Niobium Powder

We provide niobium metal powder purity 99% & 99.8%, 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 niobium powder:
Niobium powder is in light grey, with high melting point and good resistance to corrosion.
Packing of Niboum powder: Packed with plastic bottles in cartons.

We also provide spherical niobium metal powder, it is a material for 3D printing. Niboum 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 1um,10um, 45um or customized diameter, purity of 99.9%. Please send us your inquiry to sales@edg-techind.com.
