Uea Palahalaha Hai-Nicr70noNā ʻōwili pālua Mea kū'ē paleki
Ni70Cr30he nickel-chromium alloy (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 1250°C, a paʻa i kahi ola lawelawe kiʻekiʻe i hoʻohālikelike ʻia me nā Iron chromium alumium alloys.
Nā noi maʻamau noNi70Cr30he mau mea hoʻomehana uila i loko o nā mīkini home, nā umu ʻoihana a me nā resistors (nā resistors wirewound, nā resistors kiʻiʻoniʻoni 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.
