2A12 Aircraft Aluminum Sheet Plate
What Is 2A12 Aluminum
2A12 aluminum alloy is an aluminum alloy with copper as the main alloying element, belonging to the aluminum-copper alloy series. It is widely used in the aerospace field, particularly in structural components that require high strength and good corrosion resistance.
2A12 aerospace-grade aluminum plates are widely applied in the aerospace industry due to their excellent mechanical properties and versatility, making them an ideal material for manufacturing high-strength structural components.
2A12 aluminum alloy belongs to the 2000 series, with copper as the main alloying element. It has high strength and good machinability. This alloy is widely used in the manufacture of various high-load components and structural parts, such as aircraft fuselage parts, skin, frames, ribs, wing beams, and rivets. However, it is not suitable for stamping and forging applications.
Despite its high strength, 2A12 aluminum alloy has poor corrosion resistance and usually requires surface treatment such as anodizing or coating to improve its corrosion resistance.
Characteristics of 2A12 Aircraft Aluminum Plate
| Feature | Description |
| High Strength and Heat Resistance | 2A12 aluminum alloy has high strength after heat treatment, making it suitable for parts that bear high loads, such as aircraft fuselage parts, skin, ribs, wing beams, and frames. Its strength remains good even at temperatures above 125°C. |
| Excellent Machinability | It has good machinability and spot-welding performance, but may develop intergranular cracks during gas welding and TIG welding. |
| Heat Treatment Strengthening | Heat treatment can significantly improve the strength of 2A12 aluminum alloy, making it suitable for processing in the hot, annealed, and quenched states. |
| Poor Corrosion Resistance | 2A12 aluminum alloy has poor corrosion resistance and requires surface treatments such as anodizing, painting, or aluminum coating to enhance its resistance to corrosion. |
| Good Weldability | It can be welded under certain conditions and is suitable for various manufacturing processes. |
