Species Of Molybdenum Wire

2024-01-05 18:00:06

   Molybdenum content :>= 99.95%

   Type: Black molybdenum wire, white molybdenum wire, spray wire, high temperature molybdenum wire, wire cut wire.

  Black molybdenum wire

  Use: high temperature, high strength, wear resistance, good solderability, strong creep resistance, good ductility and long service life.

  It is widely used in wire drawing die, casting mold, gate, high temperature stirring rod, high temperature cushion plate, high temperature structure piece, support part, electronic tube shelf, incandescent lamp hook, PL line, vacuum or protective atmosphere heating material support rod, drawing line, grid and so on.

White molybdenum filament

   Clean molybdenum wire is electrolytic polishing. The surface should be clean, smooth, bright and uniform in size. Which is Mainly used for spiral filament, leading, supporting and other components mandrel.

  The use of molybdenum is not big, the vacuum tube is mainly used to make the cathode, anode, the light bulb in the brackets of tungsten, etc.In 1927, ultra pure metal molybdenum, the purity is 99.999%, pull the filament, besides the wire, the metal molybdenum wire EDM also used .In recent years, the numerical control electric fire flower is made in China, it is cut with conductive metal. Molybdenum wire , inert gas protection,and tungsten wire can be made into high temperature thermocouples to measure the high temperature at 1200-2000 degrees Celsius.
