Molybdenum is a refractory metal that is very useful in many industrial processes and applications that would not be possible with many of the more common metals and alloys. Refractory metals and alloys are extraordinarily resistant to heat and have unique physical properties.

Application areas
In the missile industry Molybdenum is used for nose cones, high temperature structural parts, nozzles, leading edges of control surfaces, support vanes, re-entry cones, and heat radiation shields. In electronics Molybdenum is used for cathodes, magnetron end hats, x-ray tube components, filaments, and glass-to-metal seals. In high-temperature applications Molybdenum is used for: furnace windings, structural furnace members, and containers for components exposed to high temperatures.
