Spherical Niobium (Nb) Powder

Spherical Niobium (Nb) powder is the perfect thermal protection material and structural material for aerospace engines. Nb, as the lightest refractory metal, has the characteristics of high melting point, high-temperature strength, high specific strength, and no radioactivity.

Spherical Niobium (Nb) Powder Characteristics

• High purity (≥99.9%)
• Low oxygen
• High sphericity (≥98%)
• Smooth surface
• No satellite spheres
• Uniform particle size distribution
• Excellent flow properties 
• High bulk density and tap density

Spherical Niobium (Nb) 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)

Spherical Niobium (Nb) Powder Application

• Used in thermal protection material and structural material for aerospace engines.
• Used in palladium materials, vacuum coating, thermal spraying, coating, cold spraying, and other fields.
