I-Niobium iyinsimbi ethambile, empunga, ecwebezelayo, ene-ductile enendawo yokuncibilika ephezulu kakhulu futhi imelana nokugqwala.Iphuzu layo lokuncibilika lingu-2468℃ kanye nephuzu elibilayo lingu-4742 ℃.It
Inokungena kazibuthe okukhulu kakhulu kunanoma yiziphi ezinye izakhi futhi inezici ze-superconductive, kanye nesigaba esiphambano sokuthwebula esiphansi sama-neutron ashisayo.Lezi zakhiwo ezibonakalayo eziyingqayizivele zikwenza kube usizo kuma-alloys amakhulu asetshenziswa ezimbonini zensimbi, i-aerospace, i-shipbuilding, i-nuclear, electronics, kanye nezimboni zezokwelapha.
