best price high quality and purity temperature superfine spraying tungsten crucible for melting
Tungsten crucible includes sinter molding, press forming, spin forming, turning forming from tungsten rod, weld forming, etc.The sintered tungsten crucible is made from tungsten powder by pressing and sintering,suitable for many specifications.Other tungsten crucible is made from pure tungsten plate, tungsten sheet or tungsten rod by the corresponding processing, generally suitable for the requirements of thin thickness and small size. The tungsten crucible can be used in vacuum inert gas below 2600 °C. Tungsten has high melting & boiling point, good high-temperature strength, wear resistance and corrosion resistance, big Thermal thermal conductivity, low coefficient of thermal expansion, good hardenability. Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.
