Molybdenum Wire

Molybdenum Wire

Molybdenum wire is a type of wire made from the chemical element molybdenum. Molybdenum is a silvery-white metal with a high melting point, making it an ideal material for use in high-temperature applications. Molybdenum wire is typically made through a process called drawing, where a molybdenum rod is pulled through a die to create a thin, uniform wire. Molybdenum wire is known for its high strength, corrosion resistance, and ability to withstand high temperatures. It is commonly used in the manufacturing of filaments for lamps, electrical contacts, heating elements, and in the aerospace and defense industries.

Molybdenum Wire Capability

Our molybdenum wire is produced by stretching the Molybdenum rod to various diameters after the rod undergoes the pass rolling and rotary forging to about 3mm. The Advantages of our molybdenum wire are good stability, good tensile strength, high precision cutting, and low elongation. Our factory can provide various molybdenum wires with a diameter of 0.18~3.0mm, we can also provide custom products to your requirements. We offer 2,000 to 3,000 kg of pure molybdenum wire products per month.

Molybdenum Wires Surface

  •   Black Oxide - 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. 

Molybdenum Wire Applications

Molybdenum is an outstanding material that can meet the most exacting requirements of its high melting point, low coefficient of thermal expansion, and high level of thermal conductivity. Heeger Materials provides customized molybdenum and its alloy products.

  • Molybdenum wire is used for profile cutting, H2 furnace, heater rod guide rod hook, mandrel, wire, lead, etc.
  • Molybdenum is used in the manufacture of high-temperature-resistant equipment, such as brackets, guide rods, heating rods in the furnace, etc.
  • Molybdenum wire is mainly used in molybdenum furnaces and electronic tube socket high-temperature hot fields.
