Features of Tungsten Crucible
The crucible can be used in vacuum inert gas environment under the temperature of 2600℃;
It has a very high purity of 99.95% and high density over 18.7g/cm3;
It has high melting and boiling points, high temperature strength, high abrasion resistance as well as high corrosion resistance;
Tungsten crucible also possesses good thermal conductivity, good hardenability and low thermal expansion coefficient;
We produce tungsten crucibles with accurate size, clean bright internal and external wall.
