Molybdenum wire is able to resist high temperature with lower elongation, which enables it to be used in high pressure and high temperature applications.
Compared to tungsten, it has a lower density, and higher weight to strength ratio. In some certain areas, molybdenum is instead of tungsten.
Apart from it, molybdenum wire is not very active in chemical. It can resist air and water under normal temperature. Only when the temperature comes to 400℃, it begins to oxide.
Molybdenum wire is used as mesh reflector in antennas, support, mandrels for coils and heaters, lead for discharge lamp and glass sealing parts.
