Question

The metal Aluminium (Al) is widely used in industry. The usage of Al and its alloys ranks only second to ferrous (or iron) alloys. It is a strong metal whose density is one third of steel. It is also an excellent conductor of heat and electricity and resistive to corrosion. Pure aluminium exhibits good corrosion resistance due to the formation of a barrier oxide film that is bonded strongly to its surface. Hence, Al is known as Self-Protective metal. Why is Aluminium Paint applied to iron electric poles? * because Fe is a self protective metal because Al prevents corrosion of the iron poles due to the formation of a protective layer of Aluminium oxide because Fe prevents corrosion of the iron poles due to the formation of a protective layer of ferous oxide​

Answer 1

Answer:

yes it is strong metal whose density is 1/3 of steel
