Product details

Stardust company provide spherical chrome powder with high purity, low oxygen, high sphericity , smooth surface, no satellite spheres,  bare hollow particle, uniform particle size distribution, excellent flow properties, and high bulk density and tap density.

Tantalum has excellent biocompatibility. The tantalum implant formed by 3D printing has the elastic modulus closest to human cartilage tissue, making it the most ideal orthopedic implant material. 

Spherical molybdenum powder is suitable for laser/electron beam additive manufacturing,  hot isostatic pressing,  laser cladding, hot/cold coating and other processes.


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