Product Description

graphite crucible for jewerly tool gold melting

graphite crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.

Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals.
Advantage:
1. High density
2. Good thermal stability and distortion resistance at high temperature.
3. High mechanical strength at high temperature.

4. Excellent thermal shock resistance.
5. High thermal conductivity.
6. Perfect oxidation resistance.
7. Excellent corrosion resistance against chemicals at high temperature.
8. High abrasion resistance.

9. Long service life.
