Background Information

Like tungsten, molybdenum is one of the refractory metals. It does not have the density of tungsten, but still has a relatively high melting point and is somewhat easier to machine. Midwest Tungsten Service provides molybdenum in rod, sheet, and bar. We also provide material trays, heat shields, nuts, and threaded rod for the vacuum furnace industry, as well as glass melting electrodes and vacuum evaporation boats.

Molybdenum Advantages

  • High melting point

Molybdenum Applications

  • Vacuum furnace hardware

Need Custom Raw Material Sizes or Machined Parts?

We can custom make any parts from your dimensioned print or raw materials like rods, disks, sheets, plates, bars, or wire.

Have Technical Questions?

We’re available to answer any questions regarding our products or services and provide quotes for custom projects. We look forward to hearing from you.
