Molybdenum is gray-metallic and has the third-highest melting point of any element next to tungsten and tantalum. It is found in various oxidation states in minerals but does not exist naturally as a free metal. Molybdenum allows readily to form hard and stable carbides. For this reason, Molybdenum is frequently used for making steel alloys, high strength alloys, and superalloys. Molybdenum compounds usually have a low solubility in water. Industrially, they are used in high-pressure and high-temperature applications such as pigments and catalysts.
Standard: ASTM B387
Material: >99.95%
Density: 9.8~10.20g/cc
Molybdenum Bar Applications
Molybdenum bar is mainly used in drawing thin molybdenum wire, producing molybdenum electrode, and steel-making additives. Meanwhile, the molybdenum bar is also widely used in the furnace industry for radiation screens, elements, and sintering trays.
Molybdenum Bar Specifications
Molybdenum round bar is manufactured as random length pieces or cut to customers’ desired lengths in diameters ranging from 0.080 inches to 6.00 inches. Please view Molybdenum Rod to see our standard sizes of round bars. Below are most of the standard sizes of our molybdenum rectangular bars. If you do not see the size of the molybdenum bar you require, please feel free to contact us.

Surface Treatment of Molybdenum Bar
Black Surface – Surface is “as swaged” or “as drawn”. Retaining a coating of processing lubricants and oxides.
Cleaned Surface – Surface is chemically cleaned to remove all lubricants and oxides.
Machined or polished Surface – Surface is machined or polished to remove all coating and to achieve precise control.
Surface Condition of Molybdenum Bar
No super-fusion, bubble, flaw, layering, necking down, insertion and scratch etc.
