EDM Molybdenum Wire

About EDM Molybdenum Wire

Thin molybdenum wire is a versatile form of molybdenum metal used in various applications due to its unique properties. Molybdenum is a highly refractory metal, meaning it has a very high melting point (2623 C or 4753 F). It also boasts high strength at elevated temperatures, good electrical and thermal conductivity, and good resistance to corrosion. However, thin molybdenum wire is relatively brittle and can be easily broken if bent sharply.

Here are some characteristics of thin molybdenum wire:

• Diameter: Thin molybdenum wire typically ranges in diameter from 10 microns (0.0004 inches) to 500 microns (0.020 inches).
• Material: Molybdenum (Mo) with a minimum purity of over 99.95%
• Color: Shiny gray
• Properties: High melting point, good electrical and thermal conductivity, good corrosion resistance, but brittle.

Applications of Thin Molybdenum Wire:

• Electronic applications:

  
  

  • Cathodes for electron emission.
  • Heater elements in high-temperature furnaces due to its ability to withstand high temperatures without sagging or melting.
  • Electrical leads and wires in vacuum environments due to its high melting point and good electrical conductivity.
  • Aerospace applications:
    • Filaments in ion implantation systems used to dope semiconductors.
  • High-temperature heating elements in furnaces.
  • Other applications:
    • Support structures for high-temperature components.
    • Sputtering targets for depositing thin molybdenum films
  • • Mandrels for filament winding
    • Molybdenum wire can also be used in dentistry for orthodontic purposes.

  When choosing thin molybdenum wire, it's important to consider the diameter, material properties, and intended application. Suppliers can provide spools of thin molybdenum wire in various lengths and diameters

  • Grids in electron tubes for controlling electron flow.
