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.
