The 7075 aluminum tube should be used as a stress component under normal temperature and below 120 °C. Aluminum alloy is easy to produce and process, and has good corrosion resistance and high ductility. This aluminum alloy is commonly used in the aviation and aerospace industries and has become one of the key construction raw materials in this industry.
Zinc is the key aluminum alloy element in 7075 aluminum tube. Adding magnesium to the aluminum alloy containing 3%-7.5% zinc can produce MgZn2 with significant strengthening effect, making the actual effect of the heat treatment process of the aluminum alloy far better than that of aluminum. - Zinc binary aluminum alloy. By increasing the zinc and magnesium components in the aluminum alloy, the compressive strength will be further improved, but the working ability of its resistance to intergranular corrosion and anti-stripping corrosion will decrease with it. Withstand the heat treatment process, can achieve very high compressive strength characteristics. The raw materials of 7075 aluminum pipes are generally added with a small amount of copper, chromium and other aluminum alloys. Among this series, A7075-aluminum alloy profiles are especially good products, known as high-quality products in aluminum alloy profiles, with high compressive strength, far exceeding all alloy steels .
5052 aluminum alloy belongs to the Al-Mg series alloy, which is widely used, especially the construction industry cannot do without this alloy, and is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, and moderate strength. The main alloying element of 5052 aluminum alloy is magnesium, which has good formability, corrosion resistance, weldability, and medium strength. Rivets, hardware products, electrical-apparatus shells, etc.
7075 aluminum alloy is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 aluminum alloy is one of the strongest alloys commercially available. Normal corrosion resistance, good mechanical properties and anodic reaction. The finer grains provide better deep drilling performance, enhanced tool wear resistance and differentiated thread rolling. Its main physical properties: tensile strength 524Mpa, 0.2% yield strength 455Mpa: elongation 11%, elastic modulus E/Gpa: 71, hardness 150HB, density: 2810.

5052 aluminum tube is AL-Mg series, which is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance: high plasticity and corrosion resistance, cannot be strengthened by heat treatment, and hardened in semi-cold work. It has good plasticity, low plasticity when cold work hardening, good corrosion resistance, good weldability, poor machinability, and can be polished.
Tensile strength (σb): 170～305MPa Conditional yield strength σ0.2 (MPa)≥65 Elastic modulus (E): 69.3～70.7Gpa Annealing temperature: 345℃.
7075 aluminum tube is one of the aluminum alloy profile pipe fittings with high strength and compressive strength in the current aluminum alloy profile coffin. pipe fittings. The 5052 aluminum alloy profile is a rust-proof treated aluminum alloy material. The strength and compressive strength of the 5052 aluminum alloy pipe is lower than that of the 7075 aluminum pipe, but it has excellent corrosion resistance and anodized treatment characteristics.
The strength and compressive strength of 7075 aluminum alloy pipes are far higher than 5052 aluminum alloy pipes, which is mainly determined by their distinctive composition. The 7xxx series of aluminum alloy pipes are mainly used for various airline parts, high-toughness machinery and equipment. Manufacturing, hardware products, second-class pressure vessels, outdoor sporting goods and other industries. The 5052 aluminum alloy pipe can be used for chemical plants, ships, automobile fuel tanks, automobile gasoline or grease hoses, various liquid vessels and other small load parts made by deep drawing. Next, the 7075 aluminum tube has excellent machinability, while the 5052 aluminum alloy tube has relatively weak machinability and can be polished and processed. The anodic oxidation treatment and electric welding characteristics of 7075 aluminum pipe are weak, which are mainly determined by its special composition, while the 5052 aluminum alloy pipe has excellent anodization treatment and electric welding characteristics.
