I kēia lā, e kamaʻilio kākou e pili ana i kahi metala i ʻike nui ʻia i ko kākou ola—ʻo ia hoʻi ka alumini. ʻO ka alumini (Aluminium), me ka hōʻailona element Al, he metala māmā keʻokeʻo-hina e hōʻike ana i ka ductility maikaʻi, ka conductivity uila, a me ka conductivity wela akā loaʻa pū kekahi mau ʻano kino a me nā kemika kū hoʻokahi, e hoʻohana nui ʻia ana ma nā ʻano he nui.
ʻO ka alumini ka mea hao nui loa i loko o ka ʻili o ka Honua, ma hope o ka oxygen a me ka silicon. He haʻahaʻa kona nui, a he palupalu kona ʻano akā ʻoi aku ka paʻakikī ma mua o ka magnesium, me ka lakio ikaika-a-kaumaha maikaʻi. ʻO kēia mau waiwai e hoʻolilo i ka alumini i mea nui i ka aerospace, ka hana kaʻa, ka ʻoihana kūkulu hale, nā mea uila, nā mea hoʻopili, a me nā ʻoihana ʻē aʻe he nui.
I loko o ka ʻoihana kūkulu hale, hoʻohana nui ʻia nā mea alumini i nā puka, nā puka makani, nā paia pale, a me nā ʻōnaehana kākoʻo kūkulu ma muli o ko lākou kūpaʻa maikaʻi i ka wā a me ka maʻalahi o ka hana ʻana. Me ka wikiwiki o ke kūlanakauhale honua, ke kūpaʻa nei ke koi no ka alumini i loko o ka ʻoihana kūkulu hale a ke ulu nei. Loaʻa i ka ʻili o ka alumini kahi ʻili pale oxide mānoanoa e pale ai i ka pala o ka metala, no laila ua hoʻohana nui ʻia i ka hana ʻana i nā reactors kemika, nā mea lapaʻau, nā lako hoʻomaʻalili, nā lako hoʻomaʻemaʻe aila, a pēlā aku.
He nui nā noi o ka alumini i nā ʻoihana uila a me nā ʻoihana hoʻopili. I loko o nā mea uila, hoʻohana ʻia ka alumini no nā poho wela a me nā pahu, hiki ke hoʻokuʻu pono i ka wela a pale i nā ʻāpana o loko mai ka pōʻino wela. Ma ke kahua hoʻopili, hiki i ka pepa alumini, ma muli o kona mau waiwai pale maikaʻi, ke hoʻokaʻawale pono i ka mālamalama, ka oxygen, a me ka makū—ʻo nā kumu nui ʻekolu e alakaʻi pinepine ai i ka palaho ʻana o ka meaʻai. Ma ka hoʻokaʻawale ʻana i kēia mau kumu, hiki i nā mea hoʻopili alumini ke hoʻolōʻihi i ke ola o ka papa o ka meaʻai a mālama i kona ʻike meaʻai a me kona ʻono, no laila e hōʻoiaʻiʻo ana i ka maikaʻi a me ka palekana o ka huahana i ka meaʻai a me ka hoʻopili lāʻau lapaʻau.
Ma muli o kona ikaika māmā, kūpaʻa i ka pala, a me ka maʻalahi o ka hana ʻana, hoʻohana nui ʻia ka alumini i loko o ka ʻoihana hihia alumini, e lilo i mea kūpono no ka hana ʻana i nā hihia alumini like ʻole a me ka hana kiʻekiʻe. Hoʻokō ia i nā pono o nā ʻoihana like ʻole e like me ka nani a me nā salona, nā hui pū ʻana o nā mea hana, nā mea kani, a me nā kamaʻilio uila, a ʻo ia ka pahu makemake ʻia no nā mea kani kiʻekiʻe. I loko o ka meaʻai, nā lāʻau lapaʻau, a me nā ʻoihana ʻē aʻe, hoʻohana pinepine ʻia nā hihia alumini no ka mālama ʻana, ka lawe ʻana, a me ke kūʻai aku ʻana i nā huahana pili ma muli o ko lākou kūpaʻa maikaʻi i ka makū, nā waiwai pale, a me ka hana insulation thermal.
ʻO ka hoʻohana nui ʻana o nā hihia alumini ma nā ʻano like ʻole, ʻaʻole hiki ke hoʻokaʻawale ʻia mai ko lākou maʻalahi o ka hana ʻana. Loaʻa i ka alumini a me kāna mau mea hoʻohuihui ka plasticity maikaʻi a hiki ke hana maʻalahi ʻia i nā ʻano like ʻole a me nā nui ma o nā ʻano hana plastik e like me ka ʻōwili ʻana, extruding, stretching, a me ka forging. ʻAʻole wale kēia mau ʻano hana e hōʻoia i ka pololei o ka dimensional a me nā waiwai mechanical o nā huahana akā hāʻawi pū i ka maikaʻi o ka ʻili e hoʻokō i nā koi noi paʻakikī like ʻole.
Ma keʻano laulā, ma ke ʻano he metala māmā a ikaika hoʻi, ua hōʻike ka alumini i nā ʻano manaʻolana noi like ʻole ma nā ʻano like ʻole. ʻAʻole wale kona mau waiwai kū hoʻokahi e hoʻokō i nā koi noi paʻakikī like ʻole akā e paipai pū i ka hoʻomohala ʻana a me ka hana hou ʻana o nā ʻoihana pili. Manaʻolana wau ma o kēia blog, hiki iā ʻoe ke loaʻa kahi ʻike hohonu o ka alumini a ʻike i ke koʻikoʻi o kēia metala i ko mākou ola.
