Compared to aluminum alloy for aircraft and ordinary aluminum alloy, the strength, hardness, toughness, fatigue resistance, plastic has higher requirements. Aluminum alloy used in the plane has a lot of types.
1, aluminum: aluminum magnesium alloy of copper. Aluminum alloy is most widely applied in the aviation industry. Commonly used 2024, 2A12, 2017A, strength, toughness, fatigue resistance is good, good plasticity. Used to make skin, frame, rib etc..
2, super duralumin: Al Zn mg Cu alloy. Commonly used 7075, 7A09, the ultimate strength and the yield strength is high, bear large load, to skin, making the wing upper surface of the wing beam etc..
3, rust proof aluminum alloy: commonly used aluminum magnesium alloys 5A02, 5A06, 5B05. Has high corrosion resistance, fatigue resistance, good plasticity and weldability. Used in the manufacture of mailbox and tubing.
4, forged aluminum alloy, common 6A02, high hardness, good corrosion resistance. Manufacturing of engine parts, connector etc..
5, cast aluminum alloy, the proportion of small, corrosion resistance, high heat resistance, making the engine casing etc..
