Hi students!
Try to solve the questions yourself with the information providing below: Aluminium is a corrosion resistant metal by the fact that it can make a layer of aluminium oxide under the presence of environmental factors. The layer is attached to the aluminium surface. On the other hand, anodizing is done to make the aluminium more resistant and stronger. Moreover, anodizing increases lubrication and adhesion from which the metal and alloy become more useful.
