Description

Tungsten (W) Nanopowder / Nanoparticles

Purity: ≥99.95% (Metal Basis) | Particle Size: ~750 nm | Shape: Irregular | True Density: 19.3 g/cm³

Tungsten nanoparticles exhibit exceptional thermal, mechanical, and electronic properties. With extremely high melting and boiling points, along with excellent conductivity and hardness, tungsten nanopowder is ideal for applications that demand durability under extreme temperatures and mechanical stress. Due to their reactivity and flammability, tungsten nanoparticles require careful handling and vacuum-sealed storage.
