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.
