Tungsten Products


Tungsten has the highest melting point (3410°C) and the lowest vapor pressure among all the metals, which makes it the best choice for a variety of high-temperature operating environment. Tungsten products feature high melting point, low thermal expansion, high resistivity, low vapor pressure, good thermal conductivity and high density. They are mainly applied in such industries as electronics, aerospace, chemical and medical industries.


Pure tungsten is mainly used for electrical and electronic equipment. Owing to its fairly high melting point, it is commonly used in aerospace and high-temperature applications, such as electronics, heating and welding. Tungsten, besides, is very hard and very close, which makes it ideal for making heavy metal alloys that can be used on armor, heat sinks and in high-density applications like ballasting, weight balancing, and boats and aircrafts ballasting. Pure tungsten products are broadly utilized for furnace parts, semiconductor substrate components, electron tube, emitting cathode for electron beam evaporation, cathode and anode for ion implantation, sintered capacitor of tube / vessel, x-ray diagnosis, crucible, heating elements, x-ray radiation shielding, sputtering target and electrode.
