Cronstedt discovered Nickel in 1751. Nickel is commercially obtained from pentlandite and pyrrhotite in Sudbury, Ontario, which produces 70% of the Nickel in the World. It is also found in niccolite and in most meteorites. Nickel steel is used for armour plates and burglar-proof vaults and in rust-resistant alloys. Nickel is also used in coinage. [LM] {RW}
