ʻO ka alumini he metala keʻokeʻo kālā, ʻo ka mea i loko o ka ʻōpala ma hope o ka oxygen a me ke silika i ke kolu. He ʻuʻuku ka nui o ka alumini, i kapa ʻia ke metala māmā. ʻO ka alumini ka hana a me ka hoʻohana ʻana i nā metala non-ferrous kiʻekiʻe, ka honua ma hope o ke kila. ʻO ka nui o ka alumini e pili ana i ke kila, ke keleawe keleawe ma kahi o 1/3. ʻOiai he māmā ka mea alumini, no laila hoʻohana mau ʻia i ka hana ʻana, nā kaʻaahi, nā subways, nā kaʻa, nā mokulele, nā moku, nā rockets a me nā ʻāina ʻē aʻe, ke kai a me ka ea e hoʻemi i ka ukana e hoʻonui i ke kaumaha. Pēlā nō, ʻo ka alumini i nā huahana pūʻali koa ke kūlana koʻikoʻi.
ʻO ka alumina, ka mea i ʻike ʻia ʻo ka alumini oxide, he pauka keʻokeʻo. ʻO ka alumini electrolytic kahi ʻano o ka hoʻoheheʻe ʻana i ka metala alumini, maʻamau i loko o ke kelepona electrolytic ma o ke ʻano kiʻekiʻe i ka decomposition o ka alumini oxide alumini.
Aia ka alumini i ke kaʻina electrolysis mai loko mai o ka wai alumini wai wai, me ka ʻole o ka ua a me nā lāʻau lapaʻau ʻē aʻe. Hiki i ka alumini kumu ke lilo i alumini ingots ma ke komo ʻana i ke kumu hoʻohālike alumini. No laila, ʻo ka alumina ka mea maka o ka wai alumini, ka alumini electrolytic ke kaʻina hana, ʻo ka alumini kumu ka kaʻina electrolysis o ka wai alumini, ka alumini ingot kahi huahana alumini, hiki i ka mākeke hope loa ke kūʻai aku i nā huahana.
Aluminum ingots e like me nā ʻāpana like ʻole o ka alumini alumini maʻemaʻe kiʻekiʻe, nā alumini alumini a me ka remelting me ka alumini ingot ʻekolu; e like me ke ʻano a me ka nui hiki ke hoʻokaʻawale ʻia i nā ingots, plate ingots, bar, t-ing a me nā mea he nui.
