Nickel is a simple substance, ductile, malleable, transition metal of silver-white color, at ordinary temperatures in air it is covered with a thin film
of oxide. Chemically inactive. It belongs to heavy non-ferrous metals, it does not occur on the ground in its pure form - it is usually a part of various
ores, high hardness, well polished, ferromagnetically attracted by a magnet, is indicated by the Ni symbol in the periodic system and has 28 serial
The overwhelming majority of nickel is used to obtain alloys with other metals (fe, cr, cu, etc.), which are distinguished by high mechanical, anticorrosion, magnetic, or electrical and thermoelectric properties. In connection with the development of jet technology and the creation of gas turbine units, heat-resistant and heat-resistant chromium-nickel alloys are especially important. Nickel alloys are used in the construction of nuclear reactors.
A significant amount of nickel is consumed for the production of alkaline batteries and anti-corrosion coatings. Malleable nickel in its pure form is used for the manufacture of sheets, pipes, etc. It is also used in the chemical industry for the manufacture of special chemical equipment and as a catalyst for many chemical processes. Nickel is a very scarce metal and, if possible, should be replaced by other, cheaper and more common materials.
It is used in the manufacture of bracket systems (titanium nickelide), prosthetics. Widely used in coin production in many countries. In the United States, a 5-cent coin is colloquially nickel. Nickel is also used for the production of wrapping strings of musical instruments.
