Metal cobalt

Technical characteristics

Cobalt is classified as heavy metals (such as atomic weight and density). In the periodic table the periodic table is denoted by the symbol Co In the photo cobalt is a bluish-gray, lustrous ingot This item contains more than 30 minerals. Get it mostly from Nickel ores, processing them with solutions of sulfuric acid or ammonia. Basic mechanical properties of the metal represented by the following parameters:

  • the melting point is 1495 °C;
  • boiling point — 2957 °C;
  • thermal conductivity is 100 W/(m*K).

It should be noted that this metal is ferromagnetic and this property defines one of the main areas of its application. First and foremost we are talking about the cores of motors and transformers. In addition, it is used in the manufacture of permanent magnets


Cobalt compounds known to man since ancient times. Blue cobalt glass, enamel, paint find in the tombs of Ancient Egypt. Cobalt in the form of a dopant used in the production of steel with high demands on performance. Alloys with cobalt, they obtained an excellent reputation in the manufacture of high strength tools (drills, cutters, etc.). High speed tool, which doped with cobalt is characterized by high parameters:

  • heat resistance;
  • durability;
  • toughness;
  • corrosion resistance in aggressive environments.
