Oxygen of air attacks iron as well as aluminium, then why aluminium is
considered better than iron for a number of purposes?


Answered by ashneybundela


Most metals corrode. ... At the other end of the spectrum is gold and the other precious metals which resist corrosion and form only very thin oxide layers or do not react at all with water and oxygen. Like most other metals, aluminium and iron react relatively slowly to form oxides and corrode.

aluminium is less reactive metal . although oxygen of air attacks Aluminium and iron both but Al does not get rusted . besides this Al is the lightest metal so Al is considered for a no. of purposes like making aeroplane wings , different utensils , windows , foil for food preservation etc
