To ensure the electromagnetic characteristics and processing quality and efficiency of cutting magnetic components, the properties of nonmagnetic and good wear residence of Forming die and cutting tool are the major factors.

As an important solid lubricating material, tungsten disulfide has a wide range of applications in aerospace, machining, new energy vehicles, medical, electronics, digital and other fields due to its excellent tribological properties. However, the carrying capacity of pure WS2 film is low, and it is easy to absorb moisture and oxidize in humid air, which seriously shortens its service life.

The applications of nanocrystalline tungsten oxide (WO₃) include electrochromic, photochromic, gasochromic and sonochromic devices, as a photocatalyst for water splitting and purification, for photoelectrochemical decomposition of water, in heterogeneous catalysts. With the excellent gas sensitivity, another important application is gas sensors.
