ALUMINIUM IS USED IN THE MANUFACTURE OF AIRCRAFT BECAUSE IT

• A. Is hard and brittle
• B. Is light and resists corrosion ✓
• C. Has high density and conducts electricity
• D. Is malleable and ductile

Aluminium is chosen for aircraft construction due to its advantageous properties. Firstly, aluminium is lightweight, which helps reduce the overall weight of the aircraft, leading to improved fuel efficiency and performance. Additionally, aluminium has a high strength-to-weight ratio, making it ideal for withstanding the stresses and strains experienced during flight. Furthermore, aluminium naturally forms a protective oxide layer on its surface, which provides excellent corrosion resistance, crucial for ensuring the longevity and safety of aircraft components.
