Why are Aluminium and Titanium useful?
They have low densities and are resistant to corrosion.
1 of 10
Describe what happens when aluminium reacts with oxygen.
Aluminium reacts with the oxygen in the air and creates a layer of aluminium oxide that coats the metal.
2 of 10
What does this aluminium oxide layer prevent?
Prevents further corrosion.
