Wehe i na Pohihihi: ʻO nā ʻano like ʻole o nā Aluminum Alloys

ʻO nā alumini alumini kekahi o nā mea maʻalahi loa, hoʻohana ʻia i nā mea āpau mai ka ʻenekinia aerospace a i nā lako kīhini. ʻAʻole kumu ʻole ko lākou kaulana; Hāʻawi kēia mau mea hoʻohui i kahi kaulike kupaianaha o ka ikaika, kaumaha, a me ka pale ʻana i ka corrosion i hiki ke hoʻohālikelike i nā mea liʻiliʻi. Eia naʻe, hoʻokahi mea hoihoi e huikau pinepine i nā mea hou: aia nā ʻokoʻa liʻiliʻi ma waena o nā māka alumini alumini like ʻole(Papa density o na alumini alumini), a ke ʻimi nei kēia blog i nā mea e pili ana i kēia mau ʻokoʻa paʻa.

pepa alumini & pā

Aluminum alloy moʻo a me kona typical mākau

ʻO nā alumini alumini nā mea i haku ʻia me ka alumini (Al) a me nā mea hoʻohui like ʻole (e like me ke keleawe, magnesium, silika, zinc, etc.) e hoʻonui ai i kā lākou mau waiwai mechanical a me ka hoʻohana ʻana no nā noi like ʻole. E like me nā mea hoʻohui nui, hiki ke maheleia i 8 moʻo , Loaʻa i kēlā me kēia moʻo kekahi mau māka hao.

Aia ma lalo kahi papaʻaina e hōʻike maʻalahi i ka moʻo alumini alumini nui a me kekahi mau māka i loko o kēlā me kēia moʻo, e hōʻike ana i kā lākou mau hiʻohiʻona mua a me nā noi maʻamau.

Ka hopena o nā mea hoʻohuihui i ka paʻa o nā alumini alumini

Hoʻoholo nui ʻia ka density o nā alumini alumini e kona ʻano. ʻO ka nui o ka alumini maʻemaʻe ma kahi o 2.7 g/cm3 a i ʻole 0.098 lb/in3 , akā, hiki i ka hoʻohui ʻana i nā mea hoʻohuihui ke hoʻololi i kēia waiwai. ʻo kahi laʻana, hoʻohui keleawe (ʻoi aku ka paʻakikī ma mua o ka alumini) e hana i nā mea like 2024 a i ʻole 7075 hiki ke hoʻonui i ka nui o ka mea i loaʻa. ʻO ka ʻokoʻa, ʻoi aku ka liʻiliʻi o ka silikona a ke hoʻohana ʻia i nā alapili e like me 4043 a i ʻole 4032, e hoemi ana i ka manoanoa holookoa.

Papa o ka Alloying Elements a me ko lakou hopena i ka Density

Mea hoʻohuihui ʻO ka mānoanoa (g/cm³) Ka hopena ma ka Aluminum Alloy Density
Aluminum (Al) 2.70 Kumukumu
keleawe (Cu) 8.96 Hoʻonui i ka nui
Silika (A) 2.33 Hoʻemi i ka nui
Magnesium (ʻO Mg) 1.74 Hoʻemi i ka nui
Zinc (ʻO Zn) 7.14 Hoʻonui i ka nui
Manganese (ʻO Mn) 7.43 Hoʻonui i ka nui

ʻO ka palapala hoʻopaʻapaʻa alumini alumini maʻamau

Aia ma lalo kahi pakuhi maʻamau o nā density no kekahi mau alumini alumini maʻamau, No ka ʻike hou aku e pili ana i ke kiko kikoʻī o nā alumini alumini, e kipa mai ʻO ka mānoanoa o 1000-8000 Hui Aluminum moʻo ʻO kēia mau kumukūʻai ma kahi kokoke a hiki ke hoʻololi ʻia ma muli o ke ʻano kikoʻī a me ka hana ʻana o ka alloy.

Mai ka papa i luna, hiki iā mākou ke ʻike maʻalahi i kēlā:

  • 2000 He nui ka nui o ke keleawe i loko o nā huila moʻo a ʻoi aku ka nui o ka nui ma muli o ke kiʻekiʻe kiʻekiʻe o ke keleawe..
  • He ʻokoʻa, 6000 ʻO nā huila pūʻulu i loaʻa ke silikoni a me ka magnesium e hōʻike maʻamau i nā haʻahaʻa haʻahaʻa.
  • ʻIke ʻia no kona ikaika kiʻekiʻe, 7075 he nui ka zinc, magnesium a me ke keleawe. ʻO ke kiʻekiʻe kiʻekiʻe o 7075 i hoʻohālikelike ʻia me nā mea hao 1050 a 6061 hiki ke hoʻopili ʻia i ka loaʻa ʻana o kēia mau mea kaumaha.
  • 5083 huikau is commonly used in marine applications and has a lower density than other alloys due to its higher magnesium content and lower content of heavier alloying elements.

Ka hopena o nā kumu ʻē aʻe

Ma waho aʻe o nā mea hoʻohui, ʻO ka nui o nā alumini alumini e hoʻopili ʻia e nā kumu ʻē aʻe:

  • Mahana: Aluminum, e like me nā metala ʻē aʻe, e hoʻonui i ka wā i wela ai a e ʻaelike i ka wā i maʻalili. Hoʻopili kēia hoʻonui a me ka hoʻohaʻahaʻa wela i ka leo o ka alloy, ma laila e hoʻololi ai i kona mānoanoa.
  • ʻenehana hana: ʻO ke ʻano o ka hana ʻana o ka aluminika e pili pū i kona ʻano. ʻo kahi laʻana, ʻO ka wikiwiki o ka hoʻoilo ma hope o ka hoʻolei ʻana hiki ke alakaʻi i nā microstructure ʻokoʻa, ka mea e pili ana i ka nui.
  • haumia: ʻO ke alo o nā haumia, ʻoiai ma nā mea liʻiliʻi, hiki ke hoʻololi i ka mānoanoa o ka huila. ʻO kahi huila kiʻekiʻe me ka haʻahaʻa haʻahaʻa haumia e loaʻa i kahi paʻa paʻa.

ʻAʻole waiwai paʻa ka paʻa o nā alumini alumini akā ʻokoʻa ma muli o nā mea hoʻohui, kaʻina hana a me ka maʻiʻo haumia. Ma ka hoʻolālā a me nā noi ʻenekinia kahi e hana nui ai ke kaumaha, pono e noʻonoʻo ʻia kēia mau hoʻololi. Ma ka hoʻomaopopo ʻana i nā mea e pili ana i ka paʻa, Hiki i nā ʻenekini ke koho i ka alumini alumini kūpono e hoʻokō i kāna mau koi a me ke kaumaha.
