He aha ka 2024 Aluminum Alloy?

Na Waiwai Kemika o2024 Aluminum

Loaʻa i kēlā me kēia alloy kahi pākēneka kikoʻī o nā mea alloying e hoʻopiha i ka alumini kumu me kekahi mau ʻano pono. I ka 2024 alumini alumini, ʻo kēia mau pākēneka element e like me lalo o ka pepa ʻikepili. ʻO ia ke kumu i ʻike ʻia ai ka aluminika 2024 no kona ikaika kiʻekiʻe no ka mea ʻoi aku ka nui o ke keleawe, ka magnesium, a me ka manganese i ka ikaika o nā alumini alumini.

ʻOi aku ka maʻalahi o ka alumini alumini Bare 2024 ma mua o ka hapa nui o nā alumini alumini ʻē aʻe, no laila ua hoʻoponopono nā mea hana i kēia pilikia ma ka uhi ʻana i kēia mau mea hiki ke hoʻopaʻa ʻia me kahi papa o ka metala kūpaʻa.

Hoʻomaʻamaʻa wela no ka hoʻonui ʻana i ka ikaika

Loaʻa ka ʻano 2024 alumini i kona mau ʻano ikaika maikaʻi ʻaʻole wale mai ka haku mele wale nō, akā mai ke kaʻina hana e mālama ʻia ai ka wela. Nui nā kaʻina hana like ʻole, a i ʻole "tempers" o ka alumini (i hāʻawi ʻia i ka mea hoʻolālā -Tx, kahi x he helu lōʻihi hoʻokahi a ʻelima), aia nā mea āpau i ko lākou mau ʻano ʻokoʻa ʻoiai ʻo ia ka alloy like.

Na Waiwai Mechanical

No kahi huila e like me 2024 aluminika, ʻo kekahi mau ana koʻikoʻi ka ikaika hope, ka ikaika hoʻohua, ka ikaika shear, ka ikaika luhi, a me ka modulus o ka elasticity a me ka modulus shear. Hāʻawi kēia mau waiwai i ka manaʻo e pili ana i ka hiki ke hana, ka ikaika, a me ka hoʻohana ʻana i kahi mea, a ua hōʻuluʻulu ʻia ma lalo o ka pepa ʻikepili.

Na Waiwai Mechanical Metric Pelekania
ʻO ka ikaika ʻoi loa 469 MPa 68000 psi
ʻO ka ikaika o ka tensile yield 324 MPa 47000 psi
Ka ikaika shear 283 MPa 41000 psi
Ka ikaika luhi 138 MPa 20000 psi
Modulus o Elasticity 73.1 GPa 10600 ksi
ʻO ka hoʻoheheʻe ʻana 28 GPa 4060 ksi

Nā noi o 2024 Aluminum

ʻO ke ʻano 2024 alumini he machinability maikaʻi loa, hiki ke hana maikaʻi, ikaika kiʻekiʻe, a hiki ke hana ʻia e pale aku i ka corrosion me ka pale ʻana, e lilo ia i koho maikaʻi loa no nā mokulele a me nā noi kaʻa. Hoʻohana ʻia ka alumini 2024 ma nā ʻoihana he nui, akā ʻo kekahi mau noi maʻamau no kēia alloy maikaʻi loa penei:
