Indawo encibilikayo ye-niobium ngu-2468 Dc, futhi ukuminyana kwayo ngu-8.6 g/cm3. Ngezimpawu zokumelana nokugqwala, ukumelana nokushisa okuphezulu kanye nokusebenziseka kalula, i-niobium isetshenziswa kabanzi embonini ye-elekthronikhi, imboni yensimbi, imboni yamakhemikhali, i-optics, ukukhiqizwa kwamatshe ayigugu, ubuchwepheshe be-superconducting, i-aerospace. ubuchwepheshe kanye neminye imikhakha. Ishidi le-Niobium kanye neshubhu/ipayipi kuyindlela evame kakhulu yomkhiqizo we-Nb.
