The 2000 series aluminum plates are characterized by high hardness, among which the copper element content is the highest, about 3-5%. 2000 series aluminum plate belongs to aviation aluminum, which is not often used in conventional industry. There are few manufacturers producing 2000 series aluminum plates in China. The quality cannot be compared with that of foreign countries. Imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of China's aerospace industry, the production technology of 2000 series aluminum plates will be further improved.

Aluminum coils are widely used in electronics, packaging, construction, machinery, etc. There are many aluminum coil manufacturers in China, and the production process has caught up with that of developed countries. According to the different metal elements contained in aluminum coils, aluminum coils can be roughly divided into nine categories.
