2000 series aluminum plate

2000 series aluminum plate represents 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, of which copper original content is the highest, about 3-5%. 2A12 aluminum alloy is a high-strength duralumin, which can be strengthened by heat treatment; 2A12 aluminum alloy spot welding has good weldability, and there is a tendency to form intergranular cracks when gas welding and argon arc welding; 2A12 aluminum alloy can be machinable after cold work hardening.

The corrosion resistance is not high, and anodizing treatment and painting method are often used or aluminum layer is added to the surface to improve corrosion resistance. 2000 series aluminum plate belongs to aviation aluminum, which is not often used in conventional industry. At present, there are fewer manufacturers producing 2000 series aluminum plates in China. However, with the development of China's aerospace industry, the aluminum plate production technology of the 2000 series will be further improved.
