nickel (Ni)

Nickel (Ni) is a natural element, which has the atomic number 28 in the periodic table of the elements and belongs to the elements of the nickel group. In nature, it occurs as a white powder.

Since nickel has good electrical conductivity, it is used in many electrical applications. For example, in NiCd batteries and NiMH batteries, as a base material for conductors, in field plates, in thermocouples and resistance thermometers, in the magnetic material permalloy, in relays and their contact surfaces where the abrasion resistance of nickel is important, in connectors, and much more.
