Question
Why is aluminium widely used in aircraft construction?
Solution
• Aluminium is chosen for aircraft primarily because it has a high strength-to-weight ratio. Being lightweight reduces the fuel required for flight and increases payload capacity. • It also possesses excellent corrosion resistance because it naturally forms a thin, protective layer of aluminium oxide when exposed to air. • It is highly ductile and easy to manufacture into complex shapes like wings and fuselage sections.
