Tungsten Crucible

Tungsten crucible is mainly divided into sintering forming (applied to powder metallurgy technology), stamping, spinning type. The use of tungsten rod turning processing molding (general size is relatively small), welding molding a variety of pure tungsten plate, tungsten sheet and pure tungsten rod through the corresponding process. Tungsten crucible can be used in vacuum inert gas below 2600 degrees. Tungsten has high melting point, high boiling point, good high temperature strength, abrasion resistance and corrosion resistance, large thermal conductivity, small coefficient of thermal expansion and good hardenability. Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.
