Hoʻopili ʻia nā kaʻa kaʻa holo kiʻekiʻe me ka alumini, a hele kekahi mau laina kaʻaahi kiʻekiʻe ma ke kaʻina anu o ka emi ʻana o 30 degere Celsius; ʻO kekahi mau mea hana, nā mea hana a me nā mea e pono ai i kēlā me kēia lā ma ka moku noiʻi ʻepekema Antarctic i hana ʻia me ka alumini a pono e kū i nā hoʻokolohua Celsius kanaonokumamāhiku degere Celsius; ʻO kekahi o nā mea hana ma nā moku kalepa mai Kina mai a hiki i ʻEulopa a hiki i ʻEulopa, ua hana ʻia me ka alumini, ʻo kekahi o ia mau mea i ʻike ʻia ma waho, a ʻo ka wela hoʻi he 560 degere Celsius;

Hiki iā lākou ke hana maʻamau i kahi ʻano anu?

ʻO ka pane 'ʻAʻohe pilikia, ʻo ka alumini alumini a me ka huahana alumini ka mea makaʻu loa i ke anu a me ka wela.

ʻO ka alumini a me ka alumini nā mea haʻahaʻa haʻahaʻa maikaʻi loa. ʻAʻohe o lākou palupalu haʻahaʻa wela. ʻAʻole lākou e like me ka haʻahaʻa haʻahaʻa haʻahaʻa e like me ke kila maʻamau a me nā nickel alloys. Hoʻonui ka ikaika o ko lākou mau waiwai me ka mahana, akā e hahai ana ka plasticity a me ka paʻakikī. Hoʻemi ʻia ka emi ʻana o ka mahana, ʻo ia hoʻi, nui ka brittleness haʻahaʻa haʻahaʻa. Eia naʻe, ʻokoʻa loa nā alumini alumini a me nā alumini, a ʻaʻohe ʻike o ka brittleness haʻahaʻa haʻahaʻa. Hoʻonui nui ʻia ko lākou mau waiwai mechanical a pau me ka emi ʻana o ka mahana, me ka nānā ʻole i ke ʻano o ka mea, inā i hoʻolei ʻia ke alumini alumini a i ʻole ke alumini alumini deformed, ʻaʻohe mea inā he pauka metallurgy a i ʻole kahi mea i hoʻohui ʻia; ʻaʻohe mea e pili ana i ke kūlana o ka mea, inā paha i loko o ke kūlana hana a i ʻole ke kūlana wela; he kūʻokoʻa hoʻi ia i ke kaʻina hana hoʻomākaukau ingot, inā i ʻōwili ʻia e ka ingot a i ʻole e hoʻolei mau ʻia e ka heheʻe. ʻOlokaʻa a ʻōwili mau paha; ʻaʻohe pilina me ke kaʻina hana hoʻoheheʻe alumini, electrolysis, hōʻemi carbothermal, hoʻoiho kemika, ʻaʻohe brittleness haʻahaʻa haʻahaʻa; ʻAʻohe hilinaʻi i ka maʻemaʻe, inā he 99.50% ~ 99.79% o ke kaʻina alumini maʻemaʻe, a i ʻole 99.80% ~ 99.949% alumini maʻemaʻe kiʻekiʻe, 99.950% ~ 99.9959% ultra-purity alumini (Super Purity), 99.9960% ~ 99.9990% , >99.9990% ultra-high purity aluminika, etc. No haʻahaʻa wela brittleness.

ʻO ka mea hoihoi, ʻo nā metala māmā ʻelua ʻē aʻe—ka magnesium a me ka titanium—ʻaʻohe palupalu haʻahaʻa haʻahaʻa e like me ka alumini.
