Moulded Graphite
Medium to Course grain graphites (Max Grain size 3.0mm) where surface finish is not so important, but cost per unit is a critical factor.

Extruded Graphite
Medium grain graphites (Max Grain size 0.8mm) where strength and surface finish are not so important, and cost per unit is a key factor.

Isotropic Graphite
Fine to ultra fine grain with high strength and excellent surface finishes, where component life and application specific graphites are used.
