Ni70Cr30ke nickel-chromium alloy (NiCr alloy) e khetholloang ka ho hanyetsa ho phahameng, khanyetso e ntle ea oxidation le botsitso ba sebopeho se setle haholo. E loketse ho sebelisoa ka mocheso ho fihlela ho 1250 ° C, 'me e boloka bophelo bo botle ba tšebeletso ha e bapisoa le li-alloys tsa Iron chromium aluminium.
Lisebelisoa tse tloaelehileng tsa Ni70Cr30 ke lisebelisoa tse futhumatsang tsa motlakase ka har'a lisebelisoa tsa lapeng, liindasteri le li-resistors (li-resistors tsa wirewound, li-resistors tsa tšepe tsa tšepe), litšepe tse bataletseng, mechini ea tšepe, licheso tsa metsi, ho bōptjoa ha polasetiki ho shoa, litšepe tsa tšepe, lisebelisoa tsa tšepe tse kentsoeng ka tšepe le likarolo tsa cartridge.
