High Sphericity: Particles are perfectly solid spheres with excellent flowability, ensuring uniform and continuous powder feeding without nozzle clogging or bridging.
High Deposition Efficiency: The high apparent density and stable in-flight velocity of these spherical particles result in significantly higher deposition efficiency compared to crushed (angular) powders.
