High Strength

Unlike most materials, the mechanical strength of graphite increases with temperature. Graphite is twice as strong at 2500°C as it is at room temperature.

Low Thermal Expansion

Matching the coefficient of thermal expansion between materials is important for many applications. Graphite has an extremely low coefficient of thermal expansion. It can be tailored to the application by carefully selecting the formulation.

Superior Conductivity

Graphite has a thermal conductivity of above 100 W/mK, very similar to many metals. Carbon material does not have the highly ordered crystalline structure of graphite and has a very low thermal conductivity.
