This tungsten (W) nanopowder is a black, spherical metal powder with a purity of 99.955+% on a metal basis and an average particle size of 65 nm. It suits researchers and manufacturers who need fine tungsten particles for electronic, thermal and structural work.
The particles provide a specific surface area of 17 m2/g, with a true density of 19,3 g/cm3 and a bulk density of 4,1 g/cm3. Elemental analysis shows W at ≥ 99.95, with K ≤ 0.008, Mo ≤ 0.003, Fe ≤ 0.002 and other elements ≤ 0.001.
Tungsten combines good electronic and thermal behaviour with outstanding mechanical strength, which makes it a useful material for electrodes, sensors, heat-resistant coatings, heat sinks and high-performance alloys. The powder is offered in 25 g and 100 g packs.

Tungsten nanoparticles are highly reactive and flammable, so handle them carefully and avoid rapid movement and vibration. Keep the powder away from sunlight, heat, moisture and impacts, and avoid air contact. To limit particle coagulation, store it sealed under vacuum in a cool, dry place. Consult the MSDS before use.
