Naichrome / Element ElellPale aku ka hoʻohuli/ Pā'ālua
Ni80c20he nokel-chrominut-chromium alloy (niy alloy) i hōʻikeʻia e ka resistivity kiʻekiʻe, maikaʻi o ka oxidation maikaʻi a maikaʻi loa. He kūpono no ka hoʻohanaʻana i nā mahana e hiki ai i 1200 ° C, a hoʻopaʻa i kahi ola lawelawe i hoʻohālikelikeʻia i nā allona Chromium Anum.
Nā noi maʻamau no ni80cr20 i nā mea eʻoi aku ai i nā mea hana ma nā hale kūʻai, nā mea kūʻai aku, nā mea kūʻai aku.
