Wahi a nā mea metala ʻokoʻa i loko o ka alumini, hiki ke hoʻokaʻawale ʻia ka alumini i 9 series. Ma lalo, e hoʻolauna mākou i ka7 moʻo alumini:

 
Nā hiʻohiʻona o7 moʻo aluminimea waiwai:

 
ʻO ka zinc, akā i kekahi manawa ua hoʻohui pū ʻia kahi mea liʻiliʻi o ka magnesium a me ke keleawe. Ma waena o lākou, ʻo ke alumini alumini paʻakikī paʻakikī he mea hoʻohui i loaʻa ka zinc, ke kēpau, ka magnesium, a me ke keleawe me ka paʻakikī kokoke i ke kila. ʻOi aku ka lohi o ka extrusion ma mua o ka 6 series alloy, a ʻoi aku ka maikaʻi o ka hana kuʻi. 7005 a7075ʻo ia nā māka kiʻekiʻe loa ma ka moʻo 7 a hiki ke hoʻoikaika ʻia e ka mālama wela.

Ka hoʻohana ʻana: ka mokulele (nā ʻāpana lawe ukana o ka mokulele, nā mea pae ʻāina), nā pōhaku, nā propellers, nā kaʻa aerospace.

Hoʻohana ʻia nā mea extruded 7005 e hana i nā hale welded e koi ana i ka ikaika kiʻekiʻe a me ka paʻakikī haʻihaʻi kiʻekiʻe, e like me nā pahu, nā koʻokoʻo, a me nā pahu no nā kaʻa lawe; ʻO nā mea hoʻololi wela nui a me nā ʻāpana ʻaʻole hiki ke hana i ka mālama fusion paʻa ma hope o ke kuʻi ʻana; Hiki ke hoʻohana ʻia no ka hana ʻana i nā mea haʻuki e like me nā racket tennis a me nā lāʻau softball.

 
7039 ʻO nā pahu pahu hau, nā mea haʻahaʻa haʻahaʻa a me nā pahu mālama, nā mea paʻi ahi, nā mea kaua, nā pā kaua, nā mea missile.

 
Hoʻohana ʻia ʻo 7049 no ka hana ʻana i nā ʻāpana me ka ikaika paʻa like me ka 7079-T6 alloy akā e koi ana i ke kūpaʻa kiʻekiʻe i ke koʻikoʻi o ka corrosion cracking, e like me nā mokulele a me nā ʻāpana missile - pae ʻāina hydraulic cylinders a me nā ʻāpana extruded. ʻO ka hana luhi o nā ʻāpana he like ia me ka 7075-T6 alloy, ʻoiai ke kiʻekiʻe iki ka paʻakikī.

 
7050hoʻohana nā mea hoʻolālā mokulele i nā papa mānoanoa waena, nā ʻāpana extruded, nā forging manuahi, a me nā forgings make. ʻO nā koi no nā alloys i ka hana ʻana o ia mau ʻāpana he kūpaʻa kiʻekiʻe i ka peel corrosion, stress corrosion cracking, fracture toughness, a me ke kūpaʻa luhi.

 
7072 air conditioner alumini pepa a me ka ʻili lahilahi; ʻO ka uhi ʻana o 2219, 3003, 3004, 5050, 5052, 5154, 6061, 7075, 7475, 7178 nā lau a me nā paipu.

 
Hoʻohana ʻia ʻo 7075 no ka hana ʻana i nā hale mokulele a me nā wā e hiki mai ana. Pono ia i nā ʻāpana hoʻolālā koʻikoʻi me ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion ikaika, a me ka hana ʻana i ka mold.

 
Hoʻohana ʻia ʻo 7175 no ka hana ʻana i nā hale kiʻekiʻe no ka mokulele. Loaʻa i nā mea T736 ka hana piha piha, me ka ikaika kiʻekiʻe, ke kū'ē i ka peeling corrosion a me ke koʻikoʻi o ka ʻinoʻino ʻana, ka haʻihaʻi paʻakikī, a me ka ikaika luhi.

7178 Nā Koina no ka Hana ʻana i nā Kaʻa Aerospace: Nā ʻāpana me ka ikaika o ka hoʻoulu ʻana.
ʻO ka fuselage 7475 i hanaʻia i ka alumini i uhiʻia a me nā paneli i uhiʻoleʻia, nā'ēheu'ēheu, nā kaola, a pēlā aku.

7A04 ʻili mokulele, nā ʻili, a me nā ʻāpana lawe ukana e like me nā kaola, nā papa, nā iwi ʻaoʻao, nā mea hoʻokele, etc.
