Pyrolytic Graphite & Machined Components

Pyrolytic graphite parts
  • High Purity
  • High Density
  • High Strength
  • High Hardness
  • Virtually Zero Porosity

GMI's sister company, Advanced Carbon Technologies, manufactures pyrolytic graphite using a high temperature Chemical Vapor Deposition (CVD) process. The resulting material offers many unique properties including extremely high purity, density, strength and hardness along with virtually zero porosity.

The pyrolytic graphite material is grown onto a substrate giving it a layered composition which has different properties in different planes. In the C plane (across its layers) it has low thermal conductivity, acting as an insulator. In the A-B plane (with the layers) it has very high thermal conductivity, acting as an excellent conductor.

GMI can provide pyrolytic graphite as a raw material in plates, free standing shapes or as an impermeable coating on graphite or other substrates. It can also be machined to your specifications in one of our state-of-the-art machining facilities.
