High Thermal Conductive Carbon Graphite Block For Heat Exchanger
Graphite block is made from the domestic petroleum
coke and widely used in the Tooling (EDM), Mould making (EDM), and General Manufacturing industries. Our blocks are used for different construction applications and these are available in various specifications and sizes to the clients. The graphite block include molded, extruded, vibrated and isostatic. Our main and most preponderant graphite plate is vibratory compaction.
Our products own the following characteristics:
- Low electric resistance,
- Good electric and thermal conductivity,
- High oxidation resistance,
- Greater resistance to thermal and mechanical shock,
- High mechanical strength,
- High machining accuracy and so on.
