Nā pōmaikaʻi o nā papa hōʻailona alumini

Ma waena o nā huahana hōʻailona metala, ʻoi aku ka nui o nā papa hōʻailona alumini ma mua o 90% o nā papa inoa metala. No ka hapalua o ke kenekulia, ua hoʻohana ʻia nā papa alumini e hana i nā papa hōʻailona, ​​e mau ana. ʻO ke kumu nui ʻo ka alumini ka mea hoʻonaninani loa. Hiki ke hoʻohana ʻia a hoʻohana ʻia i nā kaʻina hana hoʻonaninani he nui i ka aluminika, kahi kūpono no ka loaʻa ʻana o nā papa hoʻonaninani kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, ua hoʻoholo ʻia e ke ʻano o nā waiwai maikaʻi o ka alumini.

Nā hiʻohiʻona o ka alumini: Ma waho aʻe o nā kumu i luna, ua kūlike nā ʻano kino a me nā kemika o ka alumini me nā koi e pili ana i ka noi ʻana i nā papa hōʻailona. He hoʻolauna pōkole kēia.

1. Kaumaha māmā ʻO ka nui o ka alumini he 2.702gNaN3, he 1/3 wale nō ia o ke keleawe a me ka alumini. ʻAʻole e hoʻonui nā papa hōʻailona alumini i ke kaumaha o nā mea hana a mālama pū i nā kumukūʻai.

2. ʻO ka maʻalahi o ka hana ʻana ʻo ka alumini he ductility maikaʻi loa, maʻalahi ke ʻoki, a maʻalahi ke hoʻopaʻa ʻia a me ke ʻano, hiki ke hoʻokō i nā pono o nā kaʻina hana hōʻailona kūikawā.

3. ʻO ke kūpaʻa ʻino maikaʻi Hiki ke hana ʻia kahi kiʻi ʻoniʻoni paʻakikī a paʻakikī ma luna o ka ʻili o ka aluminika a me kāna mau ala.
4. ʻAʻole ʻino ke kiʻi ʻoniʻoni alumini oxide maikaʻi i nā mea he nui, a maikaʻi loa kona kūpaʻa i nā wahi paʻakikī i nā wahi ʻoihana a me nā wahi kahakai.
5. ʻAʻohe magnetism ʻO ka alumini he kino magnetic ʻole, a ʻaʻole e hoʻopilikia nā hōʻailona alumini i waho i nā mea kani a me nā mea hana.
6. Waiwai waiwai ʻO ka hoʻopuka makahiki o ka alumini ka lua wale nō ma mua o ke kila, ke kūlana lua ma ka huina metala o ka honua.
