Product Description

Product Description

 

Large Capacity Graphite Crucible for Nonferrous Metals Melting and Casting 

graphite crucible is used for gold, silver and other jewelry casting and recasting.Raw material characteristics: high purity, high density, good thermal resistance, ablation resistance, erosion resistance, oxidation resistance and thermal shock resistance.

The graphite has the following characteristics:

1. Good electric conductivity and high thermal conductivity
2. Low thermal expansion and high resistance to thermal shock.
3. The strength increases at high temperautre, and it can withstand over 3000 degrees.
4. Stable chemical property and hard to react
5. Self lubrication
6. Easy to process
