Ni70Cr30ʻO ia ka nickel-chromium alloy (NiCr alloy) i hōʻike ʻia e ka resistivity kiʻekiʻe, ke kūpaʻa oxidation maikaʻi a me ke kūpaʻa ʻano maikaʻi loa. He kūpono ia no ka hoʻohana ʻana i nā mahana a hiki i 1250 ° C, a paʻa i kahi ola lawelawe ʻoi aku ka maikaʻi e hoʻohālikelike ʻia me nā alloys Iron chromium alumium.
