ʻO Ni80Cr20 kahi hui nickel-chromium (NiCr alloy) i hōʻike ʻia e ke kū'ē kiʻekiʻe, ke kūpaʻa oxidation maikaʻi a me ke kūpaʻa maikaʻi loa. He kūpono ia no ka hoʻohana ʻana i nā mahana a hiki i 1200°C, a paʻa i kahi ola lawelawe kiʻekiʻe i hoʻohālikelike ʻia me nā hui Iron chromium alumium.
ʻO nā noi maʻamau no Ni80Cr20 he mau mea hoʻomehana uila i nā mīkini home, nā umu ʻoihana a me nā pale (nā pale wili uila, nā pale ʻili metala), nā hao pālahalaha, nā mīkini hao, nā mea hoʻomehana wai, nā make hoʻoheheʻe plastik, nā hao soldering, nā mea tubular i uhi ʻia me ka metala a me nā mea cartridge.
