Medium-coarse grain graphite is a carbon-based material characterized by its high-purity structure (≥99.99% carbon) and uniform particle distribution (0.8/2/4 mm), offering excellent thermal stability, chemical inertness, and self-lubricating properties. It exhibits low thermal expansion, high electrical/thermal conductivity, and resistance to oxidation, making it ideal for extreme environments.Demensions：400X400X1800-2100mm，500X500X2100mm，650X500X2100-2400mm,850X500X2100-2500mm,950X500X2300-2600mm,and so on.
