Aerospace aluminum profile is a kind of super wide compressive strength deformed aluminum alloy profile, which is now used in aerospace industry. It has good structural mechanics and production and processing characteristics, good plastic deformation after aging treatment, good use after tempering treatment, usually under 150 ℃ (or higher) with high compressive strength and good ductility, and is an ideal structural raw material.

Compared with general aluminum alloy profiles, aluminum alloy profiles used in airports have higher requirements on compressive strength, strength, ductility, fatigue mitigation and plastic deformation. Because the aluminum profile of airlines is light in quality and effective in light in weight, it has already replaced the stainless steel sheet and occupied the leading position of aviation materials. As the key high-grade application store of aluminum profile, the weapon equipment of airlines has a high regulation on aluminum profile.

There are many kinds of aluminum alloy profiles used in airplanes. At present, the key of aluminum alloy profiles for airport construction of airlines in the world is 2 series (2024, 2017, 2A12, etc.) with high toughness and 7 Series (7075, 7475, 7050, 7A04, etc.) with ultra wide compressive strength. Another series includes 5 Series (5A06, 5052, 5086, etc.) and 6 Series (6061, 6082, etc.) and a small number of other products.

Aerospace aluminum profiles are mainly used in wing skin, wing stringer, upper and lower left and right edge strips of wing beam, web, shell stringer, seat guide rail, main keel beam, side frame, shell skin, lower wall panel of shell, main wood floor stringer, etc.

1. Duralumin: aluminum magnesium alloy copper. Aluminum alloy profiles are widely used in shipping industry. 2024, 2A12, 2017A are common, with good compressive strength, ductility, fatigue relief and plastic deformation. It is used to produce skin, partition frame, wing rib, etc.

2. Super hard aluminum: aluminum zinc magnesium alloy copper. 7075 and 7A09 are common, with high strength limit and tensile strength, and large load bearing capacity. They are used to produce wing skin, roof beam, etc.

3. Antirust aluminum alloy profile: common titanium magnesium aluminum alloy 5A02, 5A06, 5B05. It has high corrosion resistance, fatigue relief, excellent plastic deformation and welding performance. It is used for manufacturing e-mail box, oil pipeline, etc.

4. Forged aluminum alloy profile, common 6A02, has high strength and excellent corrosion resistance. Production and manufacturing of engine parts, connectors, etc.

5. Aluminum alloy casting, small proportion, corrosion resistance, high temperature resistance, production and manufacture of diesel engine case.
