Aluminum Plate For Aircraft Structures

Aluminum plate for aircraft structures is super hard aluminum adopt high strength and high toughness aluminum and magnesium system as the base to add a small amount of other elements of special metal materials, commonly used 2024 aluminum plate, 2A12 aluminum plate, 2017 aluminum plate, 7075 aluminum plate etc., because of its extremely high hardness and toughness is very good, often used in aircraft structural parts, automobile body structural parts as well as the hull of the ship structural parts and so on. In addition, 6061 aluminum plate is also one of the commonly used aluminum alloys in the field of aviation, it has good corrosion resistance and excellent welding function, although its strength is moderately low, but there are still some applications in aircraft manufacturing.

At the same time, some specific types of aluminum plate for aircraft structures, such as 2024 aluminum plate (or 2A12 aluminum plate) and 7075 aluminum plate, they have the strength, toughness, fatigue resistance and good plasticity and other characteristics, and therefore commonly used in the manufacture of aircraft skin, spacer frames, wing ribs and other components, but also because of its excellent performance in the aircraft manufacturing occupies an important position. 2024 aluminum plate has high cracking toughness and low fatigue crack expansion rate, so it is often used as the material of the fuselage and the skin under the wing. Aluminum-zinc-magnesium-copper alloy, 7050 aluminum plate, 7075 aluminum plate, with better strength, resistance to peeling corrosion and resistance to stress corrosion function, has a high strength limit and yield strength, bearing load characteristics, so it is used to manufacture the wing of the upper airfoil skin, beams, and other key structural components, often used in the pressure-resistant components of the F-18 aircraft. 4A11 aluminum plate: this kind of aluminum alloy has a wide range of applications in aerospace field, commonly used in the manufacture of aircraft fuselage structure, aviation engine components, fuel tanks, aircraft components, etc., to meet the aerospace field on the lightweight and high strength requirements.

In addition, there are some other types of aluminum plate for aircraft structures, such as rust-proof aluminum alloy, forged aluminum alloy and cast aluminum alloy, etc., which also play an important role in the production of aircraft structure. Antirust aluminum alloy such as 5A02 aluminum plate, 5A06 aluminum plate, with high corrosion resistance, fatigue resistance, good plasticity and weldability, often used in the manufacture of fuel tanks, fuel pipes and so on. And forged aluminum alloy and cast aluminum alloy is because of its good hardness, corrosion resistance and heat resistance, often used in the manufacture of engine parts, joints and engine magazines.

Overall, aluminum sheet plays an important role in the manufacture of aircraft structures due to its light weight, high strength and good processing performance. It should be noted that, when selecting aluminum plate for aircraft structure fabrication, it is necessary to consider its strength, toughness, fatigue resistance, corrosion resistance, forming and processing performance and other factors to ensure the safety and reliability of the aircraft. At the same time, the specific type and specification of aluminum plate will also be selected according to the design needs of the aircraft, the use of the environment and flight requirements and other factors.
