Molybdenum is an element that shares many properties with tungsten. Like tungsten, it is very hard and has a very high melting point. Unlike tungsten, it has greater ductility and a lower density. In EDM, the similarities between molybdenum alloys and tungsten alloys result in a great amount of overlapping applications.

Molybdenum Characteristics

  • Properties are similar to those of tungsten and its alloys.
  • Electrodes are available in rods and tubes.
  • Available in rods and tubes.
  • Low carbon arc cast (LCAC) molybdenum is available.
  • LCAC molybdenum is 99.97% pure, with a maximum carbon content of .01%.
