Molybdenum is both very hard and very soft, which has more toughness than tungsten. Molybdenum has a high modulus of elasticity, ranging from 0.090 inches to 3 inches, so it is listed as molybdenum plate. Molybdenum plate is widely used in mold and parts furnace construction, electronics and semiconductor industry components manufacturing.

  When the satellite is returned to the atmosphere, it must overcome the hot gas scour. Therefore, it is required to withstand vibration, shock, vacuum, radiation and temperature alternating environments. Molybdenum based alloys are usually used to make the skin of satellite recovery cabin stability skirt. The TZM molybdenum alloy is also used to make the nozzle of the solid fuel rocket engine of the space rocket or the space shuttle, the nose cone of the rocket, the front edge of the aircraft, the rudder, the heat shield, the honeycomb structure, etc.

  The weapon industry not only uses molybdenum steel as a tank armor, but also uses the corrosion resistance of TZM and TZC molybdenum alloy, which is used as a whole turbine impeller of cruise missile, and is also used as a difficult helium turbine impeller with high temperature gas cooled atomic reaction.

   The electronic industry often uses the advantages of high melting point of molybdenum, low expansion coefficient and low electron emission rate of two times. It is widely used as the grid of various electronic tubes, screen pole and the leading line of the power source of high electric light source. Now, the study shows that adding a small amount of silicon, aluminum and potassium to molybdenum makes it two times higher than pure molybdenum at 700 C. It reaches 1800~1900 degrees, and is widely used as heating element and heat shield.

   Corrosion resistance of molybdenum is often used in chemical industry. Molten glass can corrode most metals, but molybdenum and platinum are resistant to corrosion. Platinum is too expensive. Nowadays molybdenum or tungsten alloy containing 30% tungsten is used instead of platinum as the electrode of glass melting furnace. Melting and holding molten metal: 1059 centigrade lead, 1430 centigrade bismuth, 999 C lithium, 599 C mercury, 899 centigrade potassium and sodium, 850 centigrade zinc. At this time, the corrosion resistance and high temperature strength of molybdenum determine that it is the best material choice and has been widely used.   molybdenum based alloys are widely used in the manufacture of sulphuric acid heat exchangers and valves.
