Advanced Graphite Materials Solutions For Industry
GRAFSTAR™ advanced graphite is an ideal choice for customers across multiple industries with demanding applications requiring high strength, low thermal expansion, and superior conductivity. For over 100 years, Advanced Graphite Materials has been continuously redefining limits with ongoing testing, grade formulation, machining, and purification to develop innovative graphite material solutions for customers in over 65 countries.
Advanced Graphite Materials sets the industry standard in graphite, machining diameters up to 73” and larger jointed diameters upon request. We provide the expertise and solutions to keep you ahead of the competition – recommending design changes to reduce machining costs and handling any CAD/Cam system in use, eliminating barriers in language and measurement systems.
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.
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.
