Aluminim vs. Hoʻolei iā Aluminum - nā mea likeʻole

1. Hōʻikeʻike

Kūlikeʻo Aluminim e like me kekahi o nā mea nui loa a hoʻohana nuiʻia i nā metala māmā.

ʻO konaʻano hoʻohālikelike o ka ikaika, Ke kū'ē neiʻo Corrosionion, aʻo ka laweʻana o ka thermal cenistictivity e hoʻolilo i ka mea i manaʻoʻia ma Aerospace, aitompetitive, kūkulu hoʻi, a me nā huahana waiwai.

Akā naʻe,, Ke hoʻoihoʻiaʻo Anuminim ma o nā hana kūʻaiʻana, ke hoʻololi nei i loko o kahiʻano hana kūikawā-chored aluminim-e hāʻawi i nā mea hana kūʻokoʻa.

I kēia mauʻano hoʻokūkū o kēia lā, ka hoʻomaopopoʻana i nā mea likeʻole ma waena o keʻano o ka alumini a me ka hoʻopiliʻana a me ka hoʻopiliʻana i ka aluminim no ka hoʻokōʻana i ka hana, Kālā, ao na mea hoʻohālikelike.

E hāʻawi kēiaʻatikala i kahi hohonu, ʻO ka hoʻohālikelikeʻana o ka dimensiontal o ka alumini.

Eʻimi mākou i kā lākou mau waiwai, Nā kaʻina hana hana, a me na noi noi,

ʻO nā mīkini hana likeʻole, Manaʻoʻia, a me nā mea hana e hana ai i nā koho waiwai e pili ana i ka hanaʻana i ka hanaʻana a me ka makemake.

2. He aha ka alumini?

Aluminum he māmā, ʻO ka mea iʻikeʻiaʻo Ductive i kahi pale kū'ē maikaʻi loa no kāna mau kūwaho maikaʻi loa a me ka kiʻekiʻe o ka nui.

Hoʻopili kēia metala i kahi hana pivototal i nā hana hana likeʻole, e komo pū ana, paulle, a kala iho, ʻO ka mea e pono ai, ʻO nā huahana kiʻekiʻe kiʻekiʻe.

• Waiwai:
  Hōʻikeʻo Alminimum, Ke kūpono nei i nā mea hana wela a me nā mea uila uila.
  Eia hou, Alumini alloys e like me 6061 and 7075 Hāʻawi i nāʻano hana hana Tailored e hana i nā noi kiko'ī.

3. He aha ka mea a ka cart aluminim?

E pili anaʻo ia i ka alumini e pili ana i ka alumini i hanaʻia ma o kahi kaʻina kūʻai, kahi i nininiʻia aiʻo Molten Aluminim i loko o kahi mū a hoʻopaʻaʻia i loko o kahiʻano kiko'ī.

ʻAʻole like me ka hana aluminim, e hoʻoihoʻia ma o ka holoʻana, hānehi, a iʻole ke kalaʻia, Ua hana pololeiʻiaʻo ia i ka aluminamum mai kona wahi wai.

ʻO kēiaʻano hana e hana ai i nā mea hana e hana ai i nā geomex paʻakikī a me nā'āpana likeʻole-like-like-like-like-like-like-like me ka mīkini liʻiliʻi.

Ma muli o kānaʻano, E hoʻokani i ka alumumimum i kahi kūlana koʻikoʻi i nāʻoihana e noi i ka māmā, piha, a me nā'āpana likeʻole.

Mai nā mea hoʻokele mīkini i nā hoʻonohonohoʻana o Aerospace a me nā mea kūʻai aku, E hana anaʻo ia i kahi hoʻololi a Aluminim i kahi koho i makemakeʻia i nā hana hou.

Ke kaʻina hana hana o ka laweʻana i ka alumini

ʻO ke kaʻina hana e hoʻopili nui ai i nā micsstructure alumini, Nā Pīkuhi Propertinies, a hoʻopauʻia.

Eʻae nāʻenehana caspniquers e hāʻawi i nā mea hana e kaulike ai i nā mea e like me ke kumukūʻai, 'Clelo pololei, a me ka wikiwiki. Ma lalo o nā hana e hoʻohana nuiʻia ai nā hana:

Hoolei Make

• Make buring pili i ka hoʻopiliʻana i ka molten aluminum (make) Ma lalo o ke kaomi kiʻekiʻe.
• He kūpono kēia kaʻina hana no ka hana nui, hāʻawi aku i ka pololei o ka dimensional kūpono a me ka hoʻopauʻana.
• Ua hoʻohana nuiʻia nā mea make alum aitompetitive, AerERPPACE, a me nā mea hoʻohana uila.
• Hoʻohana pinepineʻia nā alloys maʻamau: A380, A383, ADC12

  

Sand cread

• ʻO Sand Canding e pili ana i ka hoʻokumuʻana i kahi mold mai ka nui o ke oli, Ua nininiʻiaʻo Molten Aluminim.
• He kumu kūpono kūpono ia e kūpono ai no nā'āpana nui a me nā'āpana paʻakikī akā e hana i kahi alaloa e hoʻopau ai.
• Ua hoʻohana pinepineʻiaʻo Sand Canding Nā mīkini mīkini, Nā Hale Hōʻikeʻike, a me nā meaʻona a me nā meaʻona hana.
• Hoʻohana pinepineʻia nā alloys maʻamau: A356, 319, 535

Ke hoʻomau mau nei (ʻO ke kāheaʻana)

• Ua nininiʻiaʻo Molten Aluminim i loko o kahi molū hou e hoʻohana ai i ka gravity ma mua o ke kaomi.
• ʻO nā hopena hana i ka ikaika, ʻO nā'āpana denser i hoʻohālikelikeʻia i ke kauʻana o ka sand.
• Hoʻohana pinepineʻiaʻo Moll Canding Nā huila kaʻa, Nā'āpana Hydraulic, a me nā'āpana aerospace.
• Hoʻohana pinepineʻia nā alloys maʻamau: 356, 319

Hoʻolei kālā (Nalowale-wax casting)

• ʻO kahi hiʻohiʻona wax o ka'āpana i hoʻopaʻaʻia me ka cemic, ke hanaʻana i kahi mold. Ua holoiʻia ka wax, a ua nininiʻiaʻo Molten Alminim i loko o ka lua.
• Ke hoʻokō nei kēiaʻano nā kiko'ī kiʻekiʻe a me nā kiko'ī, Ke kūpono nei ia no ka paʻakikī a me nā'āpana olakino.
• Hoʻohana pinepineʻia nā alloys maʻamau: A356, A357

Nā waiwai o kā kalamini

ʻO ka hanaʻana o ke kaʻina hana i ka hana a Alters aluminum a me nā mea waiwai, hana ia mai ka hana a puni. Eia nā hiʻohiʻona nui o ka hopuʻana iā Aluminim:

ʻO keʻano a me ka ikaika

• Ma muli o ke kaʻina hana a me ke kaʻina hana, Hōʻike pinepineʻo ia iā Aluminamum i kahi ʻO ka hoʻolālā grainser carin ua hoʻohālikelikeʻia e hana i ka alumini.
• Hiki i kēiaʻano ke alakaʻi i ka ikaika haʻahaʻa haʻahaʻa a me ka lōʻihi, akā, hiki i nā mea āpau a me nā hana wela e hiki ai ke hoʻomaikaʻi i ka hana.
• Hiki i kekahi mau keiki alumini e hiki ke hoʻokō i nā ikaika o ka 200-300 mPA, He kūpono no nā noi pili.

Ke kū'ē neiʻo Corrosionion

• Hana kūlohelohe aluminam Toode Tooner, Hāʻawi i ka paleʻana o ka corrosion maikaʻi.
• ʻO kekahi mau mea kūʻai akuʻo Aluminum, e like me A356 a 319, i kohoʻia no ka hoʻohuliʻana i ka paleʻana i nā wahi hana.

Hoʻopau a me ke aniani

• 'Ōlelo ka hopena o ka sland aluminim hilinaʻiʻia i ke ala kūʻai. ʻO ka mea make e hānai ana i nā mea e hana ai i nā papahele (Ra 1.6-3.2 μm), ʻOiai ke kauʻana o ka sanding i nā hualoaʻa ma nā palapala rougher (RA 6.3-12.5 μM).
• Hoʻololi ka machnicability; Hiki i kekahi mau hale kūʻai ke koi hou i nā hana hou e like me CNC machining a iʻole ka polish e hoʻokō ai i nā mea paʻa paʻa.

ʻO keʻano o ke kālepa a me ke kālepa

• Mālama i nā mea aluminlum ke alakaʻiʻana i ka thermal (~ 12 120-160 w / m · c · k), Ke kūpono kūpono no nā mea kūʻai aku wela a me nā noi noi.
• ʻOiai ke haʻahaʻa nei ka laweʻana i ka uila ma mua o ka alumini maʻamau, Ua hoʻohana nuiʻiaʻo ia i ka alunimum i nā mea uila a me nā mea wela wela.

ʻO nā mea maʻamau a me nā noi a me ko lākou noi

4. Aluminim vs. Hūnā.

Ua pāʻaniʻo Alumini i kahi hana koʻikoʻi i ka hana houʻana, hāʻawi ka ikaika māmā, Ke kū'ē neiʻo Corrosionion, a me ka hana ino loa.

Akā naʻe,, I ka wā e loiloi ai hana aluminum (Hoʻokumuʻia ma o ka holoʻana, hānehi, a iʻole ke kalaʻia) kūwaho hūnā. (ua hanaʻia ma o nā hana casting),

He mea nui ia e hoʻomaopopo i ko lākou mauʻokoʻa i loko Nā Pīkuhi Propertinies, moloka, markinpalibility, Ke kū'ē neiʻo Corrosionion, a me na noi noi.

Ke hana nei i ka koho kūpono ma waena o kēia mauʻanoʻelua o ka alumini e hilinaʻi nei Hoʻolālā paʻakikī, Kālā, Nā pono ikaika, a me ka hana mana.

Hōʻike kēia'āpana i nāʻokoʻa, ka hoʻolakoʻana i kahi hoʻohālikelike hohonu i loko o ke kōkuaʻana i nā meaʻenehana, Manaʻoʻia, Aʻo nā mea hana hana e hoʻoholo i nā hoʻoholo.

Nā Pīkuhi Propertinies: Ikaika, Kumaikalua, a me kaʻehaʻeha

ʻO ka hana mechanical kahi mea like me ka like like ma waena o ka alumini a me nā aluminim. E kū mai nāʻokoʻa ʻO ke kaʻina hana a me ka hopena o keʻano grain.

Tissile a hāʻawi i ka ikaika

• Uaʻoi aku ka nui o nā mea hana a Alminim Ma muli o ka hana paʻakikī, ka hoʻopiliʻana i keʻano grain, a me nā mea liʻiliʻi he nui.
