Tungsten Crucible

High-performance Tungsten Crucible

Choosing a high-performance crucible is crucial in fields such as high-temperature metallurgy, vacuum coating, and single crystal growth. Our carefully crafted tungsten crucible, with its outstanding characteristics, has become an ideal choice for many scientific research and production fields. If you are looking for high-temperature resistant and high-purity crucibles, tungsten crucibles will be your best choice.

Tungsten crucible is made of high-purity tungsten material and has extremely excellent high-temperature resistance. Its melting point is as high as 3410 ℃, which can withstand various harsh high-temperature experiments and production environments. At the same time, tungsten crucibles also have excellent corrosion resistance and oxidation resistance, and can work stably even in high temperature or highly corrosive media, ensuring the smooth progress of experiments and production.

Tungsten Crucibles Applications:

Vacuum smelting: As a key component of vacuum smelting equipment, tungsten crucibles perform well in high vacuum and high temperature environments, ensuring the purity of metal materials.

Metal melting: used for smelting of various metal materials, especially metals with higher melting points, such as molybdenum, tantalum, niobium, etc.
