The aluminum tensile strength is an important mechanical property parameter that describes the ability of an aluminum material to resist damage during tension. Its value will be affected by a variety of factors such as the type and purity of aluminum alloy, heat treatment state, manufacturing method and so on. Generally speaking, the tensile strength of pure aluminum is between 80 and 100 MPa. However, aluminum alloys that have been heat-treated or alloyed usually have higher yield strengths. For example, certain aluminum alloys can have tensile strengths of 300 MPa or more. For example, rustproof aluminum 5A50 has a tensile strength of 265 MPa, 3A21 aluminum has a tensile strength of less than 167 MPa, duraluminum 2A11 has a tensile strength of 370 MPa, and 2A12 aluminum has a tensile strength of between 390 and 420 MPa. In addition, the tensile strength of aluminum sheet materials of different densities and thicknesses may also vary considerably.

The tensile strength of common aluminum alloys varies depending on their alloy composition and manufacturing process. Below is a range of tensile strengths for some common aluminum alloys:
5083 Aluminum Alloy:
This is a commonly used high-strength aluminum alloy that can have a tensile strength of approximately 280 MPa.
6061 Aluminum Alloy:
This is a common medium-strength aluminum alloys, with a tensile strength of about 310 MPa, which is among the upper-middle levels of aluminum alloys. this alloy has excellent corrosion resistance and weldability, and is widely used in automotive parts, aerospace, and other applications.
7075 Aluminum Alloy:
This is a high-strength aluminum alloy with a leading tensile strength among common aluminum alloys, reaching about 570 MPa. This alloy has good strength and rigidity, and is widely used in aerospace, sports equipment and other fields.
2024 Aluminum Alloy:
This is a medium-strength aluminum alloy that can reach a tensile strength of about 450 MPa.
Overall, the aluminum tensile strength is a complex and variable parameter, and these values are only approximate reference ranges. The specific tensile strength will also be affected by a variety of factors such as temperature, strain rate, grain structure, and so on. Therefore, for aluminum plate materials that need to accurately measure the tensile strength, the universal testing machine should be used to test in order to obtain accurate values. In addition, in addition to tensile strength, the hardness, corrosion resistance, weldability and other properties of aluminum alloy are also important indicators for assessing its applicability. When selecting aluminum alloys, these properties as well as specific application requirements need to be considered comprehensively.
