About Niobium

Niobium is a refractory metal with the most concentrated supply of any critical mineral, with Brazil accounting for roughly 90% of global production. Small additions of niobium to steel dramatically improve strength and reduce weight, making it essential for automotive, pipeline, and structural applications. It is also critical for superconducting magnets used in MRI machines and particle accelerators.
