Welcome!
The 4000 series aluminum plates belong to the series with high silicon content. Generally, the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials and welding materials; Low melting point, good corrosion resistance Product description: It has the characteristics of heat resistance and wear resistance.
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.
