MSE PRO™ 3N5 (99.95%) Tungsten (W) Wire Evaporation Materials, 10m Length

Tungsten (W) is a rare metal that has the highest melting point and boiling point of all known elements. It occurs in many alloys, which have numerous applications, including incandescent light bulb filaments, X-ray tubes, electrodes in gas tungsten arc welding, superalloys, and radiation shielding. Tungsten's hardness and high density make it suitable for military applications in penetrating projectiles. Tungsten compounds are often used as industrial catalysts. Pure Tungsten is evaporated in vacuum to make nano powder or nanowires. It is also evaporated in different atmospheres to make different compound thin films.
