Introduction of aircraft aluminum

Edit: admin Date: 2017-06-28 16:32
Aircraft aluminum is an ultra-high strength deformation of aluminum alloy, is currently widely used in the aviation industry. It has good mechanical and processing performance, good solution after the plastic treatment, heat treatment to strengthen the effect is good. It is generally at 150 ℃ (or even higher) below the high strength and good toughness. It is the ideal structural materials.
Compared with ordinary aluminum, Aircraft with aluminum has a higher demand to the strength, hardness, toughness, fatigue resistance, plastic. As the aviation aluminum light weight, light weight effect is significant, and has replaced steel and occupy the dominant position of the current aviation materials. Aviation equipment on the aluminum requirements are higher, and is an important high-end aluminum application market.
There are many kinds of aluminum alloy used in aircraft. The aluminum alloy mainly used by aircraft structure in the world are 2 series of high strenth(2024 aluminum plate, 2A12 aluminum plate, etc.) and ultra-high strength of the 7 series (7075 aluminum plate, 7050 aluminum plate, 7A04 aluminum plate, etc.), and some 5 series aluminum plate(5A06 aluminum, 5052 aluminum, 5086 aluminum, etc.) and 6 series aluminum(6061 aluminum, 6082 aluminum, etc.) and a small amount of
other series of aluminum.

Aircraft aluminum is mainly used in the airfoil skin, airfoil girders, spindles upper and lower edges, webs, fuselage trusses, seat slides, keel beams, side frames, fuselage skin, fuselage lower wall Board, the main floor of the beam and other parts.
1, hard aluminum: aluminum magnesium copper alloy. The aviation industry is the most widely used aluminum alloy. Commonly used 2024,2A12,2017A, strength, toughness, fatigue resistance is better, good plasticity. Used to make skin, frame, ribs and so on.
2, super hard aluminum: aluminum zinc magnesium alloy. Commonly used 7075,7A09, the strength limit and yield strength is high, bear the load, used to make the wing on the wing surface skin, beams and so on.
3, rust-proof aluminum alloy: commonly used aluminum-magnesium alloy 5A02,5A06, 5B05. Has a high corrosion resistance, fatigue resistance, good plasticity, weldability. It is used to make mail, tubing and so on.
4、forged aluminum alloy, commonly used 6A02, high hardness, with good corrosion resistance. Manufacture of engine parts, joints and so on.
5、casting aluminum alloy, the proportion of small, corrosion resistance, high heat resistance, manufacturing engine casing and so on.
Mingtai Aluminum has the first academician workstation in the province, 313 technical research and development team, casting boutique to provide you with a full range of aerospace aluminum alloy.
