Molybdenum Wire

Molybdenum Wire is forged and drawn from high-purity molybdenum rods, available in various types including white molybdenum wire, black molybdenum wire, molybdenum spray wire, and EDM molybdenum wire. They possess excellent thermal conductivity, low thermal expansion, and corrosion resistance. They are commonly applied as high-temperature furnace heating components. Shanghai Yuepeng can supply high-precision molybdenum and molybdenum alloy wires with tight tolerances and various specifications. The customized diameters, lengths, wire types, and surface finishes are available according to specific requirements.

Molybdenum Wire 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 Wire Surface Finish

Depending on the intended applications, molybdenum wire has 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 Wire Applications

• Electronics Industry: Molybdenum wire is commonly used in the manufacture of electronic components such as electronic tubes, semiconductor devices, and vacuum diodes.
• Optical Field: Molybdenum wire has good optical properties and thermal stability, and can also be used to manufacture optical components.
• Aerospace: Molybdenum wire can be used to manufacture aerospace components.
• EDM: Molybdenum wires are used as electrode wires in EDM machines, capable of cutting all kinds of steel and carbide.
• Spary Wire: Molybdenum Wire undergoes special surface treatment and structural optimization, forming molybdenum spray wire. Molybdenum Spary Wire can be applied in plasma spraying, arc spraying, flame spraying, HVOF spraying, etc.

Molybdenum Wire Packaging

The Molybdenum Wire 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.
