Niobium Powder

InquiryData sheet

Description of Niobium Powder:

Niobium is a lustrous, grey, ductile, paramagnetic metal. It is characterized by a high melting point of 2,477°C and a density of 8.58g/cm³. Niobium can be easily formed, even at low temperatures. Niobium has physical and chemical properties similar to those of the element tantalum, and the two are therefore difficult to distinguish. Like tantalum, niobium also features outstanding chemical and oxidation resistance.
Niobium can be electrically heated and anodized to a wide variety of colors that makes it very attractive in the jewelry industry. Niobium is added to iron or nickel to produce alloys in the aerospace, medical and electronics industries. 90% Niobium was used in the production of high-grade structural steel, followed by its use in superalloys.
AEM can provide niobium metal powders as well as niobium semi-finished and finished products with high quality and competitive prices.
