Properties

 *If the diameter is <0.125”, please check our Molybdenum wire.

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.

Please view molybdenum rod to see our standard sizes of round bars. The above are most of the standard sizes of our molybdenum rectangular bars. If you do not see the size of the molybdenum bar that you require, please feel free to contact us.

 

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.
