India is blessed with considerable quantity of titanium based mineral resources accounting to about 20% of the world's availability holding and third largest reserves. The main titanium minerals are ilmenite and rutile available in beach sand deposits in the coastal states like Kerala with production of about 0.6 MT by mining & mineral separation process to provide environmental friendly titanium alloys. Though the major usage of titanium alloys are for aeronautics, defense, space, atomic energy sectors, its usefulness with special properties is yet to be exploited for the Indian automotive sectors. The principle advantages of Titanium alloys for automotive application that can be exploited are - 45% lighter than steel, virtually total resistant to acidic attack, four times more corrosion resistance than stainless steel, high specific strength, good ductility and ease to form by forging and machining operations.
