UsageManufacturing, Construction

Molybdenum, a refractory metal is widely used as an alloying element. Due to its good thermal and electrical conductivity, high melting point and excellent strength at elevated temperatures, molybdenum can be used for various applications in its pure form. In addition, molybdenum has low thermal expansion coefficient. It has to be protected by a suitable coating to withstand temperatures above 500°C under an oxidizing environment.

The following section will explain in detail about molybdenum.

Other Designations

Other designations that are equivalent to molybdenum include the following:

  • ASTM B386
  • ASTM B387
Thermal Properties

The thermal properties of molybdenum are outlined in the following table.

PropertiesMetricImperial
Thermal expansion coefficient (@20°C/68°F)5.35 µm/m°C2.97 µin/in°F
Thermal conductivity138 W/mK958 BTU in/hr.ft².°F
Fabrication and Heat Treatment Machinability

Machining molybdenum is similar to that of cast iron. Molybdenum tends to tear if positive feeds are not employed.

Forming

Molybdenum can be efficiently formed while bending in a transverse direction or against rolling or grain direction. The workpiece can be heated before forming to avoid cracking.

Welding

Molybdenum can be welded using electron beam methods and other resistance methods in helium or argon atmosphere.

Annealing

Annealing of molybdenum can be performed at 1149°C (2100°F).

Applications

The following are the major applications of molybdenum:

  • Heating elements in furnaces
  • Filament supports in electric lamps
  • Heat shields
  • Hearth trays, plates and racks
  • Missile and aircraft parts
  • Boring bars
  • Thermocouples
  • Nuclear energy applications
