For filament for lighting, electrode, high-temperature furnace parts, etc,
Tungsten wire is used as filaments for lighting, electron tubes, electrodes, high-temperature furnace parts, probe pins, by making the most of its characteristics: the highest melting point among metals. Customers can choose wires from a variety of wire diameters, materials and finishing method for various applications. We also offer the world’s highest level high-purity tungsten wire by our integrated production and strictly controlled raw material and processes.
|Features excellent high-temperature deformation resistance, blackening resistance, shocking resistance, less impurity gas, and long life.
|Compared with conventional materials, the recrystallization temperature is higher (by 50° to 200°C), dope hole is smaller, crystal structure after recrystallization is 3 to 4 times longer, and non-sagging performance is greatly improved.
|World’s No.1 grade filament material. It contains less impurity gas, excels in high temperature deformation resistance and corrosion resistance against evaporated metals including Al, Ni, Cr. Moreover, it has a long life.
|Long lifetime tungsten material that facilitates emission of thermo-electrons and prevents grain growth and integranular fracture at thermionic emission temperature. We respond to coil processing, tip processing, and assembly processing upon your request.
|The most common pure tungsten material with good workability, excellent corrosion resistance, and less impurity gas contained.
|Dramatically reduces discharge consumption resistance by finely dispersing crystal grains.
|World’s highest grade high-purity tungsten material.
