• The majority of people I am familiar with, all our engineers and developers, are constantly working on fixing the world.
  • Has The World Changed?
    Has The World Changed?
    “No, I do not believe the world has changed that much, more like it is ever changing. Growing. Evolving. Certainly, from an engineer’s perspective, technology has changed, and I truly believe that whatever people do and whatever people come up with is just a natural process of growing as a society."

The Uses for the Tungsten Wire

The Tungsten Wire is made from a rare metal called ‘Tungsten’ or Wolfram. It is a hard and rare metal to find on Earth and is usually found naturally and almost exclusively in chemical compounds. The most remarkable attribute that tungsten has is that it is robust and has the highest melting point of all metals in the periodic table and the highest tensile strength.

It’s high density is 20 times more than that of water, and can be comparable to Gold or Uranium, which makes it great for high absorption capacities of radioactive radiation and X-Rays.

The many uses of Tungsten Wire include:

  • Coiled Incandescent Lamp Filaments – great conductor of heat
  • Cathode and Support Structures for Power Tubes
  • Aerospace Materials – high conductivity of heat makes it suitable for high heat temperatures.
  • Heating Elements for High Temperature Furnaces
  • Evaporation Sources in Metallizing Processes
  • Medical Devices – as they need to contain the amount of heat being used.
  • LEEP and LEED Electrodes
  • Corona Generation
  • Vacuum Heating Elements
  • Filaments
  • Thermionic Emitters

How is Tungsten Wire Made?

The making of Tungsten wire is a very complex process, as it should be kept tightly controlled when making the wire, to ensure that the proper chemical and physical properties are in check:

  • The first part of the process is Pressing:

the first part of the process is to sift and mix the tungsten powder and then put it into a steel molder.

  • The second part is Presintering:

the molded Tungsten is placed into a refractory metal boat, then loaded into a furnace with a hydrogen atmosphere.

  • Thirdly is the Full Sintering:

the Tungsten is then loaded into a special water-cooled treating bottle. Electric currents will pass through to further densify the Tungsten.

  • Swaging:

placed into a Swager (a machine that reduces the diameter, by hitting it repeatedly.

  • Drawing:

drawn to be fine (0.005 inches) so that it can be used for production.
