Tungsten Crucibles

Tungsten Crucibles (English name: Tungsten Crucibles) is one of the metal tungsten products, mainly divided into sintering 

forming (applied to powder metallurgy technology) stamping forming, spinning type. Using tungsten rods for turning and forming 

(generally small in size),welding and forming various types, using pure tungsten plates and tungsten sheets


It is processed with corresponding processes with pure tungsten rods. Tungsten crucibles can be used in vacuum inert gases 

below 2600 degrees Celsius. Tungsten has a high melting point and boiling point ,good temperature strength, wear and corrosion 

resistance, high thermal conductivity,low coefficient of thermal expansion, and good hardenability.  Tungsten crucibles are widely

 used  in rare earth smelting, quartz glass electronic spraying, crystal growth and other industries.


Physical and chemical properties:


1. Purity: W ≥ 99.95%;


2. Density: ≥ 18.5g/cm3;


3. Application temperature environment: 2400 ℃.


Production process: tungsten powder - sieving - batching - isostatic pressing - rough turning processing - medium frequency 

sintering - fine turning processing - packaging.
