I kēia lā, e kamaʻilio kākou e pili ana i kahi metala i loaʻa ma nā wahi a pau o ko kākou ola—ʻo ka aluminika. ʻO ka Aluminum (Aluminium), me ka hōʻailona element Al, he metala māmā keʻokeʻo keʻokeʻo ʻaʻole wale e hōʻike i ka ductility maikaʻi, conductivity uila, a me ka conductivity thermal akā loaʻa pū kekahi ʻano o nā waiwai kino a me nā mea kemika, e hoʻohana nui ʻia i nā kula he nui.
ʻO ka alumini ka mea metala nui loa i loko o ka ʻōpala o ka Honua, ma hope o ka oxygen a me ke silika. He haʻahaʻa kona mānoanoa, a palupalu kona ʻano akā ʻoi aku ka paʻakikī ma mua o ka magnesium, me ka ratio ikaika-a-kaumaha maikaʻi. Hoʻolilo kēia mau waiwai i ka alumini i mea waiwai nui i ka aerospace, ka hana kaʻa, ka ʻoihana kūkulu hale, ka uila, nā mea hoʻopihapiha, a me nā ʻoihana ʻē aʻe he nui.
I ka ʻoihana kūkulu, hoʻohana nui ʻia nā mea alumini i nā puka, nā puka makani, nā pā pale, a me nā ʻōnaehana kākoʻo ma muli o ko lākou kū maikaʻi ʻana i ka wā a me ka maʻalahi o ka hana. Me ka wikiwiki o ka hoʻonaʻauao honua, ke kūpaʻa mau nei ka koi no ka alumini i ka ʻoihana kūkulu hale. ʻO ka ʻili o ka alumini he kiʻiʻoniʻoni pale oxide e pale ai i ka corrosion metala, no laila ua hoʻohana nui ʻia i ka hana ʻana i nā reactors kemika, nā lāʻau lapaʻau, nā lako refrigeration, nā mea hoʻomaʻemaʻe aila, etc.
Loaʻa i ka alumini nā mea hoʻohana nui i nā ʻoihana uila a me nā ʻoihana pale. I ka uila, hoʻohana ʻia ka alumini no ka wela a me nā pahu, hiki ke hoʻopau maikaʻi i ka wela a pale i nā ʻāpana o loko mai ka pōʻino wela. I loko o ka pahu pahu, alumini alumini, ma muli o kāna mau mea pale maikaʻi, hiki ke hoʻokaʻawale maikaʻi i ka māmā, ka oxygen, a me ka maʻa-ʻo nā kumu nui ʻekolu e alakaʻi pinepine ai i ka meaʻai. Ma ka hoʻokaʻawale ʻana i kēia mau mea, hiki i nā mea hoʻopihapiha alumini ke hoʻolōʻihi i ke ola o ka meaʻai a mālama i kāna ʻano meaʻai a me ka ʻono, no laila e hōʻoiaʻiʻo ai i ka maikaʻi o ka huahana a me ka palekana i ka meaʻai a me ka pack pharmaceutical.
Ma muli o kona ikaika māmā, pale ʻana i ka corrosion, a me ka maʻalahi o ka hana ʻana, hoʻohana nui ʻia ka alumini i ka ʻoihana pahu alumini, lilo i mea kūpono no ka hana ʻana i nā hihia alumini like ʻole a me nā hana kiʻekiʻe. Hoʻokō ia i nā pono o nā ʻoihana like ʻole e like me ka nani a me nā salons, nā hui pū ʻana o nā mea hana, nā mea kani, a me nā kamaʻilio uila, a ʻo ia ka casing i makemake ʻia no nā mea kani kiʻekiʻe. I ka meaʻai, lāʻau lapaʻau, a me nā māla ʻē aʻe, hoʻohana pinepine ʻia nā hihia alumini no ka mālama ʻana, lawe ʻana, a kūʻai aku i nā huahana pili ma muli o ko lākou kūpaʻa maikaʻi ʻana i ka wai, nā waiwai pale, a me ka hana insulation thermal.
ʻO ka hoʻohana ākea o nā hihia alumini ma nā māla he mea hiki ʻole ke hoʻokaʻawale ʻia mai ko lākou maʻalahi o ka hana. ʻO ka aluminika a me kāna mau mea hoʻoheheʻe maʻamau he plasticity maikaʻi a hiki ke hana maʻalahi i nā ʻano like ʻole a me nā ʻano nui ma o nā ʻano hana hana plastik e like me ka ʻōwili, extruding, kikoo, a me ka forging. ʻAʻole wale kēia mau ʻano hana e hōʻoia i ka pololei dimensional a me nā waiwai mechanical o nā huahana akā hāʻawi pū kekahi i ka maikaʻi o ka ʻili e hoʻokō i nā koi noi paʻakikī.
Ma keʻano holoʻokoʻa, ma ke ʻano he metala māmā a ikaika, ua hōʻike ʻo alumini i kahi ākea o nā manaʻo noiʻi ma nā kahua he nui. ʻAʻole hoʻokō wale kāna mau waiwai kūʻokoʻa i nā koi noi paʻakikī akā hoʻolaha pū i ka hoʻomohala ʻana a me ka hana hou o nā ʻoihana pili. Manaʻo wau ma o kēia blog, hiki iā ʻoe ke ʻike hohonu i ka alumini a ʻike i ke koʻikoʻi o kēia metala i ko mākou ola.
