Engineering Graphite Materials

Graphite is a crystalline form of the Native Element Carbon and is the most thermodynamically stable form of Carbon at standard temperatures and pressures.

Having properties of both metals and non-metals makes Graphite a unique material. It is flexible but not elastic, has high thermal and electrical conductivity, and is highly refractory and chemically inert.

We provide Engineering Graphite Materials in numerous grade groups and used in a variety of industrial applications where each grade group has unique physical and intrinsic mechanical properties that can be harnessed for specific applications.

Typical grades available are intended for Electrical Discharge Machining (EDM), Industrial and Semiconductor applications.
