2024 T351 Aluminum Round Bar
2024 T351 Aluminum round bar is a high-strength aluminum alloy widely used in aerospace and other fields that require high strength and lightweight materials. Its main features include excellent strength-to-weight ratio, good fatigue resistance, and decent machinability. Due to its high copper content, 2024 alloy is one of the strongest aluminum alloys, but it also has a higher susceptibility to corrosion, especially in humid or high-temperature environments. Therefore, while it is suitable for the manufacturing of many high-performance components, it requires protection and corrosion treatment under specific conditions.
Material Meets These Standard(s): ASTM-B211, AMS-4120, AMS-QQ-A-225/6
2024 T351 Aluminum
T351 indicates that the 2024 aluminum alloy has undergone the following treatments:
- Solution Heat Treatment: The aluminum alloy is heated to a high temperature and then rapidly cooled to ensure uniform distribution of the dissolved elements, forming a stable solid solution structure. This step helps improve the hardness and strength of the aluminum alloy.
- Stretching: After the solution heat treatment, the aluminum alloy is stretched to relieve internal stresses, which helps prevent deformation or cracking during subsequent processing.
- Artificial Aging: By controlling the temperature and time, alloying elements in the aluminum alloy undergo precipitation reactions, further enhancing the material's strength. This step ensures that the aluminum alloy maintains high mechanical performance in high-temperature environments.
The T351 state of 2024 aluminum alloy offers excellent strength and hardness, making it ideal for manufacturing high-load, high-stress aerospace components.
2024 T351 Aluminum Round Bar Properties
High Strength and Fatigue Resistance
2024 T351 aluminum round bar has very high tensile strength and yield strength, making it commonly used in aerospace structural components, such as wings, fuselages, and other parts subjected to significant mechanical stress.
Its fatigue resistance is also excellent, making it suitable for use in environments with high-frequency vibration and repetitive stress, such as in aircraft structural components.
Strength-to-Weight Ratio
2024 alloy has a high strength-to-weight ratio, making it very suitable for aerospace applications that require both high strength and lightweight design. Aircraft structures need to optimize weight to improve fuel efficiency and payload capacity, and 2024 T351 aluminum alloy offers an ideal material solution.
Corrosion Resistance
Although 2024 aluminum alloy has outstanding strength, it is relatively poor in corrosion resistance due to its high copper content, particularly in humid environments or marine climates. This is a significant disadvantage of 2024 T351 aluminum round bar, which typically requires additional surface treatments (such as coatings or anodizing) to improve its corrosion resistance.
Machinability
2024 T351 aluminum round bar has good machinability and can be processed using common cutting, drilling, and grinding methods. This allows it to be precisely formed during manufacturing to meet the dimensional and tolerance requirements of various components.
2024 T351 Aluminum Round Bar Applications
Due to its unique properties, 2024 T351 aluminum alloy is widely used in various industrial and aerospace fields where high strength and low weight are required.
Aerospace
Used for manufacturing aircraft structural components such as wing frames, skins, and fuselages. These components need to have high strength to withstand the significant mechanical stresses during flight while also being lightweight to improve fuel efficiency and payload capacity.
Hydraulic Systems
2024 aluminum alloy is used to manufacture high-pressure pipes, valve components, and other critical parts in hydraulic systems due to its high strength and good fatigue resistance.
High-Stress Mechanical Components
Includes bolts, nuts, gears, pistons, and other mechanical components that need to withstand high pressure and repeated loads. 2024 T351 aluminum round bar can endure prolonged fatigue loads and maintain stable performance in high-stress environments.
Automotive and High-Performance Sports Equipment
2024 T351 aluminum alloy is also used in high-performance sports cars, such as racing vehicles, particularly in components where weight reduction is needed while maintaining high strength.
2024 T351 Aluminum Round Bar Machining Properties
Machining Methods: 2024 T351 aluminum alloy has good machinability and can be processed by conventional methods such as cutting, milling, drilling, and turning. It causes minimal tool wear, but care must be taken to avoid deformation from excessive heat treatment during processing.
Welding: Due to its high copper content, 2024 alloy has poor weldability. Cracks and other defects are likely to occur during welding, so special attention and techniques, such as preheating before welding and selecting suitable welding materials, are typically required.
2024 T351 aluminum round bar is a high-strength aluminum alloy suitable for applications requiring high mechanical strength and low weight, such as aerospace, hydraulic systems, and mechanical components. It has high fatigue resistance and good machinability, but due to its lower corrosion resistance, proper corrosion protection is necessary during use.
