ʻO 2014 ka mea hoʻohui alumini alumini he keleawe, i kapa ʻia ʻo alumini paʻakikī. Loaʻa iā ia ka ikaika kiʻekiʻe a me ka hana ʻoki maikaʻi, akā maikaʻi ʻole kona kūpaʻa corrosion. Hoʻohana nui ʻia i nā hale mokulele (ka ʻili, ka iwi, ka iwi ʻaoʻao, bulkhead, etc.) rivets, missile parts, truck wheel hubs, propeller parts, a me nā mea hana ʻē aʻe.
Nā hiʻohiʻona o Aluminum 2014:
ʻO ka 2014 alumini alumini he alumini paʻakikī a me ka alumini alumini. Ke hoʻohālikelike ʻia me 2A50, no ka nui o ke keleawe kiʻekiʻe, ʻoi aku ka ikaika a ʻoi aku ka ikaika o ka wela, akā ʻaʻole maikaʻi kona plasticity i kahi kūlana wela e like me 2A50. 2014 alumini alumini he machinability maikaʻi, hoʻopili maikaʻi kuʻihao, wahi kuʻihao, a me ka humuhumu kuʻina, ilihune arc kuʻihao a me kinoea hana kuʻihao; hiki ke mālama ʻia ka wela a hoʻoikaika ʻia, me ka hopena extrusion.
Nā noi o Aluminum 2014:
Hoʻohana ʻia i nā noi e koi ana i ka ikaika kiʻekiʻe a me ka paʻakikī (me ka wela kiʻekiʻe). E like me nā hana koʻikoʻi o nā mokulele, nā forgings, nā papa a me nā mea i hoʻokuʻu ʻia, nā huila a me nā ʻāpana hoʻolālā, multi-stage rocket first stage pahu wahie a me nā ʻāpana mokulele, ka pahu kaʻa a me nā ʻāpana ʻōnaehana hoʻomaha.
Heat lapaʻau kiko'ī o Aluminum 2014:
1) Homogenization annealing: wela 475 ~ 490 ° C; paʻa 12 ~ 14h; kapuahi hooluolu.
2) Hoʻopili piha: hoʻomehana 350 ~ 400 ° C; me ka mānoanoa kūpono o ka mea, ʻo ka manawa paʻa he 30 ~ 120min; me ka mahana o 30 ~ 50 ° C / h me ka umu i hooluolu i 300 ° C, a laila ea-cooled.
3) Hoʻopili wikiwiki: hoʻomehana 350 ~ 460 ° C; manawa paʻa 30 ~ 120min; hooluolu ea.
4) Hoʻopiʻi a me kaʻelemakule: hoʻopau i ka 495 ~ 505 ° C, ka wai-ʻoluʻolu; ʻO ka mahana o ka lumi kahiko 96h.
Kūlana: extruded alumini a me ka alumini alumini pahu (≤22mm, H112, T6)
