Ni90Cr10 ke motsoako oa austenitic nickel-chromium alloy (NiCr alloy) bakeng sa tšebeliso ea mocheso ho fihlela ho 1200 ° C (2190 ° F). The alloy e khetholloa ka ho hanyetsa ho phahameng, ho hanyetsa oxidation e ntle le botsitso bo botle haholo ba foromo. E na le ductility e ntle ka mor'a tšebeliso le weldability e ntle haholo.
Ni90Cr10 e sebelisetsoa ho futhumatsa lisebelisoa tsa motlakase ka har'a lisebelisoa tsa lapeng le libopi tsa indasteri. Lisebelisoa tse tloaelehileng ke litšepe tse bataletseng, mechini ea ho aena, licheso tsa metsi, ho bopeha ha polasetiki ho shoa, litšepe tsa tšepe, lisebelisoa tsa tšepe tse kentsoeng ka tšepe le likarolo tsa cartridge.
Ka lebaka la thepa e ntle ea ho khomarela ea oxide e holim'a metsi, Ni90C10 e fana ka bophelo bo botle ba ts'ebeletso ha bo bapisoa le li-alloys tsa nickel-chromium tsa tlholisano.
