3D Printing Spherical Tungsten Powder 5-25µm


Product Features


Classification:Metal Powders

Keywords: tantalum powder, tungsten powder


Product details

Stardust company provide spherical tungsten powder with high purity hypoxia, high sphericity, smooth surface, no satellite, uniform particle size distribution, excellent flow performance, and high loose density and vibrational density. With its excellent biocompatibility, tantalum implants formed by 3D printing have the closest elastic modulus to human cartilage tissue and are the most ideal orthopedic implants. Spherical tantalum powder is suitable for laser/electron beam augmentation, hot isostatic pressing, laser cladding, hot/cold spraying, and so on.


We can not only provide relatively mature research on pure tungsten spherical powder but also provide 3D printing services, metal spheroidization services, 3D printing machines and devices .
