In the application of aluminum alloy materials, selecting appropriate high-strength aluminum alloys is crucial for manufacturing load-bearing structures. Different series of aluminum alloys exhibit varying performances in load-bearing structure manufacturing due to their chemical compositions and properties.

7000 series aluminum alloys are currently among the highest-strength aluminum alloy categories, with 7075 aluminum alloy being the most typical. It uses zinc as the main alloying element, strengthened by adding magnesium, copper, and other elements. After heat treatment, its tensile strength can exceed 560 MPa, with excellent hardness and fatigue resistance. It is widely used in aerospace, automotive manufacturing, and other high-strength load-bearing structures, such as aircraft girders, landing gear, and automotive suspension systems. If you need high-strength aluminum rods or plates for manufacturing critical load-bearing components, 7075 aluminum alloy is a worthwhile consideration.

2000 series aluminum alloys, with copper as the main alloying element, are represented by 2024 aluminum alloy. It has high strength (tensile strength of approximately 470 MPa), good toughness, and excellent machining performance. It is commonly used to manufacture load-bearing components such as aircraft skins and structural frames, with extensive applications in the aviation industry. If you require aluminum plates for machining complex load-bearing parts, 2024 aluminum alloy is an excellent choice.

6000 series aluminum alloys, such as 6061 aluminum alloy, use magnesium and silicon as the main alloying elements. They offer good comprehensive performance, moderate strength (tensile strength of about 200–300 MPa), excellent corrosion resistance, and weldability, making them easy to process and form. In construction, bridges, and vehicle manufacturing, 6061 aluminum alloy is often used to manufacture load-bearing frames, supports, and other structures, such as aluminum profile frames in construction and automotive body frames. If your load-bearing requirements for aluminum pipes or plates are not at the ultra-high-strength level and you value processability and corrosion resistance, 6061 aluminum alloy is a suitable option.
