Tungsten metal has high melting point and boiling point, excellent high temperature strength, abrasion and corrosion resistance, large thermal conductivity, low coefficient of thermal expansion, good hardenability.
Tungsten crucible is one of the tungsten products. Tungsten crucible can be mainly divided into sintered tungsten crucible, stamping tungsten crucible, spinning tungsten crucible, turning processing tungsten crucible by using the molybdenum rod, welding tungsten crucible and other tungsten crucibles. Tungsten crucible is made of tungsten plate and pure tungsten bar by using corresponding processing technics. Tungsten crucible can be used in vacuum and inert gas under the temperature of 2600℃. Among these kinds of tungsten crucibles, stamping tungsten crucible is greatly used with cheap price. One of the weak point of stamping tungsten crucible is that the thickness of stamping tungsten crucible is very thin affected by the processing technics, which is not conducive to long-term use. For welding tungsten crucible, it not only has cheap price, but also has life service life. So welding tungsten crucible is favored by many users. Tungsten crucible is also the first choice of purchasing.
As for tungsten crucible applications, tungsten crucible can be widely used in rare earth smelting, vacuum sintering, quartz glass, electronic spraying, laser crystal growth and other industries.
Tungsten crucible is an important component of rare earth smelting. So the performance and service life of tungsten crucible are very important. Compared with other kinds of crucibles, tungsten crucible has such advantages as less pollution of smelting metal, long service life and others. Therefore, tungsten crucible is commonly applied in the rare earth industry. Tungsten crucible is an important achievement for the development and application of tungsten deep processing products.
Tungsten and molybdenum manufacturer-Zhengzhou Sanhui Co., Ltd has been concentrating on tungsten metal and other refractory metals production for over 24 years. We provide products for buyers with our wisdom and concentration.
