1. Good thermal stability, considering sudden heat and cold working condition, we apply special raw materials.
2. Impact resistance: Graphite crucible can withstand strong heat impact, therefore your can use it for any workmanship process.
3. Good thermal conductivity: Due to its high thermal conductivity, you can shorten melting time, saving energy.
4. Ash content is less than 300pp, melting metal can not be polluted during melting process.
