ʻO Nichrome, i ʻike ʻia hoʻi he nickel chrome, he mea hao i hana ʻia e ka hui ʻana i ka nickel, chromium a, i kekahi manawa, hao. ʻIke maikaʻi ʻia no kona pale ʻana i ka wela, a me kona kūpaʻa ʻana i ka corrosion a me ka oxidation, ʻoi aku ka maikaʻi o ka alloy no kekahi mau noi. Mai ka hana ʻenehana a hiki i ka hana leʻaleʻa, aia ka nichrome i ke ʻano o ka uea i nā ʻano huahana pāʻoihana, nā mea hana a me nā mea hana. Loaʻa iā ia nā noi ma nā hoʻonohonoho kūikawā.
ʻO ka uea Nichrome kahi mea i hana ʻia mai ka nickel a me ka chromium. Kū'ē ia i ka wela a me ka oxidation a lawelawe ma ke ʻano he mea wela i nā huahana e like me nā toasters a me nā mea maloʻo lauoho. Hoʻohana ka poʻe leʻaleʻa i ka uea nichrome i ke kiʻi kiʻi seramika a me ka hana aniani. Hiki ke loaʻa ka uea i loko o nā laboratories, kūkulu hale a me nā mea uila kūikawā.
Ma muli o ka pale ʻana o ka uea nichrome i ka uila, he mea hoʻohana nui ia ma ke ʻano he mea hoʻomehana i nā huahana kalepa a me nā mea hana home. Hoʻohana nā mea hoʻoheheʻe 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 toaster a me nā mea hoʻomehana mālama. Hoʻohana pū nā kapuahi ʻoihana i ka uea nichrome e hana. Hiki ke hoʻohana ʻia ka lōʻihi o ka uea nichrome no ka hana ʻana i kahi mea ʻoki uea wela, hiki ke hoʻohana ʻia ma ka home a i ʻole ma kahi ʻoihana e ʻoki a hoʻohua i kekahi mau pua a me nā plastics.
Hana ʻia ka uea Nichrome me kahi huila non-magnetic i haku mua ʻia me ka nickel, chromium, a me ka hao. Hōʻike ʻia ʻo Nichrome e kona resistivity kiʻekiʻe a me ke kūpaʻa oxidation maikaʻi. Loaʻa ka ductility maikaʻi ʻo Nichrome ma hope o ka hoʻohana ʻana a me ka weldability maikaʻi loa.
ʻO ka helu e hiki mai ana ma hope o ke ʻano uea Nichrome e hōʻike ana i ka pākēneka o ka nickel i loko o ka alloy. No ka laʻana, "Nichrome 60" aia ma kahi o 60% Nickel i kāna haku.
ʻO nā noi no ka uea Nichrome me nā mea hoʻomehana o nā mea maloʻo lauoho, nā mea hoʻopaʻa wela, a me ke kākoʻo keramika i nā kiln.
