1. Heʻuʻuku loa ka nui o ka alumini, 2.7g / cm wale nō. ʻOiai he palupalu, hiki ke hana i nā ʻano like ʻolealumini alumini, e like me ka alumini paʻakikī, ka alumini paʻakikī ultra, ka alumini rust proof, ka alumini hoʻolei, a me nā mea'ē aʻe. Eia kekahi, hoʻohana pū kekahi i nā rockets space, spacecraft, a me nā satelite artificial i ka nui o ka alumini a me kāna mau alloys. No ka laʻana, ua haku ʻia kahi mokulele supersonic ma kahi o 70% aluminika a me kāna mau alloys. Hoʻohana nui ʻia ka alumini i ka hana moku, me kahi moku kaʻa nui e ʻai pinepine ai i mau tausani mau tona alumini.

2. ʻO ka conductivity o ka alumini ka lua wale nō i ke kālā a me ke keleawe. ʻOiai ʻo kona conductivity he 2/3 wale nō o ke keleawe, ʻo kona density he 1/3 wale nō o ke keleawe. No laila, i ka lawe ʻana i ka nui like o ka uila, ʻo ka maikaʻi o ka uea alumini he hapalua wale nō o ka uea keleawe. ʻO ke kiʻi oxide ma ka ʻili o ka alumini ʻaʻole wale ka hiki ke pale aku i ka corrosion, akā loaʻa kekahi ʻano o ka insulation, no laila he nui nā noi o ka alumini i ka ʻoihana hana uila, uea a me nā ʻoihana kelepona, a me nā ʻoihana uila.

 
3. ʻO ka alumini ka mea hoʻokele maikaʻi o ka wela, me ka conductivity thermal ʻekolu mau manawa ma mua o ka hao. I ka ʻoihana, hiki ke hoʻohana ʻia ka alumini no ka hana ʻana i nā mea hoʻololi wela, nā mea hoʻopau wela, a me nā mea kuke.

 
4. He ductility maikaʻi ka alumini (ʻelua wale nō i ke gula a me ke kālā), a hiki ke hana ʻia i ka alumini foil ʻoi aku ka lahilahi ma mua o 0.01mm ma nā mahana ma waena o 100 ℃ a me 150 ℃. Hoʻohana nui ʻia kēia mau pepa alumini no ka hoʻopili ʻana i nā cigakeke, nā lole, a me nā mea ʻē aʻe.

 
5. ʻAʻole hiki ke hoʻopili maʻalahi ka ʻili o ka alumini ma muli o kāna kiʻi ʻoniʻoni pale oxide, a hoʻohana pinepine ʻia e hana i nā reactors kemika, nā lāʻau lapaʻau, nā lako refrigeration, nā mea hoʻomaʻemaʻe ʻaila, nā pipelines aila a me ke kinoea, etc.

 
6. He ʻeleʻele keʻokeʻo keʻokeʻo kālā ka pauda alumini (ʻo ka mea maʻamau ka waihoʻoluʻu o nā metala i loko o ka pauda he ʻeleʻele ka hapa nui), a hoʻohana mau ʻia ma ke ʻano he uhi, ʻike mau ʻia ʻo ka pauda kālā a i ʻole ka pena kala, no ka pale ʻana i nā huahana hao mai ka ʻinoʻino a hoʻonui i ko lākou helehelena.

 
7. Hiki i ka alumini ke hoʻokuʻu i ka nui o ka wela a me ke kukui ʻālohilohi ke puhi ʻia i loko o ka oxygen, a hoʻohana mau ʻia e hana i nā mea pahū, e like me nā mea pahū alumini ammonium (i hana ʻia me ka hui ʻana o ka ammonium nitrate, ka pauka lanahu, ka pauka alumini, ʻeleʻele uahi, a me nā mea ola ʻē aʻe e hiki ke puhi ʻia), hui pū ʻia (e like me nā pōkā a me nā pūpū i hana ʻia me ka alumini thermite hiki ke hoʻohana ʻia no ka hoʻouka ʻana i nā pahuhopu paʻakikī a i ʻole. nā pahu, nā pūkuniahi, a me nā mea ʻē aʻe), a me nā hui kukui (e like me ka barium nitrate 68%, ka pauka aluminika 28%, a me ke kāpili pepeke 4%).

 
8. Hoʻohana mau ʻia ka thermite alumini no ka hoʻoheheʻe ʻana i nā metala refractory a me ke kuʻi ʻana i nā ala hao. Hoʻohana pū ʻia ka alumini ma ke ʻano he deoxidizer i ke kaʻina hana kila. ʻO ka pauka alumini, ka graphite, ka titanium dioxide (a i ʻole nā ​​​​mea hoʻoheheʻe metala kiʻekiʻe ʻē aʻe) i hui like ʻia i kekahi ratio a uhi ʻia ma ka metala. Ma hope o ka calcination kiʻekiʻe, hana ʻia nā seramika metala kūpaʻa kiʻekiʻe, he mau noi koʻikoʻi i ka ʻenehana rocket a me ka missile.

 
9. He maika'i ka hana no'ono'o māmā o ka pā alumini, e hō'ike ana i nā kukuna ultraviolet i'oi aku ka ikaika ma mua o ke kālā. ʻOi aku ka maʻemaʻe o ka alumini, ʻoi aku ka maikaʻi o kona hiki ke noʻonoʻo. No laila, hoʻohana maʻamau ia e hana i nā mea hoʻonaninani kiʻekiʻe, e like me nā mea hoʻoheheʻe i ka lā.

10. He mau mea kani ka alumini a me nā hopena leo maikaʻi, no laila, ua hana ʻia nā kaupaku ma nā keʻena hoʻolaha a me nā hale nui hou i ka alumini.

 
11. Ke pale wela haʻahaʻa: Ua hoʻonui ka Aluminum i ka ikaika me ka ʻole o ka brittleness i nā haʻahaʻa haʻahaʻa, e lilo ia i mea kūpono no nā mea haʻahaʻa haʻahaʻa e like me nā pahu hau, nā pahu hau, nā kaʻa hau Antarctic, a me nā mea hana hydrogen oxide.

 
12. He oxide amphoteric ia
