Niobium Foil / Strip
Description
Niobium (Nb) is very stable so that it can replace stainless steel in the inorganic acid produce leading to an extended service life of the machine for about dozens of times. Roughly 90% of Niobium is used in the production of high-grade structural steel, a great deal in the form of the niobium sheet, followed by its use in superalloys.
Alfa Chemistry supplies a wide range of niobium foil / strip which are highly acclaimed due to its good luster, ductility, high conductivity and high quality. We can also customize various shapes of niobium products according to your requirements or drawings.
