two ××× series
two ××× Series aluminum plate: represents 2A16 (LY16), 2A06 (LY6). two ××× The series of aluminum plates are characterized by high hardness, of which the content of copper is the highest, about 3-5%. two ××× Series aluminum plate belongs to aviation aluminum, which is not often used in conventional industry. Produced in China 2 ××× There are few manufacturers of series aluminum plates. The quality cannot be compared with foreign countries. Imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of China’s aerospace industry, 2 ××× The production technology of aluminum plate series will be further improved.
