Loaʻa i kēlā me kēia huila nā pākēneka kūikawā o nā mea hoʻohui e hāʻawi i ke kumu alumini i kekahi mau ʻano pono. ka ikaika kiʻekiʻe, e like me ke keleawe, ka magnesium, a me ka manganese e hoʻonui nui i ka ikaika o nā alumini alumini. , hao, zinc, titanium, a me nā mea'ē aʻe), akā, hāʻawi waleʻia kēia mau mea i ka hoʻomanawanui ma ka noi a ka mea kūʻai. /in3) .2024 alumini he mea maʻalahi loa i ka mīkini a he machinability maikaʻi, hiki ke ʻoki ʻia a hoʻokuʻu ʻia ke koi ʻia.
E like me ka mea i ʻōlelo ʻia, ʻoi aku ka maʻalahi o nā alumini alumini 2024 ma mua o ka hapa nui o nā alumini alumini ʻē aʻe. Hoʻopili nā mea hana i kēia ma ka uhi ʻana i kēia mau mea hiki ke hoʻopili ʻia me kahi papa o ka corrosion-resistant metal (i kapa ʻia ʻo "galvanizing" a i ʻole "cladding"). alumini hoʻomaʻemaʻe a i ʻole kekahi mea ʻē aʻe, a kaulana loa i nā ʻāpana metala ʻaʻahu, kahi e hiki ai ke hoʻopili ʻia ka hui puʻupaʻa ma waena o nā ʻāpana pale. ʻO nā honua ʻelua no nā ʻāpana palupalu palupalu e like me 2024. ʻO kēia hoʻomohala ʻana i ka 2024 aluminika i mea pono loa no ka mea hiki ke hoʻokō ʻia kona ikaika ma kahi e hoʻohaʻahaʻa maʻamau ai nā alloys ʻole.
Hiki ke hoʻoikaika ʻia kekahi mau alumini alumini, e like me ka 2xxx, 6xxx, a me 7xxx me ka hoʻohana ʻana i kahi kaʻina i kapa ʻia ʻo ka mālama wela. hoʻopaʻa i nā mea e hoʻopaʻa ai i nā mea. Ua kapa ʻia kēia ʻanuʻu he "solution heat treatment". ʻO Al2Cu). Hoʻonui kēia mau pūhui i ka ikaika holoʻokoʻa o ka alloy ma o ka launa pū ʻana me ka microstructure aluminika, kahi hana i kapa ʻia ʻo "ka ʻelemakule." e like me 2024-T4, 2024-T59, 2024-T6, a me nā mea ʻē aʻe, e pili ana i ka hana ʻana o kēia mau ʻanuʻu.
ʻO nā ʻano ikaika maikaʻi loa o ka 2024 alumini ʻaʻole wale mai kona haku ʻana, akā mai kāna kaʻina hana wela. ), a ʻoiai ʻo lākou ka mea like ʻole, loaʻa iā lākou a pau ko lākou mau waiwai ponoʻī. he 2024-T42 wela, he “4″ e hōʻike ana i ka alloy he hopena wela i mālama ʻia a ʻelemakule maoli, akā ʻo ka "2" e hōʻike ana he pono e mālama ʻia ka metala e ka mea kūʻai aku. Hiki ke huikau ka ʻōnaehana, no laila ma kēia ʻatikala mākou e hōʻike wale i nā waiwai ikaika no kahi alumini 2024-T4 maʻamau.
Aia kekahi mau waiwai mechanical e hiki ke hoʻohana no ka wehewehe ʻana i nā alumini alumini. ka manaʻo e pili ana i ka machinability, ka ikaika a me ka hoʻohana pono ʻana o ka mea a ua hōʻuluʻulu ʻia ma ka Papa 1 ma lalo.
ʻO ka ikaika a me ka ikaika hope loa, ʻo ia nā koʻikoʻi kiʻekiʻe loa e hiki ai ke hoʻololi mau ʻole a me ka hoʻololi mau ʻana o nā mea hoʻoheheʻe alloy, kēlā me kēia. Hoʻohana ʻia i nā noi static kahi e hiki ʻole ai ka deformation mau loa, e like me nā hale a i ʻole nā mea hana palekana.2024 alumini he mea hoʻohiwahiwa hope loa a hāʻawi i nā ikaika o 469 MPa (68,000 psi) a me 324 MPa (47,000 psi), e ʻoluʻolu no ka ikaika kiʻekiʻe. nā mea hana e like me nā paipu alumini.
ʻO ka hope, ʻo ka modulus elastic a me ka modulus shear he mau ʻāpana e hōʻike ana i ke ʻano o ka "elastic" o kahi mea i hāʻawi ʻia. (10,600 ksi) a me ka modulus shear o 28 GPa (4,060 ksi), ʻoi aku ka kiʻekiʻe ma mua o nā huila mokulele ikaika kiʻekiʻe e like me 7075 aluminika.
ʻO ke ʻano 2024 alumini he machinability maikaʻi loa, hiki ke hana maikaʻi, ikaika kiʻekiʻe, a hiki ke hoʻopaʻa ʻia e pale aku i ka corrosion, e lilo ia i koho maikaʻi loa no nā mokulele a me nā noi kaʻa.
