Spherical Tungsten Powder
Product Spherical Tungsten Powder (W Powder)
Part Number MEP74-2
CAS Number 7440-33-7

Tungsten has excellent heat resistance and radiation shielding performance. Radio frequency (RF) plasma spheroidized tungsten powder has the characteristics of high sphericity, good fluidity, high purity, high bulk density, full density inside the particle, no hollow powder, and so on. It is widely used in national defense, military industry, medical equipment and other fields.

TRM provides Spherical Tungsten Powder, Nano Tungsten Powder and Micro Tungsten powder. Please contact us for more details.
