Properties

Molybdenum rod （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.

Our molybdenum rods can be customized in size, please contact me and I will give you a satisfactory quote.

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.
