    Tungsten Heating Elements
  • Description of Tungsten Heating Elements:

    Tungsten Heating Element (Tungsten heater) is made from Tungsten wire or other tungsten products, which has high melting point and excellent corrosion resistance. It is mainly used as heating elements in surface vacuum coating process such as aluminum spraying, chrome-plated, mirror making, ceramic coating and plastics coating, etc.
    Tungsten Heating Element (Tungsten heater) can be produced into single or multi wires form according to customers& #39; drawings. Pure tungsten wire and doped tungsten wire are both available.
    Tungsten Heating Element (Tungsten heater) also can be made from tungsten strip and tungsten rods. We can provide Tungsten Heating Element (Tungsten heater) according to your drawings.
    Purity: W >99.95%
    Density: >19.10g/cc
    Application temperature environment: <2300°C

    Application of Tungsten Heating Elements:

    Tungsten heating elements can be expected, under proper conditions, to maintain temperatures up to approximately 2300°C. They are widely applied in high-temperature resistance furnace, sapphire growth furnace.

    Properties of Tungsten Heating Element:

    1. High mechanical and thermal stability
    2. Excellent uniformity
    3. Low creep deformation
    4. Long life times
