7075 aluminum plate belongs to Al Zn mg Cu super hard aluminum, which is used in aircraft manufacturing industry. After solution treatment, it has good plasticity, especially good heat treatment strengthening effect, high strength below 150 ℃ and especially good low temperature strength, poor welding performance, stress corrosion cracking tendency, and needs to be used by aluminum cladding or other protective treatment. The performance is better than 7A04, among which the 7075-T651 state is the best, known as the best aluminum alloy products, high strength. The alloy has good mechanical properties and anodic reaction, and is a typical aluminum alloy material for aerospace and military industry.

Properties of 7075 aluminum plate
Tensile strength: 524mpa 0.2% yield strength: 455mpa elastic modulus E: 71gpa hardness: 150HB density: 2.81g/cm ^ 3
7075 aluminum plate is a cold treatment forging alloy with high strength and hardness. 7075 aluminum plate belongs to Al Zn mg Cu super hard aluminum, which has good corrosion resistance, mechanical properties and anodic reaction. It is a typical aluminum alloy material for aerospace and military industry. The fine grain makes the deep drilling performance better, the tool wear resistance enhanced, the thread rolling more different, the density requirement is smaller, the hardness requirement is higher.

Advantages of Chinalco manufacturers
If the customer cuts the aluminum sample with specified specification, the cost will be calculated and the cost will be refunded for batch order. The company provides aluminum material sample free of charge, and does not specify the size. (postage to be paid by yourself)
Control product quality from the source:
All casting machines adopt the latest generation of semi continuous low liquid vertical casting technology of Wagstaff. It is equipped with ABB's electromagnetic stirring, on-line hydrogen measurement and on-line slag measurement system. Novelis online degassing system in France, deep bed filtration system, plate filter and tubular filter of Mitsui metal in Japan are used for on-line treatment of aluminum melt. The degassing efficiency reaches 0.12ml/100g-al, and the filtration efficiency reaches 98% or higher (the impurity is less than 10 μ m).
Aluminum surface quality control:
French sermas double head sawing machine can simultaneously cut head and tail at a maximum speed of 10 pieces per hour. Milling machine is the most advanced high precision and high rigidity design model of shingang company in Japan. Milling machine and sawing machine are arranged in series. After sawing the slab, the head and tail are directly transferred to the 1 milling machine through the roller table for up and down milling, and then the ingot device is automatically turned over, and the 2 milling machine completes the milling of the other side. The efficiency of sawing and milling is greatly improved.
Quality control of hot rolled coil：
SMS (1 + 4) 2560mm hot rolling line is adopted in the hot rolling project. The production capacity of hot-rolled can is more than 760kt / A, the maximum strip width is 2400mm, and the minimum thickness is 1.8mm. Siemens has advanced electrical configuration, on-line equipped with German IMS crown meter, and realizes the closed-loop control of thickness and shape.
Roller quality control：
German Hercules grinding machine adopts automatic grinding technology, has adaptive control ability, and is equipped with a special system for generating advanced roll shape. It can realize continuous measurement and on-line inspection under high requirements. The automatic CNC control in the grinder configuration can detect and repair the roll shape on line, and the control precision is 0.00001mm.
Quality control of cold rolling products：
The cold rolling project adopts German SMS 2500mm single stand CVC cold rolling mill and 2500mm double stand CVC cold rolling mill. The maximum strip width is 2400mm and the minimum strip width is 900mm. The coil size is 2750mm and 1200mm respectively. The maximum rolling force is 20000kn and the maximum rolling speed is 1800m / min. It is equipped with Danieli 2300mm trimming machine and Slitter in Germany, Engle straightener in Germany, Herkules grinder in Germany, POSCO packaging line in Korea and vollert elevated warehouse in Germany.
Is 6061 or 7075 aluminum stronger?
Alloy composition is different, 7075 aluminum plate belongs to superhard aluminum plate, hardness is much higher than 6061.
Different uses, 6061 alloy aluminum plate requires a certain strength, weldability and high corrosion resistance of various industrial structures, such as manufacturing trucks, tower buildings, ships, trams, furniture, mechanical parts, precision processing pipes, rods, shapes and plates. 7075 aluminum plate is used to manufacture aircraft structure and other high stress structural parts and dies with high strength and corrosion resistance.
The price is different. The price of 7075 aluminum plate is much higher than that of 6061 aluminum plate.
