Tungsten Heating Elements
Tungsten Heating Element (Tungsten heater) is made from Tungsten wire or other tungsten products with a high melting point and excellent corrosion resistance. It is mainly used as heating elements in the surface vacuum coating process, such as aluminum spraying, chrome-plated, mirror making, ceramic coating, and plastics coating.
Tungsten Heating Element (Tungsten heater) can be produced into single or multi wires form according to customers' 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) per your drawings.
Purity: W >99.95%
Density: >19.10g/cc
Application temperature environment: <2300°C
Tungsten Heating Elements Application
Under proper conditions, Tungsten heating elements can be expected to maintain temperatures up to 2300°C. They are widely applied in high-temperature resistance furnaces and sapphire growth furnaces.
