Spherical Tungsten (W) Powder

Spherical Tungsten(W) Powder has the characteristics of high purity, ultra-low oxygen, high sphericity, smooth surface, no satellite ball, uniform particle size distribution, excellent flow performance, and high loose density and vibration density.

Tungsten Powder Applications

Tungsten powder is mainly used in the production of weight fillers, radiation shielding fillers, induction accelerators, etc. The thin film surface of its polymer mixture makes it suitable for radiation protection. It is also an ideal heavy metal filler for injection-molding applications due to its large particle size. Tungsten powder is suitable for applications in the metal spray industry.

Tungsten Powder Packaging

Tungsten powder is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
