Aluminum is a versatile material that is used in a wide range of industries, from aerospace to automotive to construction. One of the most popular aluminum alloys is 2024, which is known for its high strength and excellent machinability. Within the 2024 alloy family, two of the most common tempers are T351 and T651. In this article, we will explore the differences between 2024 T351 and 2024 T651 aluminum alloy, and the applications where each is best suited.
2024 aluminum alloy is a high-strength aluminum alloy that is often used in aerospace applications. It is composed primarily of aluminum, with copper as the primary alloying element. Other elements, such as manganese, magnesium, and iron, are also present in small quantities. The addition of copper to the aluminum matrix provides the alloy with excellent strength and fatigue resistance, making it ideal for structural applications where high strength-to-weight ratio is required.
2024 T351 and 2024 T651 are two of the most common tempers for 2024 aluminum alloy. The main difference between the two tempers is the method of heat treatment used to achieve the desired properties. The "T" in the temper designation stands for "solution heat-treated," which is a process that involves heating the alloy to a specific temperature and then quenching it in water or other cooling medium to rapidly cool it down. This process helps to dissolve the alloying elements in the aluminum matrix and create a uniform microstructure.
2024 T351 is a temper designation for 2024 aluminum alloy that has been solution heat-treated and naturally aged. The "T351" temper is achieved by heating the alloy to a specific temperature and then quenching it in water to rapidly cool it down. This process helps to dissolve the alloying elements in the aluminum matrix and create a uniform microstructure. The alloy is then aged at room temperature for a period of time to allow the alloying elements to precipitate out and form fine particles that strengthen the material.
2024 T651 is a temper designation for 2024 aluminum alloy that has been solution heat-treated and artificially aged. The "T651" temper is achieved by heating the alloy to a specific temperature and then quenching it in water to rapidly cool it down. This process helps to dissolve the alloying elements in the aluminum matrix and create a uniform microstructure. The alloy is then artificially aged at an elevated temperature for a period of time to allow the alloying elements to precipitate out and form fine particles that strengthen the material.
2024 T351 and 2024 T651 aluminum alloy have similar mechanical properties, but there are some differences between the two tempers. The main difference is in the strength and ductility of the two tempers. 2024 T651 has higher strength and lower ductility than 2024 T351. This is because the artificial aging process used in the T651 temper allows for more control over the precipitation of the alloying elements, resulting in a more uniform and fine distribution of strengthening particles throughout the material.
2024 T351 aluminum alloy has a tensile strength of 470 MPa (68 ksi) and a yield strength of 325 MPa (47 ksi). It has an elongation of 20% and a Brinell hardness of 120. The fatigue strength of 2024 T351 is 160 MPa (23 ksi) at 500,000 cycles.
2024 T651 aluminum alloy has a tensile strength of 470 MPa (68 ksi) and a yield strength of 325 MPa (47 ksi). It has an elongation of 10% and a Brinell hardness of 120. The fatigue strength of 2024 T651 is 160 MPa (23 ksi) at 500,000 cycles.
2024 T351 and 2024 T651 aluminum alloy are used in a wide range of applications, from aerospace to automotive to construction. The high strength and excellent machinability of the alloy make it ideal for structural components, engine components, propeller components, high-speed trains, hub frames for automobiles, ship hull structures, ship panels, and building curtain walls.
2024 T351 aluminum alloy is commonly used in aerospace applications, such as aircraft structural components, engine components, and propeller components.
