Mea Hana Kiekie Metala Elevator Palekana Puka Puka ahi

Ma ke ʻano he mea metala māmā, ua hōʻike nā alumini alumini i nā pōmaikaʻi nui ma nā kula he nui. ʻO kēia nā mea maikaʻi nui o nā alumini alumini:

Māmā:
ʻO ka nui o nā alumini alumini kokoke i 2.7g / cm³, ʻo ia ka 1/3 o ka hao a i ʻole ke keleawe, e hoʻomāmā a maʻalahi nā huahana i hana ʻia me nā alumini alumini.
No ka laʻana, i ka ʻoihana aerospace a me ka ʻoihana kaʻa, hiki i ka hoʻohana ʻana i nā mea alumini alumini hiki ke hoʻemi nui i ke kaumaha o nā mokulele a me nā kaʻa, hoʻomaikaʻi i ka pono o ka wahie a me ka hana.

ikaika kiʻekiʻe:
Ma hope o kekahi pae o ka hana anu a i ʻole ka mālama wela, hiki ke hoʻoikaika ʻia ka ikaika o ka matrix, a hiki ke hoʻoikaika hou ʻia kekahi mau māka o nā alumini alumini e ka mālama wela.
Loaʻa i nā alumini alumini ka lākiō kiʻekiʻe o ka ikaika a me ke kaumaha, ʻoi aku ka māmā ma mua o ke kila akā ua like ka ikaika, a kūpono no ka hana ʻana i nā ʻāpana hana e halihali i nā ukana nui.

ʻO ka pale ʻana i ka corrosion maikaʻi:
Hoʻokumu maʻalahi ʻia kahi kiʻiʻoniʻoni pale alumini paʻa paʻa (Al₂O₃) ma ka ʻili o nā alumini alumini, hiki ke pale pono i ka matrix mai ka ʻino.
I loko o ka moana kai, hiki i nā alumini alumini ke pale aku i ka erosion o ka wai paʻakai, no laila ua hoʻohana nui ʻia i nā moku a me nā hale kai.

Maikaʻi ka uila a me ka thermal conductivity:
ʻO ka conductivity uila a me ka wela o ka alumini ka lua wale nō i ke kālā, keleawe a me ke gula, a he mea maikaʻi loa ka wela a me ka uila.
I nā lako uila, ʻo ka conductivity uila kiʻekiʻe o ka alumini alumini e kōkua i ka hōʻoia ʻana i ka hoʻoili paʻa o kēia manawa a hoʻomaikaʻi i ka hana a me ke kūpaʻa o nā mea hana.

Maʻalahi e hana:
Ma hope o ka hoʻohui ʻana i kekahi mau mea hoʻohui, hiki i ka alumini alumini ke loaʻa ka hana hoʻolei maikaʻi a me ka hoʻoili ʻana i ka plasticity.
Hiki ke hoʻokumuʻia ka alumini alumini ma o nā kaʻina hana likeʻole e like me ka extrusion, ka hoʻoleiʻana, ka forging, a me nā mea'ē aʻe e hoʻokō i nā koi hoʻolālā o nā huahana likeʻole.

Palekana kaiapuni a me ka mālama ikehu:
ʻO ka alumini alumini he mea hana hou me ka lubricity maikaʻi, hiki ke hōʻemi i ka hoʻohana ʻana i ka ikehu a me ka lole mīkini i ka wā o ka hana.
ʻO ka hana hou ʻana a me ka hoʻohana hou ʻana i ke alumini alumini e kōkua i ka hōʻemi ʻana i ka noi no nā kumuwaiwai kūlohelohe a hōʻemi i ka hoʻokuʻu ʻana o ka ʻōpala, e hoʻokō ana i nā koi o ka mālama ʻana i ke kaiapuni a me ka hoʻomohala mau.
