Upper surface wing skin is usually made from
- 5056.
- 2024.
- 7075.
Explanation
The upper wing skin is loaded primarily in compression in flight, so it is normally made from 7075 aluminium alloy, which offers high compressive strength. Lower wing skins, which work mainly in tension and fatigue, typically use 2024 for its better fatigue and crack-growth properties, while 5056 is a wire/rivet-type alloy not used for skins.
