Tungsten Powder Applications

Tungsten powder is mainly used in the production of weight fillers, radiation shielding fillers, and 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.
