Advantages:
1. Anti-oxidation treatment to maximize service life.
2. Produced with special process. High bulk density and low porosity resist erosion of molten aluminum and its gas particles.
3. High purity, low ash content graphite material prevents volatile substances, avoids spots, holes on aluminum coated film.
4. Graphite crucible treated by special coating process, resists oxidation and maximizes service lifespan
5. Exact machining of graphite crucibles. Polished mirror surface and exact sizes.
