ʻO ka helu heheʻe o ka niobium he 2468 Dc, a ʻo ka mānoanoa o ia mea he 8.6 g/cm3. Me nā hiʻohiʻona o ka pale ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe a me ka malleability, hoʻohana nui ʻia ka niobium i ka ʻoihana uila, ʻoihana kila, ʻoihana kemika, optics, hana pōhaku pōhaku, ʻenehana superconducting, aerospace. ʻenehana a me nā ʻoihana ʻē aʻe. ʻO ka pepa Niobium a me ka paipu / paipu ke ʻano maʻamau o ka huahana Nb.
