Graphite Block

Molded Graphite (M Series) Feature:

1. High density / Fine grain size / High purity / High strength / Low specific resistance / Ease of precise machining 2. Excellent thermal shock resistance to high temperature and oxidation / Good anticorrosion .

Application:

Semiconductor (Monocrystalline Silicon) / Vacuum furnace / Continuous casting / Sealing products / Space & medical industry / Forge moulds EDM. Heaters / Heat shields /Electronic tube anodes / Melting and sinteringmoulds for Pottery & Electronic Products & Cemented Carbide &  Diamond &  Aluminium & Copper & Other metals/ Etc.
