ʻO ka alumini ka mea metala he metala māmā keʻokeʻo kālā keʻokeʻo.Hoʻohana pinepine ʻia nā mea kūʻai i nā koʻokoʻo, nā lau, nā pepa, nā pauka, nā lipine a me nā filament.I loko o ka ea mākū, hiki iā ia ke hana i kahi kiʻiʻoniʻoni oxide e pale ai i ka corrosion metala.Hiki i ka pauka alumini ke puhi ikaika i ka wā e wela ai i ka lewa, a e hoʻokuʻu i kahi lapalapa keʻokeʻo.Hiki ke hoʻoheheʻe ʻia i loko o ka dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble i ka wai.ʻAno pili 2.70.Ka helu hehee 660 ℃.Ka helu hoʻolapalapa 2327 ℃.ʻO ka maʻiʻo o ka aluminika i loko o ka ʻōpala o ka honua ka lua wale nō i ka oxygen a me ke silikoni, ke kūlana kolu, a ʻo ia ka mea metala nui loa i ka ʻōpala o ka honua.ʻO ka hoʻomohala ʻana o nā ʻoihana koʻikoʻi ʻekolu o ka mokulele, ke kūkulu ʻana a me nā kaʻa e pono ai i nā waiwai waiwai e loaʻa nā waiwai kūʻokoʻa o ka alumini a me kāna mau ala, e hoʻomaʻamaʻa nui i ka hana a me ka hoʻohana ʻana i kēia alumini metala hou.He ākea loa ka noi.
01. ʻO ke kaumaha māmā, ka ikaika kikoʻī kiʻekiʻe a me ke kūpaʻa corrosion o ka alumini nā hiʻohiʻona koʻikoʻi o kāna hana.He haʻahaʻa haʻahaʻa loa ka alumini he 2.7 g/cm wale nō
ʻOiai he palupalu, hiki ke hana ʻia i loko o nā alumini alumini like ʻole, e like me ka alumini paʻa, ke alumini paʻakikī, ka alumini rust-proof, ka alumini hoʻolei, a me nā mea ʻē aʻe. ʻoihana hana.Eia kekahi, hoʻohana pū kekahi i nā rockets space, space shuttles, a me nā satellite artificial i ka nui o ka alumini a me kāna mau alumini alumini.
02. He kiʻekiʻe ka ikaika kūikawā o ke alumini alumini
03. Ke kū'ē i ka corrosion maikaʻi
ʻO ka alumini he metala hoʻoheheʻe loa, akā paʻa ia i nā kaiapuni oxidizing maʻamau.ʻO kēia ka hoʻokumu ʻana i kahi kiʻiʻoniʻoni oxide ma ka ʻili o ka alumini i ka oxygen, oxygen a me nā mea ʻona ʻē aʻe.ʻO ke kiʻi alumini oxide ʻaʻole wale ka ikaika o ka corrosion kūʻē, akā loaʻa kekahi ʻano o ka insulation.
04. ʻO ka conductivity o ka alumini ka lua wale nō i ke kālā, ke keleawe a me ke gula
ʻOiai ʻo kona conductivity he 2/3 wale nō o ke keleawe, ʻo kona mānoanoa he 1/3 wale nō o ke keleawe, no laila e hoʻouna i ka nui o ka uila, ʻo ka maikaʻi o ka uea alumini he hapalua wale nō o ka uea keleawe.No laila, he nui ka hoʻohana ʻana o ka alumini i ka ʻoihana hana ʻenehana uila, ka uea a me ke kelepona a me ka ʻoihana lekiō.
05. ʻO ka alumini ka mea lawe wela maikaʻi
He 3 manawa oi aku ka nui o kona conductivity wela ma mua o ko ka hao a he 10 ka nui o ko ke kila kila.Hiki ke hoʻohana ʻia ka alumini i ka ʻoihana e hana i nā mea hoʻololi wela like ʻole, nā mea hoʻopau wela a me nā mea kuke.
06. ʻO ka alumini ka ductility maikaʻi
ʻO ia ka lua ma mua o ke gula a me ke kālā i ka ductility a hiki ke hana ʻia i nā foil ʻoi aku ka lahilahi ma mua o 0.006 mm.Hoʻohana nui ʻia kēia mau pahu alumini no ka hoʻopili ʻana i nā cigakeke, nā kukui, a me nā mea ʻē aʻe.Hiki ke ʻoki, wili ʻia a welded i ka alumini e nā ʻano hana maʻamau.
07. ʻAʻole magnetic ka alumini
ʻAʻole ia e hoʻoulu i nā māla magnetic ʻē aʻe a ʻaʻole hoʻopilikia i nā mea hana pololei.
08. Loaʻa i ka alumini nā mea kani, a ʻoi aku ka maikaʻi o ka hopena kani
No laila, hoʻohana ʻia ka alumini no nā kaupaku i nā lumi hoʻolaha a me nā hale nui o kēia wā.
