Material Property

Tungsten ,melting point 3420ºC, has an excellent high temperature strength and good corrosion resistance to the molten alkali metals and steam. Its high thermal stability makes it still works normally under the environment of high temperature.

Tungsten has good strength, high hardness and high temperature performance, low resistivity, low expansion coefficient, low electron work function, etc, is the most widely used high temperature resistant metal materials.

After doped with 65~70ppm potassium, the tungsten rod form an elongated stacked microstructure inside which improved the material to a better high-temperature properties such as better creep resistance and dimensional stability.


In recent years ,with the widely application of the LED lighting, the demand of the sapphire substrate materials expands rapidly. The sapphire growing temperature is above 2200 ℃, the process needs the long time stability of thermal field. Tungsten has been widely used in the furnace for its low pollution and high melting point.

Use of tungsten and molybdenum materials preparation of cage type heating element can very good satisfy long sapphire crystal furnace to the stability of the temperature and thermal field of the environmental requirements.
