molybdenum price sheet buy rod bar electrodeMolybdenum - refractory silver metal. The name comes from the Greek metal molybdos - translated as "Lead" (molybdenum looks like lead). Molybdenum - chem. element (Mo) VI of the periodic table. Atomic number 42. Density - 10.22 g/cm3, melting point - 2620 ° C.
In the atmosphere at ordinary temperatures molybdenum hardly susceptible to oxidation. Molybdenum does not react with hydrogen. Molybdenum oxidized at 400 °C.

Molybdenum in the steel industry only started to use at the end of XIX century. Molybdenum is used with the rubbing parts, which operate at temperatures from -45 to +400 ° C. In the free form in nature does not exist.


  • Heat-resistant;
  • High specific strength;
  • High elasticity;
  • The low thermal expansion;
  • Corrosion-resistant (alkaline and acid solutions).


  • Creep;
  • Brittle welds;
  • Non-elasticity at low temperature;
  • The high price of the material.


Mostly molybdenum is used as an additive to a variety of metals and alloys. The main property of molybdenum - heat resistance. Molybdenum in steel cause simultaneous increase hardness and toughness, improve hardenability steel amplifies heat resistance. Molybdenum alloys are indispensable in aviation and automotive industries. Molybdenum is also used in the chemical industry due to good acid resistance. Molybdenum is also used in glass and ceramics industry.

Molybdenum - refractory metal. Used in the production of missiles and aircraft skin. Also used in the manufacture of honeycomb panels of spacecraft, heat exchangers, heat shields. Molybdenum - an acid-resistant metal. Can operate in hostile environments (sulfuric, hydrochloric and phosphoric acid). Molybdenum is the main structural material in the manufacture of filaments for electric lamps and cathodes for vacuum tubes.
