Nickel is a silvery white metal, endowed with qualities such as ductility (physical property of a material to withstand plastic deformation under the action of a finished load, without the risk of fracture or breakage) or flexibility (ability to be molded by deformation), with high mechanical resistance to corrosion and oxidation even having a isometric oxidation system (i.e., a disposed form that shows equal distance amongst its various points), being the nickel worth a position amongst the so-called "transition metals" in the periodic table.
