ʻepekema kaulana: ka laula hehee o na alumini alumini

Nānā nui

ʻO ka alumini ka metala kupaianaha, ʻike ʻia no kona ʻano maʻalahi, hiki ke hana, a me nā waiwai māmā. Me kahi helu heheʻe i lawa ke kiʻekiʻe e hoʻohana i ka nui o nā noi, ʻAʻole ia he mea kupanaha ʻo kēia ʻāpana ke kolu o ka nui loa o ka ʻōpala o ka Honua a me ka metala non-ferrous i hoʻohana nui ʻia ma hope o ke kila.. Ma kēia moʻomanaʻo moʻomanaʻo, e ʻimi mākou i ka helu heheʻe o ka alumini, kona mau hopena no nā alumini alumini like ʻole, nā mea e pili ana i kēia waiwai koʻikoʻi, kona mau noi, a pehea e hoʻohālikelike ai me nā metala ʻē aʻe.

Ka Papa Heehee o Aluminum Alloys

ʻO ka helu hoʻoheheʻe o ka alumini kahi waiwai nui e pili ana i kona hoʻohana ʻana i nā ʻoihana like ʻole. ʻO ka helu heheʻe o ka alumini maʻemaʻe he 660.32°C (1220.58°F). Eia naʻe, ke hoʻohui ʻia nā mea ʻē aʻe e hana i nā alumini alumini, hiki ke loli ke kiko hehee. ʻO kēia ka papa helu heheʻe o nā pūʻulu ʻewalu o nā alumini alumini forged:

moʻo Lae hehee (°C) Lae hehee (°F)
1000 Aluminum moʻo 643 – 660 1190 – 1220
2000 Hui Aluminum moʻo 502 – 670 935 – 1240
3000 Hui Aluminum moʻo 629 – 655 1170 – 1210
4000 Hui Aluminum moʻo 532 – 632 990 – 1170
5000 Hui Aluminum moʻo 568 – 657 1060 – 1220
6000 Hui Aluminum moʻo 554 – 655 1030 – 1210
7000 Hui Aluminum moʻo 476 – 657 889 – 1220

Nānā: mai ka ʻikepili mai Matweb.

Hōʻike kēia mau pae i ka hoʻohui ʻana o nā mea hoʻohui i hiki ke hoʻololi nui i ka helu heheʻe e kūpono i nā noi kikoʻī.

Lae hehee o na Aluminum Aluminum ma'amau

Loaʻa i nā pūʻulu alumini alumini hoʻoheheʻe nui ʻewalu i hoʻohana nui ʻia. Koho ka papa ma lalo nei i kekahi o ia mau mea e hōʻike i ka pae helu heheʻe:

Alloy Model moʻo Lae hehee (°C) Lae hehee (°F)

Nā mea e pili ana i ka lae hehee o ka alumini

Hiki i kekahi mau mea ke hoʻololi i ka helu heheʻe o ka alumini a me kāna mau ala:

  • Nā Elements Alloying: ʻO ka loaʻa ʻana o nā mea hoʻohui e like me ke keleawe, magnesium, silika, a hiki i ka zinc ke hoʻokiʻekiʻe a hoʻohaʻahaʻa paha i ka helu heheʻe, ma muli o kā lākou pilina me ka alumini.
  • haumia: Hiki ke ho'opō'ino i ka helu hehe'e. ʻo kahi laʻana, hao, he mea haumia, hiki ke hoemi i ka helu hehee.
  • Moʻolelo Thermal: ʻO ka moʻolelo wela o ka alumini, me nā hoʻomaʻamaʻa wela mua a i ʻole ka hana ʻana, hiki ke hoʻomaʻemaʻe i ke ʻano o ka palaoa a pili i ka helu heheʻe.
  • Nā Hana Hana: Nā ʻenehana hana like ʻole, e like me ka hoʻopaʻa wikiwiki ʻana a i ʻole ka pauka metallurgy, hiki ke alakaʻi i nā microstructure non-equilibrium me nā helu heheʻe like ʻole.

Nā noi o ke kiʻekiʻe heheʻe o ka Aluminum

ʻO ka helu hoʻoheheʻe kiʻekiʻe o ka alumini a me kāna mau mea hoʻohui e kūpono iā lākou no ka nui o nā noi wela kiʻekiʻe:

  • ʻO ka wiliwili a me ka Brazing: ʻO ka wahi hoʻoheheʻe kiʻekiʻe o Aluminum e hiki ai ke hoʻopaʻa ikaika a me nā ʻenehana brazing, he mea nui i ka hana ʻana i nā hale paʻakikī a me nā ʻāpana.
  • Mea Hoʻololi Wela: ʻO ka helu hoʻoheheʻe kiʻekiʻe o kekahi mau alumini alumini e kūpono iā lākou no ka hoʻohana ʻana i nā mea hoʻololi wela, kahi e hiki ai iā lākou ke pale i nā mahana hana kiʻekiʻe me ka hoʻoheheʻe ʻole.
  • Mea kuke: He mea maikaʻi nō hoʻi ka helu heheʻe kiʻekiʻe o Aluminum i ka hana ʻana i nā mea kuke, e hōʻoia ana e hiki i nā ipu hao a me nā pā ke mālama i nā mahana kuke kiʻekiʻe me ka pilikia ʻole o ka heheʻe.

Pehea ka hoʻohālikelike ʻana o ka lae heheʻe alumini me nā metala ʻē aʻe

Ke hoʻohālikelike ʻia me nā metala ʻē aʻe, ʻaʻole kiʻekiʻe ka helu heheʻe o ka alumini. Eia ka hoʻohālikelike o nā helu heheʻe o ka alumini me kekahi mau metala maʻamau:

Metala Lae hehee (°C) Lae hehee (°F)
Aluminum 660.32 1220.58
keleawe 1085 1981
Hao 1538 2800
Zinc 419 776
kila 1370 – 1520 (ʻokoʻa) 2502 – 2760 (ʻokoʻa)

Hōʻike kēia hoʻohālikelike ʻoiai he haʻahaʻa ka helu heheʻe o ka alumini ma mua o nā metala e like me ka hao a me ke kila, ʻoi aku ka kiʻekiʻe ma mua o ka zinc a me nā metala ʻē aʻe he nui. Hoʻonoho kēia i ka alumini i kahi kūlana kūpono no nā noi e pono ai ke kaulike ma waena o ke kūpaʻa wela kiʻekiʻe a me ka hana.

I ka hopena, ʻO ka helu hoʻoheheʻe o ka alumini he waiwai koʻikoʻi e pili ana i kona hoʻohana ʻana i nā ʻoihana like ʻole. ʻO ka hoʻomaopopo ʻana i nā mea e pili ana i kēia waiwai a me ke ʻano o ka hoʻohālikelike ʻana i nā metala ʻē aʻe he mea nui ia no ke koho ʻana i nā mea waiwai a me ka hoʻoponopono ʻana i ka hana.. Ka helu heheʻe kiʻekiʻe o Aluminum, hui pu me kona mau waiwai pono e ae, hana ia i mea maʻalahi no ka nui o nā noi.
