Chemistry, Physical and Mechanical Properties of Molybdenum

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. To better aid you in your material evaluation and selection, Molybdenum's properties are listed.
