Spherical Niobium Powder

Product Code : 3D-Nb-CU-PO1

Spherical Niobium Powder

Niobium is the lightest refractory metal.Niobium is the refractory metal with high melting point, high temperature strength and specific strength, but no radioactivity. It is the preferred thermal protection material and structural material for aerospace engines. Radio frequency plasma spheroidized niobium powder has the characteristics of high sphericity, good fluidity, high purity, high bulk density, full density inside the particle, and no hollow powder. It is widely used in palladium materials, vacuum coating and thermal spraying coating, cold spraying, and other fields.
