Powder spheroidization technology for high melting point materials using plasma melting.
[Particle size 10-70μm] We offer spherical powders of high melting point materials with high packing density and sphericity, produced by high-frequency thermal plasma melting at 10,000℃!
At Niimi Industry, we use the "N-Plasma Melting (high-frequency induction thermal plasma method)" to granulate spherical powders of high melting point materials. High melting point metals such as WC (tungsten carbide) and W (tungsten) are spheroidized into powders with high sphericity and high purity. By achieving a spherical shape, we realize improved flowability, increased packing density, and enhanced surface hardness of the powders. 【Compatible Materials (High Melting Point Materials)】 ■ High melting point metal powders: Tungsten W, cemented carbide WC, Molybdenum Mo, Inconel, Platinum Pt ■ Composite powders: Copper ■ Inorganic powders: SiO2 silica, glass, ZrO2 zirconia 【Features of Niimi Industry's "Powder Spheroidization Treatment"】 - Ultra-high temperatures exceeding 10,000°C and high enthalpy - Generation of large volumes of thermal plasma - Clean plasma generated by non-electrode discharge - Spheroidization of high melting point materials (metals and ceramics) - Provides powders with good flowability due to the ability to achieve a spherical shape - Suitable for metal powders used in 3D printers *For more details, please refer to the technical materials available for download in PDF format or feel free to contact us.
