(Puka ʻehā: 2A12 alumini alumini)

ʻOiai i kēia lā, ʻo ka brand 2A12 kahi mea aloha o ka aerospace. Loaʻa iā ia ka ikaika kiʻekiʻe a me ka plasticity i nā kūlana kahiko a me nā mea kūlohelohe, e hoʻohana nui ʻia i ka hana mokulele. Hiki ke hana ʻia i nā huahana semi-finished, e like me nā papa lahilahi, nā papa mānoanoa, nā ʻāpana cross-section ʻano like ʻole, a me nā pā like ʻole, profiles, pipes, forgings, and die forgings, etc.

Mai ka makahiki 1957, ua hana maikaʻi ʻo Kina i ka 2A12 alumini alumini i hana ʻia i loko o ka hale no ka hana ʻana i nā mea lawe ukana nui o nā ʻano mokulele like ʻole, e like me ka ʻili, nā papa ʻāpana, nā ʻēheu beam, nā ʻāpana iwi, a pēlā aku. Hoʻohana ʻia ia no ka hana ʻana i kekahi mau mea lawe ukana ʻole.

Me ka hoʻomohala ʻana o ka ʻoihana mokulele, ke hoʻonui mau nei nā huahana alloy. No laila, i mea e hoʻokō ai i nā pono o nā mokulele mokulele hou, nā papa a me nā profiles i ke kūlana kahiko kahiko, a me kekahi mau kikoʻī o nā papa mānoanoa no ka hoʻoluhi pilikia, ua hoʻomohala maikaʻi ʻia a hoʻokomo ʻia no ka hoʻohana.
