Alloy high duralumin sheet aviation grade 7A09
Aviation grade 7A09 alloy high duralumin sheet：7A09 aluminum alloy sheet belongs to the 7 series (Al-Zn-Mg-Cu) alloy, which is an ultra-high strength deformed aluminum alloy. It has excellent combination of properties such as high specific strength, fracture toughness and thermal conductivity. The superior properties of this aluminum alloy make it an ideal materials for aircraft and automotive applications. Through proper T6 aging treatment, the material can reach its peak strength, and has good resistance to exfoliation and corrosion. It has been acknowledged that corrosion resistance of aluminum alloy depends on the formation of passive film on its surface. The composition ratio of 7A09 is higher than that of 7A04 aluminum sheet. The static fatigue, notch sensitivity, and stress corrosion resistance of the sheet are better than 7A04. 7A09 aluminum sheet is used in the aerospace industry with high strength, good weight reduction, and improved aircraft safety.

| 7A09 aluminum sheet is widely used in the aviation industry and used to manufacture various important parts. 7A09 aluminum is used for aircraft skins, wall panels, bulkheads, front beams, ribs, joints, pillars and landing gear, cylinder hydraulic systems, hydraulic oil tanks with movable rods, outer tubes and other key components. The light weight of aluminum can reduce the weight of the aircraft, but this does not affect the safety of the aircraft, and it can even be improved.Other applications, such as mold, beauty equipment, notebook shell, etc. | |||||||||
