Brief
This silicon carbide graphite crucible is mainly used in the melting of non-ferrous metals, such as aluminum copper, brass, etc. With the advantages of fast heat conduction, high temperature resistance, good thermal stability and no reaction with melting.
Features
Use high thermal conductivity of graphite and other raw materials, shorten the melting time.
Heat shock resistance: high heat shock resistance, not easy to crack when cold or hot.
High heat resistance: high temperature resistance, can withstand 1200~1650 high temperature.
