Molybdenum Rod/Bar, Mo


New product

Molybdenum rod and molybdenum bar are formed by sintering molybdenum powder. Molybdenum rod has a high melting point, good thermal conductivity, and low thermal expansion performance. It can be used to manufacture electric vacuum devices and electric light source parts, and can also be used as high-temperature heating elements, high-temperature structural parts, electrodes, etc.

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.

Surface Oxide Removal Method

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

Molybdenum Rod 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 and Molybdenum Bar Packing

The Mo rod and Mo bar will be packed in a wooden case supported with soft materials to ensure that the products thus packed will not shift inside the cases.
