What is the yield strength of aluminum rectangular tubes?
As a supplier of aluminum rectangular tubes, I often encounter inquiries from customers about the yield strength of these products. Yield strength is a crucial mechanical property that determines the performance and suitability of aluminum rectangular tubes for various applications. In this blog post, I will delve into the concept of yield strength, its significance in the context of aluminum rectangular tubes, and how it varies based on different factors.
Understanding Yield Strength
Yield strength is defined as the stress at which a material begins to deform plastically. In simpler terms, it is the point at which a material stops behaving elastically and starts to undergo permanent deformation. When a load is applied to an aluminum rectangular tube, it initially deforms elastically, meaning it returns to its original shape once the load is removed. However, if the load exceeds the yield strength, the tube will experience plastic deformation, resulting in a permanent change in its shape.
The yield strength of a material is typically measured in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa). It is an important parameter because it determines the maximum load that a structure or component can withstand without experiencing permanent deformation. In the case of aluminum rectangular tubes, the yield strength is a critical factor in ensuring the structural integrity and safety of the applications in which they are used.
Factors Affecting the Yield Strength of Aluminum Rectangular Tubes
The yield strength of aluminum rectangular tubes can vary depending on several factors, including the alloy composition, temper, and manufacturing process. Let's take a closer look at each of these factors:
Alloy Composition
Aluminum is a versatile metal that can be alloyed with various elements to enhance its mechanical properties. Different alloy compositions have different yield strengths, depending on the specific elements added and their proportions. For example, the 6063 alloy is a popular choice for aluminum rectangular tubes due to its excellent corrosion resistance, good formability, and moderate strength. The yield strength of 6063 aluminum rectangular tubes can range from approximately 18,000 psi (124 MPa) to 28,000 psi (193 MPa), depending on the temper.
On the other hand, the 6061 alloy is known for its higher strength and better weldability compared to 6063. The yield strength of 6061 aluminum rectangular tubes can range from approximately 25,000 psi (172 MPa) to 40,000 psi (276 MPa), depending on the temper. As a supplier, I offer a wide range of aluminum rectangular tubes made from different alloys to meet the diverse needs of my customers.

Temper
The temper of an aluminum alloy refers to its heat treatment and mechanical processing history. Different tempers can significantly affect the yield strength of aluminum rectangular tubes. For example, the T52 temper is a common temper for 6063 aluminum rectangular tubes. It involves a process of stretching and stress relieving, which results in a higher yield strength compared to the as-extruded condition. The yield strength of 6063 T52 Aluminum Rectangular Tube can be around 25,000 psi (172 MPa).
Similarly, the T6 temper is a heat treatment process that involves solution heat treatment followed by artificial aging. This temper can significantly increase the yield strength of aluminum alloys. The yield strength of 6061 T6 aluminum rectangular tubes can be as high as 40,000 psi (276 MPa). As a supplier, I can provide aluminum rectangular tubes in different tempers to meet the specific strength requirements of my customers.
Manufacturing Process
The manufacturing process used to produce aluminum rectangular tubes can also have an impact on their yield strength. Extrusion is a common manufacturing process for aluminum rectangular tubes, where a heated billet of aluminum is forced through a die to form the desired shape. The extrusion process can affect the grain structure and mechanical properties of the tube. For example, a well-controlled extrusion process can result in a more uniform grain structure, which can enhance the yield strength of the tube.
In addition, other manufacturing processes such as cold working and heat treatment can also be used to further improve the yield strength of aluminum rectangular tubes. Cold working involves deforming the tube at room temperature, which can increase its strength by introducing dislocations in the crystal structure. Heat treatment processes such as annealing and aging can also be used to optimize the mechanical properties of the tube.
Importance of Yield Strength in Applications
The yield strength of aluminum rectangular tubes is of utmost importance in various applications. Here are some examples:
Structural Applications
In structural applications, such as building frames, bridges, and industrial structures, the yield strength of aluminum rectangular tubes is critical for ensuring the safety and stability of the structure. The tubes need to be able to withstand the loads and stresses imposed on them without experiencing permanent deformation. By selecting aluminum rectangular tubes with the appropriate yield strength, engineers can design structures that are both strong and lightweight.
Automotive Applications
In the automotive industry, aluminum rectangular tubes are used in various components, such as chassis frames, suspension systems, and engine mounts. The yield strength of these tubes is important for ensuring the performance and safety of the vehicle. Tubes with higher yield strength can provide better resistance to deformation and improve the overall durability of the vehicle.
Aerospace Applications
In the aerospace industry, where weight reduction is a top priority, aluminum rectangular tubes are widely used due to their high strength-to-weight ratio. The yield strength of these tubes is crucial for ensuring the structural integrity of the aircraft. Tubes with high yield strength can withstand the extreme loads and stresses encountered during flight, while also reducing the weight of the aircraft.
How to Determine the Yield Strength of Aluminum Rectangular Tubes
As a supplier, I understand the importance of providing accurate information about the yield strength of my products. When customers inquire about the yield strength of aluminum rectangular tubes, I typically provide them with the following information:

I provide the material specification of the aluminum rectangular tubes, including the alloy composition and temper. This information allows customers to determine the approximate yield strength range based on industry standards and reference materials.
Testing Results
In some cases, I can also provide testing results for the aluminum rectangular tubes. These results are obtained through mechanical testing, such as tensile testing, which measures the yield strength and other mechanical properties of the tube. By providing testing results, I can offer customers more precise information about the yield strength of the specific tubes they are interested in.
