Spherical Niobium (Nb) powder has the characteristics of high purity, low oxygen, high sphericity, smooth surface, no satellite, and uniform particle size distribution. Nb, as the lightest refractory metal, has the characteristics of high melting point, high-temperature strength and specific strength, no radioactivity, and so on. Spherical niobium powder is suitable for laser/electron beam augmentation, thermal isostatic pressing, laser cladding, thermal spraying, cold spraying, and so on.

Spherical Niobium Powder Applicable processes

Laser/electron beam additive manufacturing (SLM/EBM, 3D printing), laser direct deposition (DLD), powder hot isostatic pressing (HIP), metal injection molding (MIM), powder metallurgy (PM), laser cladding ( LC), and other processes.

Spherical Niobium Powder Application

Niobium is the lightest refractory metal. It has the characteristics of high melting point, high-temperature strength and specific strength, and no radioactivity. It is the preferred thermal protection material and structural material for aerospace engines. Radiofrequency plasma spheroidized niobium powder has the characteristics of high sphericity, good fluidity, high purity, large loose packing density, the full internal density of the particles, and no hollow powder. It is widely used in palladium materials, vacuum coating, thermal spraying, coating, cold spraying, and other fields.

Spherical Niobium Powder Packaging

Vacuum packaging, 1kg/bag, 2kg/bag; iron drum lined with plastic bag 25 kg/drum; special packaging is available according to user requirements.
