Explanation:

Nickel does not occur free in nature and is found in association with copper, uranium and other metals.It is used as an important alloying material and when alloyed with iron, rust proof stainless steel of superior quality is obtained, from which utensils are made. Because of its greater hardness and tensile strength nickel steel is used for manufacturing armoured plates, motor cars, bullet jackets and naval construction.When alloyed with copper or silver, it is used for making coins. Nickel-aluminium alloys are used for manufacturing aeroplanes and internal combustion engines.Most of the reserves are found in Orissa, Jharkhand, Rajasthan, Karnataka, Nagaland, Jammu and Kashmir and Kerala.
