Niobium nicyuma cyoroshye, imvi, kristaline, ibyuma byinzibacyuho bifite aho bihurira cyane kandi birwanya ruswa.Ingingo yo gushonga ni 2468 ℃ hamwe no guteka 4742 ℃.Ni
ni ifite magnetiki nini cyane kuruta ibindi bintu byose kandi ifite nuburyo buhebuje, hamwe no gufata igice gito cya cross neutron.Iyi miterere idasanzwe yumubiri ituma igira akamaro muri super alloys ikoreshwa mubyuma, ikirere, kubaka ubwato, nucleaire, electronics, ninganda zubuvuzi.
