2124 Aerospace Aluminum Sheet Plate
What is 2124 aluminum?
2124 aluminum is a high-strength alloy, belonging to the 2000 series (Al-Cu), known for its excellent strength-to-weight ratio and fatigue resistance. It is particularly suitable for aerospace and military applications, where the integrity of structures under stress is critical.
2124 aluminum alloy is a high-strength, heat-treatable alloy primarily used in aerospace applications. It is a higher-purity version of 2024 aluminum alloy, specifically developed for high-temperature environments.
After heat treatment, 2124 alloy exhibits high strength and hardness, making it suitable for manufacturing aircraft structures, spacecraft components, and other applications requiring high strength and low weight.
2124 aluminum alloy is typically supplied in the T851 temper, and 2124-T851 aluminum plate has significantly higher fracture toughness than 2024-T851, making it suitable for applications that require higher short transverse ductility, high strength, and excellent machinability. This alloy also has excellent exfoliation corrosion resistance, with fatigue performance similar to 2024-T851. It is widely used in high-performance structural components in the aerospace industry.
Characteristics of 2124 Aerospace Aluminum Plate
- High Strength: Compared to other aluminum alloys, 2124 offers excellent strength, making it suitable for structures that must withstand large loads. It maintains performance even at high temperatures (up to ~150°C).
- Corrosion Resistance: The corrosion resistance of 2124 aluminum is lower than that of the 6000/7000 series. While the corrosion resistance of aluminum-copper alloys is relatively poor, proper surface treatments can enhance its corrosion resistance. Coating or anodizing is often required.
- Fatigue Resistance: 2124 aluminum alloy is highly suitable for cyclic loading, which is critical in aerospace applications.
- Machinability: After appropriate heat treatment, 2124 aluminum offers good machinability and can undergo various machining processes.
- Heat Treatment: 2124 aluminum typically requires heat treatment to achieve optimal performance, with common processes including quenching and aging.

Applications of 2124 Aircraft Aluminum Plate
Due to its high strength and resistance to stress corrosion cracking, 2124 aluminum is commonly used in aerospace structures, including aircraft wings, fuselage, and other critical components.
2124 aluminum plate is primarily used for aircraft structural components, wings, fuselage, and other load-bearing parts.
1. Aircraft Structural Components
2124 aluminum alloy is commonly used in the manufacturing of primary structural components for aircraft, such as frames, support beams, and other load-bearing structures. These parts need to withstand high loads and fatigue, making the strength and rigidity of 2124 aluminum alloy an ideal choice.
2. Wings
Wings are critical components of an aircraft, and 2124 aluminum alloy is often used in the primary load-bearing structures of wings, such as wing beams and ribs. Its high strength and fatigue resistance allow wings to effectively bear aerodynamic loads during flight.
3. Fuselage
In the design of aircraft fuselage, 2124 aluminum alloy is used to manufacture important load-bearing components, such as cross beams and longitudinal beams. These parts need to provide sufficient strength and stability to ensure the overall structural integrity of the aircraft.
4. Other Load-Bearing Components
In addition to wings and fuselage, 2124 aluminum alloy is also used in other load-bearing components, such as landing gear brackets, connectors, and other structural elements. These parts must withstand significant impacts and loads during flight and landing.
