Niobium Powder (Nb Metal Powder)
We provide niobium metal powder with purity 99.8% & 99%, niobium powder can be widely used in many fields.
Applications for niobium powder:
• High-temperature components, especially for the aerospace industry
• Alloy additions, including some for superconducting materials
• Plasma spray coatings
• Filters
• Certain corrosion-resistant applications
Physical properties of Nb metal powder:
Nb powder is in light grey, with high melting point and good resistance to corrosion.
Packing of Nb powder: Outer fiber drum or carton, inner two layer plastic bag.

We also provide spherical niobium powder with excellent fluidity, it is a material for 3D printing. Nb metal powder can produce the metal objects directly with high density and accurate shape by DMLS (direct metal laser sintering), which is a typical 3D printing technique. The particle size of our spherical niobium powder will be 1-15um,15-53um, 45-105um or customized diameter, purity of 99.9%. Please send us your inquiry to sales@edge-techind.com.
