99.95% Pure Tungsten Crucible

tungsten crucible

We are professional maker of standard and special small tungsten crucible, they are mainly produced by grinding and drilling from pure tungsten rods or plates.  

Since the melting point of tungsten has reached 3410°C, and it has high temperature strength, abrasion resistance and corrosion resistance, large thermal conductivity, small thermal expansion coefficient and good hardenability.  So the tungsten crucible is widely applied in the industry furnace, such as sapphire growth furnace, quartz glass melting furnace and rare earth smelting furnace.
