Aluminum round bar 2024 is a high-strength, heat-treatable aluminum alloy bar that belongs to the 2xxx series of aluminum alloys. It is primarily composed of aluminum (Al), with copper (Cu) as the main alloying element, along with small amounts of other elements such as manganese (Mn) and small traces of other elements.

Here are some key properties of aluminum round bar 2024:

1. High strength: Aluminum 2024 round bar has excellent strength, with a tensile strength of around 470 MPa (68 ksi) and a yield strength of approximately 270 MPa (39 ksi) in the T3 temper, which is the most commonly used temper for this alloy. It is one of the strongest aluminum alloys available, making it suitable for applications that require high strength-to-weight ratio.
2. Heat treatability: Aluminum 2024 round bar is heat-treatable, allowing for improved mechanical properties and increased strength through a process called precipitation hardening. This makes it suitable for applications that require higher strength levels.
3. Good machinability: Aluminum 2024 round bar has good machinability, making it suitable for a wide range of machining operations, such as turning, milling, drilling, and tapping. It can be easily machined into various shapes and sizes.
4. Poor corrosion resistance: Aluminum 2024 round bar has poor corrosion resistance compared to other aluminum alloys, particularly in marine and acidic environments. Therefore, it is not recommended for applications where corrosion resistance is a critical requirement without appropriate protective coatings or treatments.
5. High fatigue strength: Aluminum 2024 round bar has excellent fatigue strength, making it suitable for applications that require repetitive loading and unloading, such as aerospace and automotive components.
6. Limited formability: Aluminum 2024 round bar has limited formability due to its high strength and low ductility. It may require special forming techniques and equipment for complex shapes.
7. Aerospace applications: Aluminum round bar 2024 is commonly used in aerospace applications, such as aircraft structures, aerospace components, and high-performance racing car parts, due to its high strength-to-weight ratio, fatigue resistance, and good machinability.
8. Other applications: Aluminum round bar 2024 is also used in other applications that require high strength, good machinability, and heat treatability, such as precision machinery components, military equipment, and sports equipment.

It’s important to note that specific properties and characteristics of aluminum round bar 2024 may vary depending on the temper, diameter, and other factors. Therefore, it’s always recommended to consult the relevant specifications and standards for your specific application requirements, and work with a reputable supplier to ensure that the aluminum round bar meets your intended application needs. Additionally, proper handling, storage, and processing of aluminum round bar 2024 is important to maintain its properties and performance.
