What kind of aluminum profile is the
aircraft aluminum extrusion profiles? What are the differences compared to ordinary aluminum?
Compared with ordinary aluminum profiles,
aircraft aluminum extrusion profiles have higher requirements on strength, hardness, toughness, fatigue resistance and plasticity. There are many kinds of
aircraft aluminum extrusion profiles.
1. Hard aluminum: aluminum magnesium copper alloy. The most widely used aluminum alloy in the aviation industry. Commonly used are 2024, 2A12, 2017A, strength, toughness, good fatigue resistance, good shape. Used to make skins, partitions, ribs, etc.
2. Super-hard aluminum: aluminum-zinc-magnesium-copper alloy. Commonly used are 7075, 7A09, high strength limit and high yield strength, and bear large load, used to make the wing upper skin and girders.
3. Anti-rust aluminum alloy: commonly used aluminum-magnesium alloy has 5A02, 5A06, 5B06. It has high corrosion resistance, fatigue resistance, good shape and weldability. Used to make fuel tanks, tubing, etc.
4. Forged aluminum alloy, commonly used 6A02, high hardness, good corrosion resistance. Manufacture of engine parts, joints, etc.
5. Cast aluminum alloy, small specific gravity, corrosion resistance, high heat resistance, manufacturing engine rafts, etc.
