Alloy ea motheo ea niobium

C-103 ke motsoako oa niobium o nang le 89% niobium, 10% hafnium le 1% titanium, e ka sebelisoang ho li-nozzles tsa rocket propulsion, joalo ka enjene e kholo ea module ea khoeli ea Apollo. Mojule oa tšebeletso oa Apollo o ne o sebelisa motsoako o fapaneng oa silevera. Kaha niobium e qala ho oxidize ka holimo ho 400 ° C, e le ho e thibela hore e se ke ea e-ba brittle, ho lokela ho sebelisoa lesela le sireletsang holim'a eona.
