उत्तर

A common metal which is highly resistant to corrosion is aluminium.

Explanation:

Aluminium is highly resistant to corrosion because it reacts rapidly with oxygen in the air to form a thin, tough, protective layer of aluminium oxide on its surface. This invisible oxide layer adheres tightly to the metal and prevents further oxygen or moisture from reacting with the fresh aluminium beneath.
