I am going to describe the uses of aluminium and the uses of titanium.

Low density and doesn't CORRODE easily are the main properties of aluminium!

Aluminium in the air – the commercial aviation industry would never have succeeded without aluminium. Road transport- aluminium absorbs kinetic energy it is used extensively for the hummer vehicle and the off road land rover. Aluminium in building- all kinds of aluminium products are used in home construction and residential reinvasion. Aluminium in cooking-around half the cookware sold globally each year is made of aluminium.

Titanium is a transition metal. It has high strength, low density & good resistance to corrosion.

Titanium & its alloys have proven to be technically superior & cost-effective materials of construction for a wide variety of aerospace, industrial, marine & commercial applications. In north America approximately 70% of the titanium consumed is utilised for aerospace applications. Due to the expansion of existing applications and the development of new uses, the great growth occur in the industrial, marine and commercial sectors.
