Molybdenum Rod Surface

  • Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.
  • Black: The surface is either as swaged or as drawn and retains a coating of processing lubricants and oxides.
  • Ground: The surface is center-less ground to remove all coating and to achieve precise diameter control.

How to remove the black oxide layer on the surface of the molybdenum rod?

  • Molybdenum products have the characteristics of easy oxidation. When heavy oxides need to be removed, use strong acids (fluoric acid, nitric acid, hydrochloric acid, etc.) to treat. Please pay attention to the operation.
  • Mild oxide with the addition of an abrasive cleaning agent, with a soft cloth or sponge, wipe, and then wash with warm water.
  • Cleaned molybdenum products will lose the metallic luster, please pay attention.

Molybdenum Rod/Bar Applications

  • Used to manufacture electric vacuum devices and electric light source parts.
  • Suitable for processing ion-implanted parts.
  • Used as the high-temperature heating element and high-temperature structural parts.
  • Used as the electrode of the furnace in the glass and refractory fiber industry. It works in 1300℃ molten glass and has a long life.
  • Used as an electrode in the rare earth industry.

Molybdenum Rod/Bar Packing

The Molybdenum Rods and Bars will be carefully packaged in wooden cases, with additional support from soft materials, to prevent any shifting or movement during transit.
