in the aluminum industry. In contrast, CHALCO entered high-purity aluminum targets relatively late, and the technology gap is gradually narrowing.
