More info

Molybdenum Wire is known for its exceptional high-temperature performance and resistance to corrosion. It finds widespread use as a heating element in high-temperature furnaces and as a wire mesh to support materials. Additionally, it serves as a key component in manufacturing electrodes and heating elements for electric vacuum devices, along with various other applications in environments characterized by elevated temperatures.

Molybdenum Wire Specifications

The molybdenum wire is produced by stretching high-purity molybdenum rods to various diameters, following pass rolling and rotary forging processes. Our wires offer several advantages, including excellent stability, tensile strength, precision cutting, and low elongation. HM offers a wide range of molybdenum wire diameters from 0.18mm to 3.0mm, with customizable options available upon request. Our factory produces 2,000 to 3,000 kg of pure molybdenum wire products every 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. 

  • 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. 

Molybdenum Wire Packing

Molybdenum rods are placed in wooden cases supported with soft materials to ensure that the products thus packed will not shift inside the cases. This packaging method guarantees the integrity of the rods throughout the transportation process.
