ʻO Ni80Cr20 kahi 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 1200 ° C, a paʻa i kahi ola lawelawe ʻoi aku ka maikaʻi i hoʻohālikelike ʻia me nā alloys Iron chromium alumium.
ʻO nā noi maʻamau no Ni80Cr20 he mau mea hoʻomehana uila i nā mea hana hale, nā umu ahi a me nā mea pale (nā mea pale uila, nā mea pale kiʻi metala), nā hao pālahalaha, nā mīkini hao, nā mea hoʻomehana wai, nā mea hoʻoheheʻe palaki, nā hao hao, nā mea tubular metala a me nā mea pahu pahu.
