Niobium Powder
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
