Specialty Graphite Review

Specialty or custom graphite materials and shapes are available within industry. Specialty Graphite may be fine grain extruded graphite principally used for machining and fabrication or in pursuit of complex engineering specifications.

Specialty Graphite is molded and isotropic graphite which is would be supplied in block, round and rod. There are at least four grain sizes. The grain sizes determine grades, which are labeled differently by various manufacturers.

Graphite densities range from just under 99lb per cubic foot to slightly more than 112 lbs. per cubic foot.

Specialty graphite materials and shapes applications:

Sintering
Ceramics
Armor plating
Dressing Rolls
Extrusion
Blow Molding
Plastic Injection Molding
Reinforced Fiber Materials
Glass Manufacturing
Materials Impregnation

Typical engineering specifications include:

Density
Porosity
Hardness
Flexural Strength
Compressive strength
Coefficient of thermal expansion
Electrical resistivity
Thermal Conductivity
Grain Size Average
Delivered geometry or shape.

Graphite Material Characteristics

High Thermal shock resistance
High mechanical strength and impact resistance
Low friction or sliding properties
Low wetability with fewer tendencies to stick to selective materials, such as glass.
Corrosion resistant
High thermal stability
Thermal conductivity properties can be changed or modified at manufacturing
Good porosity characteristics
