High density graphite is ideal for vacuum heating elements. The graphite elements are highly inert and the material actually increases in strength as it becomes hotter. Another feature of the material is that it has a low expansion coefficient and is resistant to degrading due to constant heat cycling therefore, it has a good lifespan in this respect and a relatively fast ramp rate.
The elements are made from blocks of high purity graphite and with the correct material selection the graphite can be machined into detailed forms for one off or low volume batches. If you can not find your requirement in the stock items below or in the gallery then please contact us to discuss you requirement further. The designs can be of a 3D nature to produce a tubular heater or flat as required. Alternatively, we can design elements or work from existing drawings.
Thermic Edge can provide Silicon Carbide coated elements or Titanium Carbide coating to further enhance these element in terms of purity and using graphite in air.
