CHEMETAL USA supplies molybdenum rod with diameters ranging from 0.029 ″ to 4.0″ or more. We can cut moly rod into customized lengths based on the diameters of the rod chosen by customers. The rod surface conditions include black, ground and polished. The black surface rod is fabricated by undergoing either the swaging or drawing machine or both. Afterward, a black and thin layer of oxide adheres to the finished rod. The ground surface rod is further processed by passing through the centerless grinding equipment which can remove the black oxide. CHEMETAL USA specializes in the manufacturing of molybdenum rod. We understand that top quality control is crucial to manufacturing products that satisfy our customers. Due to this, we have put a great deal of attention on monitoring every single step starting with the beginning of the forging to the end of the examination.

Molybdenum Rod Properties and Applications

Molybdenum’s high strength and chemical stability make it ideally suitable to work under a high temperature and pressure condition. The vapor pressure of molybdenum is far above the range of pressure a typical vacuum furnace creates. Therefore, molybdenum is typically used to make all-metal hot zones for vacuum furnaces in which the temperature is up to 1500°C.  What’s more, due to molybdenum’s slow erosion rate and high creep resistance in molten glass, there is barely any negative effects to chemical and dimensional stability when molybdenum made electrode immerses in variable glass chemistries. Molybdenum rod is a perfect material used to make thermal conductors, welding electrodes, headpieces for the industries of quartz, stirring bars for smelting, heavy hammers, fasteners, etc.

Properties

  • High Density: 10.3 g/cm³
  • High Melting Point: 2625°C (4760 °F)
  • Low Vapor Pressure
  • High Tensile Strength
  • Low Coefficient of Thermal Expansion
  • Low Electrical Resistivity
  • Good Machinability
  • High Absorption Capacity
  • High Elastic Modulus

Applications

  • Furnace pillars for sapphire crystal furnaces and other vacuum furnaces
  • Furnace heater for sapphire crystal furnaces and other vacuum furnaces
  • Tungsten headpieces for the industries of quartz
  • Stirring bars for glass smelting and rear-earth smelting
  • Tungsten heavy hammers
  • Connecting rods
  • Screws/bolts and other fasteners
  • Furnace support pillars
  • Electrodes for welding electrodes and rare earth metal industry

TZM Rod Properties

High temperature TZM rod is a popular molybdenum-based alloy utilized in the furnace and in heat-treating structural components such as shielding and supporting parts. This is because it has a high creep resistance. What is more, TZM molybdenum rod is extremely suitable to make high temperature and high strength TZM moly forging dies for isothermal forging, non-ferrous and ferrous metals casting and Molybdenum piercing plugs. In addition, TZM alloy is an excellent choice as a weldable and higher recrystallization temperature material used to produce Molybdenum rocket nozzle.

  • Creep Resistance
  • High Tensile Strength
  • Good Machinability
  • High Recrystallization Temperature
  • Corrosion Resistance
  • Good Weldability

Lanthanated Molybdenum Rod Applications

Some rapidly developing industries such as Semiconductor and high temperature industries use a large amount of Lanthanated Molybdenum rod products. Moreover, Lanthanated Molybdenum rod has been used extensively to produce Piercing head in mill due to its wear resistant and dimensional stability and strength under high stress.
