2024 Aerospace Aluminum Extrusion

2024 aluminum extrusions are known for their high strength and good fatigue resistance, making them commonly used in aerospace applications. Their main characteristics include excellent tensile strength and relatively low corrosion resistance, which necessitates coatings or anodizing in some applications.

In terms of processing, 2024 aluminum is typically formed through hot extrusion, making it suitable for manufacturing complex-shaped profiles such as frames, brackets, and components. Additionally, its weldability is generally poor, and mechanical connections are often preferred.

2024 requires solution heat treatment to achieve optimal performance, particularly for applications needing high strength-to-weight ratios and good fatigue resistance. It can only be welded using friction welding and has average machinability. Due to its high strength and fatigue resistance, 2024 is widely used in aircraft structures, especially in tension-bearing wing and fuselage structures. 2024 is available in different temper states.
