Ke kāʻili neiʻo Aluminim i nā koho maikaʻi loa no nā'āpana māmā?
Aole mau. No nā'ōnaehana maʻalahi, Hiki ke lanakila a lanakila paha, a no nā pā kiʻekiʻe kiʻekiʻe a iʻole nā ukana wela, Hiki ke makemakeʻiaʻo Steel a iʻole Titanium.
ʻO ka paleʻana i ke aniani māmā, kumukūʻai a me nā mea hana no nā noi he nui.
Pehea e hoʻoleiʻia ai nā'āpana alumini?
ʻO ka mahalo maikaʻi i ka maʻi pale pale. No ka mare a iʻole chrlode-waiwai waiwai, E koho i nā alloys kūpono, Nā pāpale (aodize, pehi), a hoʻolālā e pale aku ai i nā crevices a iʻole galvanic camvalin.
Hiki ke hoʻolei i ka aluminalum i hoʻohana no nā'āpana koʻikoʻi-scitical?
ʻAe - hoʻolako i nā mea i hāʻawiʻia i nā mea e hōʻemi i nā poosity (ʻO ka panaʻana, Hip inā pono) aʻo nā hoʻolālā e hōʻemi ai ka ho'ēmiʻana o nā pilikia koʻikoʻi.
Hiki ke hoʻolei i ka alumini e hoʻololi i ka hao hao i nā noi a pau?
ʻAʻole makemakeʻia ka hao hao no ka lole kiʻekiʻe, nā noi kiʻekiʻe (E.g., ʻO nā mea kaumaha-koʻikoʻi nā pahu pahu pahu) Ma muli o kāna mau pale kiʻekiʻe a me ke kumukūʻai haʻahaʻa.
ʻO Shore Aluminim Excel i ke kaupaonaʻana i ke kaupaonaʻana a iʻole corrosione-prone e hoʻohana i nā hihia.
Ua kāʻiliʻiaʻo aluminum kūpono no nā noi kiʻekiʻe?

Pehea e hoʻohālikelike ai ke kumukūʻai o Alumini e hoʻohālikelike i ka aluminim?
ʻO ka chore aluminum he 30-40% cheaper per kg ma mua o ka aluminim, E like me ka mālamaʻana o ka mea kūʻai aku i ka ikaika a me ka hoʻoiliʻana.
No nā'āpana kiʻekiʻe (100,000+ Nā'āpana), ʻoi aku ka nui o ka uku o ke kumukūʻai o ke kumukūʻai o ka alumini.
Hiki ke hoʻolei i ka alumini?
ʻAe-hapa nui loa alumini alloys (E.g., A356, 5052) ua weldtable ma ka tig (Gtaw) a mig paha (Kāmaʻa kikomua) me ka hoʻohanaʻana i nā metala filler (E.g., ER4043 no A356). ʻO nā'āpana kālā kiʻekiʻe (E.g., A380) koi i ka hana muaʻana e pale aku ai i ka paleʻana.
