This is true that aluminium is a highly reactive element but it has a property of non-corrosion. That's why it is used to make cooking utensils.

The property comes from the fact that aluminium reacts with oxygen and forms a thin layer of aluminium oxide which acts a protective coating layer to resist further corrosion.
