2 series aluminum alloys belong to Al+Cu alloys, in which the metal content of Cu reaches 3%-5%. 2××× aluminum is relatively rare in industrial applications. Because of the high hardness of the 2 series aluminum coil material, it is mostly used in aerospace building materials, such as aircraft cabin panels.

Common alloy models in 2××× aluminum alloy coil are 2A12, 2017, 2024, 2A11, A16 (LY16) 2A06 (LY6) 2117 2A12, 2124 and so on.

2 series aluminum coils have higher requirements on the hardness of the material and better quality production countries include German aluminum alloys and Korean aluminum alloys. With the further development of China’s aerospace industry, the production technology of 2 series aluminum alloys has also made great progress and is widely exported. to all over the world.
