(Nkhani yachinayi: 2A12 aluminium alloy)

Ngakhale lero, mtundu wa 2A12 ukadali wokondeka pazamlengalenga. Lili ndi mphamvu zambiri komanso pulasitiki mu ukalamba wachilengedwe komanso wochita kupanga, zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri popanga ndege. Itha kusinthidwa kukhala zinthu zomalizidwa, monga mbale zoonda, mbale zokhuthala, mbale zosinthira magawo osiyanasiyana, komanso mipiringidzo yosiyanasiyana, mbiri, mapaipi, ma forgings, ndi ma forgings, ndi zina zambiri.

Kuyambira 1957, China bwinobwino opangidwa m'nyumba opangidwa 2A12 zotayidwa aloyi kupanga zigawo zikuluzikulu katundu wonyamula mitundu yosiyanasiyana ya ndege, monga khungu, mafelemu kugawa, mapiko amtengo, mbali mafupa, ndi zina zotero. Amagwiritsidwanso ntchito popanga zinthu zina zosanyamula katundu.

Ndi chitukuko cha makampani oyendetsa ndege, zinthu za alloy zikuchulukirachulukira. Choncho, pofuna kukwaniritsa zosowa za zitsanzo za ndege zatsopano, mbale ndi mbiri mu ukalamba wochita kupanga, komanso zizindikiro zina za mbale zakuda zochepetsera nkhawa, zapangidwa bwino ndikuyika kuti zigwiritsidwe ntchito.
