Vibration Molding Graphite Block & Round
VG series fine grain graphite has an exceptionally homogeneous structure, almost isotropic properties and low ash content. It can be manufactured in large sizes. Further processing, for example impregnation is possible. VG series graphite is widely applied in metallurgical, machinery, electronics, chemical, powder metallurgical.
