Graphite

Graphite is ideally suited for high temperature applications in vacuum or inert gas atmosphere thanks to its chemical, physical and thermal properties.

A broad range of graphite material grades are available at GTD; each grade having its own unique properties, which are tailored to suit your specific requirements. As graphite is available in large blocks, virtually any kind of form or design may be realised.
