What is the Boeing 747 made of?

The Boeing 747 is primarily constructed from aluminum, which is used for the fuselage, wings, and tail due to its lightweight and strength properties. Additionally, composite materials, such as carbon fiber reinforced plastics, are used in some parts, particularly in the wing structures, to enhance performance and reduce weight. The aircraft also incorporates various metals, including titanium and steel, for critical components like the landing gear and engine mounts.
