Molybdenum Rod and Molybdenum Bar

Molybdenum Rods and Bars have a high melting point of up to 2617 ℃, allowing them to keep stability at high temperatures. They also possess excellent thermal conductivity, low thermal expansion, and corrosion resistance. They are commonly applied to produce high-temperature components. Shanghai Yuepeng can supply high-precision molybdenum rods and bars with tight tolerances and various specifications. The customized solutions are available according to specific requirements.

Molybdenum Rod/Bar Production Process

• Raw Material: Select high-purity molybdenum powder.
• Powder Metallurgy: Mix with binder and compact into a green billet.
• Sintering: High-temperature sintering to remove the binder and increase density.
• Heat Treatment: Anneal to relieve stress and enhance properties.
• Surface Treatment: Clean and polish the surface.
• Cutting & Customization: Cut or customize according to requirements.

Molybdenum Rod/Bar Surface Finish

Depending on the intended applications, molybdenum rods and bars have three main surface finishes as follows:

• Black: The surface is “as swaged” or “as drawn”, retaining a coating of processing lubricants and oxides.
• Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.
• Ground: The surface is centerless ground to remove all coating and to achieve precise dimensions control.

Molybdenum Rod/Bar Applications

• High-Temperature and Vacuum Furnaces: Due to their high melting point and good stability at high temperatures, molybdenum rods and bars are commonly used in high-temperature furnaces and vacuum furnaces as heating elements, electrodes, and radiation shielding components.
• Semiconductor Industry: Molybdenum rods and bars are used as electrodes, contact materials, and substrates in manufacturing semiconductor devices.
• Optical Coating: Molybdenum rods and bars are used as electrodes and cathodes in optical coating, for the deposition of thin films and etching processes.
• Aerospace: Molybdenum rods and bars are used in the aerospace industry for producing high-temperature engine components, aero-engine nozzles, and other components.
• Welding and Cutting: Molybdenum rods and bars are used in resistance welding, arc welding, and plasma cutting applications.
• Chemical and Metallurgical: Molybdenum rods and bars are used in the chemical and metallurgical industries for reactors, catalysts, electrodes, and heating elements.

Molybdenum Rod/Bar Packaging

The Molybdenum Rod/Bar is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
