Ma ke kakahiaka o ka lā 17, ua hoʻomau ka ʻoihana mokulele A-share i kona ʻano ikaika, me ka Hangfa Technology a me Longxi Shares e paʻi ana i ka palena o kēlā me kēia lā, a piʻi aʻe ʻo Hangya Technology ma mua o 10%. Ua piʻi mau ka wela o ke kaulahao ʻoihana. Ma hope o kēia ʻano mākeke, ua lilo ka hōʻike noiʻi i hoʻokuʻu ʻia e Tianfeng Securities i kumu catalytic koʻikoʻi. Hōʻike ka hōʻike noiʻi e hoʻomaka ana nā mokulele kalepa o Kina (COMAC) a me nā ʻenehana kalepa (COMAC) i nā manawa hoʻomohala mōʻaukala. Wahi a nā manaʻo hoʻohālikelike, ʻoi aku ka nui o ka noi no nā mīkini ʻoihana hou i ka mākeke kūloko ma mua o 600 biliona kālā ʻAmelika mai 2023 a 2042, me ka nui o ka mākeke makahiki ma mua o 200 biliona yuan.

Pili loa kēia wānana i ka hoʻonui ʻana i ka mana hana a me ka hoʻolako ʻana i ke kaʻina localization o nā mokulele nui C919 a me C929. He mea pono e hoʻomaopopo i ka hoʻohui ʻana i nā ʻoihana hana mokulele mokulele, nā mea hoʻolako o nā mea e like me ka titanium, aluminika, a me ke keleawe i ka ʻāpana metala non-ferrous e hōʻike pū ana i kahi ʻano hana. ʻO ka wikiwiki kūʻokoʻa a hiki ke hoʻopaʻa ʻia o ke kaulahao ʻoihana mokulele mokulele, i hui pū ʻia me ka catalysis o nā kulekele hoʻokele haʻahaʻa haʻahaʻa, ke hoʻololi nei i ka waiwai hoʻolālā o nā mea metala kiʻekiʻe i ka mākeke.

Titanium alloy: ka iwi kuamoʻo o nā mokulele nui kūloko

Ma ke ʻano he kumu māmā māmā no nā lako mokulele, ʻo ka titanium alloy he 9.3% o ka C919 kino kino, ʻoi aku ka kiʻekiʻe ma mua o ka Boeing 737. Me ka wikiwiki o ka hoʻonui ʻana i ka nui o nā mokulele mokulele nui, ʻo ke koi ʻana i nā mea titanium me ka mana hoʻokahi o kahi o 3.92 tons e hoʻonui i kahi mākeke hoʻonui nui. ʻO Baotai Co., Ltd., ma ke ʻano he mea hoʻolako kumu nui o nā mea titanium, ua komo nui i ka hana ʻana i nā mea koʻikoʻi e like me nā fuselage frames a me nā mīkini apo mīkini. Hiki i ka 3D paʻi ʻenehana ʻāpana titanium alloy i hoʻomohala ʻia e Western Superconductor hiki ke hoʻohaʻahaʻa nui i ke kaumaha o nā hale a hoʻohana mālie ʻia i ka hana ʻana i nā kaʻa mokulele unmanned hou a me eVTOL (electric vertical takeoff and landing vehicles).

Aluminum huila: he mīkini māmā no ka hoʻokele waiwai haʻahaʻa
Ma ke kahua o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, alumini alumini e noho i ka hapalua o ka mokulele structural mea. Loaʻa ka ikaika kiʻekiʻe o ka alumini alumini ma luna o 60% o ka fuselage a me nā ʻēheu i hāʻawi ʻia e AVIC Xifei no ka C919. Ua hōʻoia ʻia e ka COMAC ka pepa alumini alumini papa mokulele i hoʻomohala ʻia e Nanshan Aluminum Industry a ua hoʻopili ʻia i ka ʻili fuselage C919, ʻoi aku ka kiʻekiʻe ma mua o nā kiʻi alumini alumini kuʻuna. Wahi a nā kuhi, manaʻo ʻia ka koi makahiki no ka alumini ma nā mea haʻahaʻa haʻahaʻa haʻahaʻa o Kina e ʻoi aku ma mua o 500000 tons e 2030, me ka eVTOL nā pahu fuselage alumini a me nā hihia pākahi māmā e lilo i kumu ulu nui.

Copper zinc synergy: ʻelua hōʻoia o ka uila a me ka anti-corrosion
Hoʻokuʻu ʻia ka waiwai huna o ke keleawe ma nā ʻōnaehana uila lele. Ma nā huahana hoʻohui o AVIC Optoelectronics, ʻoi aku ka nui o ke keleawe maʻemaʻe no 70%, a ʻo ka laina hana hou i kūkulu ʻia ma kona kahua Lingang e hoʻokō i ka koi no nā ʻāpana keleawe aviation me ka waiwai hoʻopuka makahiki o 3 billion yuan. Hōʻike nā mea hoʻoheheʻe Zinc i ka maikaʻi o ke kumukūʻai i nā mokulele anti-corrosion a me ka hana ʻana i nā mea. Hoʻohana ʻo Hongdu Airlines i ka ʻenehana wela wela no ka mālama ʻana i nā ʻāpana mea hoʻokele, e hoʻonui ai i ke ola anti-corrosion ma mua o ʻekolu manawa a hoʻemi i nā kumukūʻai ma 40% i hoʻohālikelike ʻia i nā hopena i lawe ʻia mai. ʻO ka hoʻolālā localization no ka zinc aluminum alloy aviation material i hoʻomohala ʻia e Runbei Hangke ua hala i ka COMAC supply chain certification.

ʻO nā pilikia a me nā manawa kūpono: nā pilikia o ka hoʻonui ʻana i ka ʻoihana ma ka ʻāpana waiwai
ʻOiai ka nui o ka mākeke, mau ka bottlenecks i ka ʻenehana waiwai kiʻekiʻe. He 65% wale nō ka loaʻa ʻana o ka nui o ka loaʻa ʻana o ka ʻenehana ʻo Hangfa Technology i ka hana ʻana o ka ʻenekini, ʻoi aku ka haʻahaʻa ma mua o ka pae honua. Ma ka pae kulekele, ʻo ka Implementation Plan for Innovative Applications of General Aviation Equipment e manaʻo maopopo ana e hoʻokō i ka helu localization ma luna o 90% no nā alumini alumini papa mokulele a me nā alloys titanium e 2026, e hāʻawi i kahi puka aniani ʻenehana no nā ʻoihana e like me Baotai Group a me Western Superconductor. E like me ka helu ʻana o ke kula, ʻo ka awelika o ka ulu ʻana o ka hui ʻana o ka mākeke metala non-ferrous i nā makahiki ʻekolu e hiki mai ana e hiki i 25%, a ʻo nā ʻoihana me nā ʻenehana holoʻokoʻa holoʻokoʻa e manaʻo ʻia e pōmaikaʻi mai ka hoʻokaʻawale mua ʻana.
