I-Niobium yintsimbi ethambileyo, engwevu, eyikristale ene-ductile enendawo yokunyibilika ephezulu kakhulu kwaye iyamelana nokuhlwa.Indawo yayo yokunyibilika yi-2468 ℃ kunye nendawo yokubilisa i-4742 ℃.Yona
inokungena kwemagnethi inkulu kunazo naziphi na ezinye izinto kwaye ikwaneempawu ze-superconductive, kunye necandelo lomnqamlezo olusezantsi lwe-neutron eshushu.Ezi zakhiwo zikhethekileyo zomzimba zenza ukuba zibe luncedo kwii-alloys eziphezulu ezisetyenziswa kwintsimbi, i-aerospace, ukwakha iinqanawa, inyukliya, i-electronics, kunye namashishini ezonyango.
