Question

Fill in the blanks
A metal used for making aircraft ________.

Answer 1

• Aluminium is the metal used for making aircraft.
  
• The modern Boeing 747 is an aluminum airplane as well. Other metals, such as steel and titanium, are sometimes used to build aircraft. Steel is heavy though, so not too much is used. Titanium is almost as strong as steel, has a medium weight, is heat resistant, and is corrosion resistant.
