 Graphite material is widely used for crucibles, which provide a non-reactive vessel that will survive the high temperatures needed for metal melting and processing. Graphite crucible is used for melting non-ferrous and metals such as gold, silver, aluminum or brass, ect.
 
There are different types of crucibles. We could manufacture the graphite crucible according to your drawing. Or if you have requirement about the capacity, dimension, we could offer suggestion and produce based on your demands.
Our company is the professional manufacturer and exporter for carbon and graphite  products. our company was established at 2000.Our factory is located in Beijing city.and 50 kilometers from Beijing airport.
We mainly produse graphite rod, graphite block, graphi.te crucible,graphite mould, graphite bearing,graphite felt,carbon fiber cloth,etc.
make it according to drawing and specifications.
for the graphite,We have mold graphite,isostatic graphite,extruded graphite,vibration graphite. bulk density from 1.6g/cm3 to 1.91g/cm3.
