Niobium Powder

Niobium is a lustrous, grey, ductile, paramagnetic metal. Like tantalum, niobium also features outstanding chemical and oxidation resistance. Niobium powder can be added to iron or nickel to produce alloys in the aerospace, medical and electronics industries. 90% niobium powder is used to produce high-grade structural steel, followed by its use in superalloys.

Niobium Powder Features

• Physical properties: Light gray powder, Excellent melting point and corrosion resistance

• Application: Used as additive of alloy and production of welding electrode

Spherical Niobium Powder

AEM’s spherical niobium metal powder is also a material for 3D printing. It 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 combination of low oxygen content, spherical shape and excellent flowability makes our powders perfectly printable and contributes to achieve outstanding characteristics of 3D printed parts.
