Nickel (or nichelio) is a chemical element with atomic number 28. Its symbol is Ni.
Its name derives from the Swedish name Nickel, short for Nicolaus, and anciently associated with a person of little worth, goblin or restless boy, full of life. There is also the German derivate Kupfernickel ("devils copper"), name given by miners of this element once considered without value.
Nickel is a white silver metal. It belongs to the iron group, it is hard, malleable and ductile.
Nickel is one of five ferromagnetic elements. It is often accompanied by cobalt: both can be found in meteoric iron. It is rather appreciated for the properties it gives to metal alloys in which it is part. Due to the specific alloy used, the American coin known as "nickel" 2] (nickel) it is not ferromagnetic, whereas the equivalent Canadian one used to be, until the coinage 1958 year.
Nearly 65% of nickel in the western world is used to make austenitic stainless steel; another 12% is used for super alloys. The remaining 23% needed is divided into other types of steel, rechargeable batteries, catalyts and other chemical products, coining), foundry products and coatings.
Due to its optimal resistance to oxidation, the use of nickel is found in:
stainless steel and other alloys which are resistant to corrosion
nickel steel, used in low temperatures processes
alnico, an alloy used in magnets
mumetal, that has an especially high magnetic permeability, which is used to shield magnetic fields
monel, which is a nickel alloy highly resistant to corrosion, used in ship propellers, cooking equipment, and chemical industrial plants
Aaloys with shape memory, such as nitinol, used in robotics and in orthodontics (a branch of dentistry)
rechargeable batteries, such as metal nickel-
coining: In the United States and in Canada nickel is used in the one-
chemical lab crucible pots
hydrogenation of vegetable oils: in this case, nickel is finely pulverized and becomes a catalys;
iron, brass, and other metal material coatings
some alloys, German silver, for example
