Niobium isimbi yakapfava, grey, crystalline, ductile transition ine nzvimbo yakanyanyisa kunyungudika uye inoshingirira mukuora.Iyo yekunyungudika kwayo i2468 ℃ uye yekubikira nzvimbo 4742 ℃.It
Iyo ine yakakura kwazvo magineti kupinda kupfuura chero zvimwe zvinhu uye zvakare ine superconductive zvimiro, uye yakaderera yekubata muchinjiko chikamu cheanopisa neutron.Izvi zvakasarudzika zvimiro zvemuviri zvinoita kuti zvive zvakakosha muma super alloys anoshandiswa musimbi, aerospace, kuvaka ngarava, nyukireya, zvemagetsi, uye maindasitiri ekurapa.
