Ubuninzi bensimbi engenasici yi-7.7 g / cm³. Xa insimbi engenasici isetyenziswe kwiinkqubo ezahlukeneyo kumashishini ahlukeneyo, iyanciphisa ixesha lokuhambisa elithathwe ngamacandelo enziwe ngensimbi engenasici. Oku kungenxa yokuba, ngenxa yokusebenzisa insimbi engenasici, akukho mfuneko yokuba kugqitywe ukwenziwa. Insimbi engenasici ine-ductility ephezulu kunye nesantya esiphezulu sokuqina komsebenzi. Intsimbi engatyiwayo inamandla ashushu aphezulu kunye nokuqina okuphezulu kwe-cryogenic. Insimbi engenasici ifumaneka kumabakala angaphezu kwama-150, kodwa amabakala angama-15 kuphela asetyenziswa ngokuqhelekileyo. Eyona nto intle ngentsimbi engatyiwayo kukuba i-100% inokuphinda isetyenziswe.
