About This Product

■Product overview

Used for lighting, electrodes, high temperature furnace parts, etc. It has the highest melting point of all metals, and is used for lighting filaments, electron tubes, electrodes, high-temperature furnace parts, probe pins, etc. We offer a variety of wire diameters, materials, and finishes to suit your application. In addition, by taking advantage of our integrated production process starting from raw materials, we provide the world's highest level of high-purity tungsten wire through strict control of raw materials and processes.

■Applications

Filaments for halogen lamps, electrodes for projector lamps, etc.

■Variety selection guide

・AW: Excellent high-temperature deformation resistance, blackening resistance, and earthquake resistance, and contains less impurity gas and has a long life. ・AX: Compared to conventional materials, the recrystallization temperature is 50 to 200°C higher, the dope pores are smaller, and the length of the crystal structure after recrystallization is 3 to 4 times longer, greatly improving non-sag properties. did. ・EX: Contains little impurity gas, has excellent high-temperature deformation resistance and corrosion resistance against deposited metals such as Al, Ni, and Cr, has a long life, and is the world's first-class filament material. ・DW: Long-life tungsten that facilitates thermionic generation and prevents crystal grain coarsening and grain boundary cracking at the thermionic emission temperature. Upon request, we can also handle coil processing, tip processing, and assembly processing. ・CY (PFW): The most common pure tungsten material. It has good processability, excellent corrosion resistance, and contains little impurity gas. ・EP, KT: By finely dispersing crystal grains, discharge resistance and wear and tear can be significantly reduced. ・4N-W: Tungsten with reduced impurities and increased purity to over 99.99%. ・5N-W: The world's highest level of high-purity tungsten with impurities reduced to the absolute minimum with a purity of over 99.999%. It is used in various discharge lamp electrodes and cutting-edge technology fields where trace amounts of impurities are averse.
