ʻO Nichrome, i kapa ʻia ʻo nickel chrome, he mea hoʻohui i hana ʻia e ka hoʻohuihui ʻana i ka nickel, chromium a, i kekahi manawa, hao. Kaulana nui ʻia no kona kūpaʻa wela, a me kona kūpaʻa ʻana i ka ʻino a me ka hoʻowaiwahi ʻelua, pono nui ke kinikini no nā noi he nui. Mai ka hana ʻenehana i ka hana leʻaleʻa, aia ka nichrome i ke ʻano o ka uea i loko o ke ʻano o nā huahana kalepa, nā hana lima a me nā pono hana. ʻIke pū ia i nā noi i nā hoʻonohonoho loea.

ʻO ka uea Nichrome kahi mea i hana ʻia mai nickel a me chromium. Kūpaʻa ia i ka wela a me ka hoʻoweliweli a lawelawe ma ke ʻano he mea hoʻomehana i nā huahana e like me ka toasters a me nā mea maloʻo lauoho. Hoʻohana ka poʻe hobbyist i ka uea nichrome i ke kiʻi pālolo a me ka hana kīʻaha ʻana. Hiki ke loaʻa ka uea i nā hale hana, ke kūkulu a me ka uila pono.

Ma muli o ke kūpaʻa o ka uea nichrome i ka uila, hoʻohana nui ia e like me ka mea hoʻomehana i nā huahana kalepa a me nā pono hana home. Hoʻohana nā mea hoʻomāʻona a me nā mea maloʻo lauoho i nā wili o ka uea nichrome e hana i ka nui o ka wela, e like me nā umu hoʻomoʻa a me nā hoʻomehana hoʻāhu. Hoʻohana pū nā umu hana ʻoihana i ka uea nichrome e holo. Hiki ke hoʻohana ʻia kahi lōʻihi o ka uea nichrome e hana i kahi mea ʻoki wela, hiki ke hoʻohana ʻia ma ka home a i ʻole kahi hoʻonohonoho ʻoihana e ʻoki a hoʻohālikelike i kekahi mau hua a me nā plastics.

Hana ʻia ka uea Nichrome o ke kinikini non-magnet i haku mua ʻia o ka nickel, chromium, a me ka hao. Hoʻohālikelike ʻia ʻo Nichrome e kāna resistivity kiʻekiʻe a me ke kūpaʻa maikaʻi o ka oxidation. ʻO ke kaula uea ʻo Nichrome kahi ductility maikaʻi ma hope o ka hoʻohana ʻana a me ka maikaʻi o ka hiki ke hoʻopaʻa ʻia.

ʻO ka helu e hiki mai ana ma hope o ke ʻano o ka uea Nichrome e hōʻike ana i ka pākēneka o nickel i ke kinikini. ʻO kahi laʻana, "Nichrome 60" kahi ma kahi o 60% Nickel i kāna haku mele.

ʻO nā noi no ka uea Nichrome me nā mea hoʻomehana o nā mea maloʻo lauoho, nā mea hoʻopaʻa wela, a me ke kākoʻo pālolo i nā umu.
