Filamentary Tungsten Dissipates For Industrial Applications

Filamentary Tungsten Dissipates For Industrial
Applications

• Filamentary Tungsten Dispensers (also sometimes
  referred to as filamentary tubing or filamentary
  anode) are used for the manufacture of the final
  layer of anodized aluminum forging.

• Filamentary Tungsten Dispensers Cathodes (also
  sometimes referred to as filamentary tubing or
  filamentary anode) are used for the manufacture
  of the final layer of anodized aluminum forging.
  As in all manufacturing processes, the ability to
  create the proper anodized product with high
  quality and consistent color requires the use of
  high quality materials. In this case, the
  material to be used is the high quality
  filamentary tungsten cathode (herein referred to
  as a Cathode) and the specific anodizing method
  is generally a non-contact one utilizing a solute
  in the discharge mechanism. The common cathode
  used is tungsten filamentary which is typically
  made from a solid alloy or iron.

• As mentioned above, this specific metal
  fabrication process requires anodized deposits to
  be formed on the cathode in order to achieve a
  finished product with a color matching the
  surrounding metal. Additionally, it is critical
  that the anodizing effect is consistent and last
  through multiple passes with only very minute
  discontinuities in between. The entire
  fabrication cycle is therefore designed to match
  the entire color spectrum from the raw titanium
  to the final product.

• Filamentary Tungsten Copper cathodes are
  typically made by one or more companies. The
  cathode is often produced in bulk to be used in
  mass production methods for high volume products.
  OEMs (Original Equipment Manufacturer) must
  typically certify that their cathodes are
  specifically designed and produced for their
  applications. This certification is typically
  provided to assist customers in making their
  purchasing decisions.

• A common variation among filamentary cathode
  manufacturers includes the addition of nickel to
  improve corrosion resistance. Typically, nickel
  has a cobalt ion and is added in small amounts.
  This is typically done in favor of improving
  performance at a lower cost. Other features to
  note include the incorporation of a thin metallic
  film on the cathode surface. This provides
  additional protection against moisture and
  corrosion.

• Filamentary Tungsten Dissipates typically comes
  in standard sizes. Some manufacturers will even
  custom make them to fit certain applications. The
  anodizing process is achieved with a fine mist of
  aluminum oxide. The anodizing process occurs
  quickly after the cathodes are formed. The
  anodized coating is then allowed to cure for
  several hours before being applied to the metal.

• It should be noted that Filament Laser Diode
  Spacers are used in applications where high
  strength, durability, and excellent electrical
  characteristics are key factors. The anodized
  coating thickness will affect both the strength
  and durability of the cathode. Companies that
  produce these products are aware of this and have
  designed the cathode package specifically for
  their application. The coating thicknesses can
  range in thickness from a few micrometers to
  several millimeters. There is a wide price range
  for these cathodes.
