SiC Graphite Crucible for Molten Copper Aluminum Gold Silver Casting Long Service Time

1. About materials:

    What we used is high purity, three high ,fine grain graphite material, (moulded through big press machine, the graphite will be pressed more compact,lower porosity rate,so the oxidation resistance will be better). Our crucible moulds are made of quality graphite, with good thermal conductivity, which can well shorten the melting time and save energy, can withstand 2000 degree Celsius, resistant to corrosion and compression, flexible and durable, not easy to break or deform, can serve you for long time.

2. About the features of graphite crucible:

1). Graphite crucible has the feature of good heat stability, can resistance to thermal shock 

2). Corrosion resistance: the feature of good acid and alkali resistant will keep the using performance.
3). Graphite crucible has good of thermal conductivity, can save melting time and energy.
4). Very Low ash can keep the precious metal clean , avoid to be polluted.
