2A14 aluminum plate is a metal material used in situations that require high strength and hardness (including high temperatures). The characteristic of 2A14 series aluminum plates is their high hardness, with the highest content of copper in the original category, around 3-5%. 2A14 series aluminum plates belong to aviation aluminum materials and are not commonly used in conventional industries. There are few manufacturers in China that produce 2A14 series aluminum plates. The quality cannot be compared with foreign countries. The imported aluminum plates are mainly provided by Korean and German production enterprises. With the development of China’s aerospace industry, the production technology of 2A14 series aluminum plates will be further improved. Aircraft heavy, forged, thick plates, and extruded materials, wheels and structural components, multi-stage rocket first stage fuel tanks and spacecraft components, truck structures and suspension system components.
