Tungsten Crucible

Tungsten Crucible




Manufacturing process of tungsten crucible:
We have special production in

tungsten crucible

manufacture. The process includes isostatic pressing, mechanical processing, sintering, mechanical processing, detection check and other further processing.

Tungsten crucible applications:
Tungsten crucible is widely used to the sapphire growth furnaces, quartz glass melting furnace, crystal furnace, induction furnace, sintering metal mold of high melting point, electronic beam coating, and rare earth smelting furnace.

Properties of tungsten crucible:
Our tungsten crucible has advantages of high purity, high density, low resistivity, high strength, low thermal expansion, erosion resistance. In addition, the surface of our tungsten crucible polished, therefore, there is no crack and the inside and outside wall is smooth.
