Tungsten has the characteristics of high melting point, high strength and hardness, good high temperature performance, low resistivity, small expansion coefficient, and small electronic work.
Tungsten crucible is one of the metal tungsten products. It is mainly used as high temperature furnace container. It can be used in vacuum or inert gas below 2600 ℃.
According to customers' requirements, we can provide conventional density (≤ 18.3g/cm3) and high density crucible (≥ 18.5g / cm3).
The inner surface is smooth and smooth ≤ 1.6, and it can produce zero pollution even at high temperature.
After special process treatment, the deformation resistance of the bottom of the crucible is significantly improved.
Tungsten crucible is a kind of crucible made of metal tungsten. It has the characteristics of high melting point, high strength and hardness, good high temperature performance, low resistivity, small expansion coefficient and low electron work. It is an important part of sapphire long crystal furnace.
Tungsten crucible products have been used in more than 100 sapphire crystal factories, quartz glass factories, high temperature heat treatment plants and rare earth smelting plants in China for many years,
