Niobium Plate & Board & Sheet Description
Niobium (Nb) is a shiny gray metal with a melting point of 2468°C, a boiling point of 4742°C, and a density of 8.57g/cm³. High-purity niobium metal has higher ductility, but will harden as the impurity content increases. Niobium has a very low capture cross section for thermal neutrons, so it is quite useful in the nuclear industry. Stanford Advanced Materials (SAM) is a trust-worthy supplier of high-quality Niobium Plate & Board & Sheet.
