Classified by particle size, tungsten powder can be divided into Tungsten Ultra-fine Powder / Nano Powder, Tungsten Fine Powder/ Micro Powder, and Tungsten Coarse Powder (refer to the Tungsten Powder Grades Above).
Here’s an overview of different types of tungsten powder:
Tungsten powder has extensive application in producing weight fillers, radiation shielding fillers, and induction accelerators.
The thin film surface of its polymer mixture is exceptionally well-suited for radiation protection. Its large particle size makes it an ideal heavy metal filler for injection-molding applications. The distinctive shape and resulting high flowability of the particles make it well-suited for applications in the metal spray industry.
Additionally, Tungsten powder plays a crucial role in producing Tungsten Carbide powder, contributing to the preparation of cemented carbide tools for turning, milling, drilling, and molds, among other applications.
