Nickel was widely applied in various fields of industry. It is divided into several types: primary, semi-finished, nickel alloy. Each of these has a number of marks. They differ in chemical composition that defines their technological properties. Requirements for primary nickel GOST 849-97 sets. Nickel is the following marks: 0-H, H-1, H-1y, H-2, H-3 and H-4. Most often they are used for the manufacture of steel and alloying alloys. These grades differ in the percentage of nickel. More than just a

TNickel has submitted fewer - 99.93%. The H-3, for example, nickel should be at least 98.6% of the total weight..

Primary nickel is most often comes in the form of cathodes sliced / sheet sizes 1030h870h12 mm, and granules (typical for the brand H-3). Semi-finished nickel used for the production of wire, sheets, strips, rods and other products that are used in machine building and instrument making. The quality of these products each adjusts its GOST. For example, GOST 13083-77 - is the technical requirements for the production of rods, GOST 6235-91 - for sheets and strips. Among the semifinished nickel identify several brands: NP0Evi, NP1, NP1Ev, NP2, NP2E, NP3, NP4, NPA1, NPA2, NPAN. Mark NP0Evi, for example, is used for the manufacture of anodes and other components of electronic devices. Also it is used for the production of thin nickel ribbon (0.05-2 mm), which is widely used in manufacturing various equipment. Nickel mark NP1 is used for the manufacture of wire, which is later used for details of special purpose. These stamps nickel is also present in high purity (98,6-99,9%). They differ mainly impurities which determine their physical properties such as melting point, hot-working temperature, annealing, casting, and the coefficient of linear shrinkage.

Demand for nickel is increasing annually, and this is not surprising. It is no secret that the scope of the use of nickel becomes larger every year. In particular it concerns the manufacture of stainless steel. This process uses about two thirds nickel production worldwide. Due to their properties, nickel and widely used in engineering, electronics, power, manufacturing equipment for transportation as well as in the manufacture of glass. It should be noted that the use of nickel is more than 300 sectors. From producing nickel wire, sheets, strips, rods and powders.

The main advantages of nickel:

  • Nickel is highly resistant to mechanical stress;
  • a high level of heat resistance;
  • protects against aggressive chemicals. Let us consider a few key aspects of its production. There are several ways:
  • carbonyl, whereby one of its stages, this semifinished copper-nickel, and the level of sulfide compounds in the initial ore is very high;
  • aluminothermic method of Ni ore, while using the standard formula - 3NiO+2Al=3Ni+Al2O3;
  • recovery of coal dust, when they receive a nickel-iron pellets.

Industrial use of nickel:

  • Nickel is used in medicine, in particular, it relates to the manufacture of braces;
  • Nickel compounds are used for the production of precision mechanisms and instruments for measurement;
  • Nickel prevents corrosion, therefore, finds its application in the nickel plating of metals;
  • Production of coins and jewelry;
  • manufacture of dyes, coatings;
  • aviation and space industry.
