Niobium Sheet / Plate
Description

Niobium (Nb) is a greyish-silvery metal found in group 5 & period 5 on the periodic table. Niobium is a fairly dense and ductile element which is similar to tantalum. Because of the oxide layer that forms on its surface, Niobium is very resistant to corrosion. Due to its unique attributes, Niobium is the refractory metal of choice for a wide variety of interesting applications.
Alfa Chemistry specializes in providing high quality niobium Sheet & Plate on the market today. We can also customize various shapes of niobium products according to your requirements or drawings.
