Overview of 7075 Aluminum Tube
7075 aluminum tube is a high-strength aluminum alloy tube widely applied in aerospace, military equipment, automotive engineering, and high-performance sports equipment. The 7075 aluminum alloy is primarily composed of aluminum, zinc, magnesium, copper, and trace elements. Through a combination of cold working and heat treatment processes, it achieves outstanding mechanical performance along with reliable corrosion resistance.
In terms of mechanical properties, 7075 aluminum tube significantly outperforms many conventional aluminum alloys. Compared with 6061-T6 aluminum tube, its strength is nearly double, making it especially suitable for applications involving heavy loads and high stress.

With an excellent strength-to-density ratio, 7075 aluminum is highly favored in weight-sensitive applications such as aerospace.
Low Plasticity and Limited High-Temperature Strength
The alloy has relatively low plasticity and is not recommended for long-term use in high-temperature environments; optimal performance is typically below 120°C.
Good Machinability
Suitable for milling, turning, drilling, and other conventional machining processes, enabling the production of complex components.
Improved Corrosion Resistance with Surface Treatment
Although its inherent corrosion resistance is lower than some other aluminum alloys, anodizing and other treatments significantly enhance durability.
High Toughness After Treatment
Cold working and heat treatment improve toughness, reducing the risk of fracture under impact or cyclic fatigue loads.
Typical Chemical Composition of 7075 Aluminum Tube
The alloy consists primarily of aluminum, with controlled additions of zinc, magnesium, copper, and chromium. Minor amounts of silicon, iron, manganese, titanium, and other elements are present within standard limits, with aluminum forming the balance.
