Tungsten Products
Chemical symbol: W
The density:19.35 g/cm³
The boiling point: 5927 ℃
Atomic number: 74
The melting point: 3410 ℃
Tungsten is a rare metal, and it is widely used in steel, chemical, cemented carbide, electronic, automotive, new energy, medical, aerospace, and other fields due to its high melting point, high hardness, excellent corrosion resistance, and good electrical and thermal conductivity.
Powder
The main raw materials for tungsten products and cemented carbides, and the additives for chemical products such as intelligent glass and thermal insulation coatings; cathode materials for lithium ion battery; catalysts for petrochemical industry, colorants for paints, additives for fireproof fabrics, etc.
It is an important raw material for the production of cemented carbide. It can improve the hardness of cemented carbide, but reduce the transverse fracture strength and relative density of cemented carbide at the same time.
It is used as the main raw material of tungsten products and tungsten alloys and for making tungsten carbide powder and cemented carbide tools.
Intermediate Products
Tungsten Tubes & Tungsten Nozzles
They are used for all kinds of high temperature shielding and heat-resistant materials.
They are used as electrode materials for rare earth metal smelting, arc smelting and so on.
They are used as electrode materials for rare earth metal smelting, arc smelting and so on.
Finished Products
Tungsten Heaters in Semiconductor MOCVD Device
They are used as a component of semiconductor MOCVD system.
It is used as a diffusion barrier to prevent the diffusion of Al or Cu in Si, and has adhesion to the materials in contact with it.
It is used as a filler for through holes (Vias) between metal layers and vertical contact holes (contact), i.e. tungsten plug.
