Niobium Sheet & Niobium Plate
We provide niobium rolling product with thickness 0.03mm to 10mm. Rolling niobium products: sheet, plate (board), foil, strip & ribbon.
Material: R04200-1, R04210-2, 99.9% pure
Specification: As per ASTM B393
Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties, it resembles tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, halogens, nitrogen, and sulfur. The metal is inert to acids, even to aqua regia at room temperatures, but is attacked by hot, concentrated acids, and especially by alkalis and oxidizing agents.3
