Ekuseni ngomhla ka-17, umkhakha wezindiza we-A-share waqhubeka nokuthambekela kwawo okuqinile, i-Hangfa Technology kanye ne-Longxi Shares zifinyelela umkhawulo wansuku zonke, kanti i-Hangya Technology ikhuphuke ngaphezu kwe-10%. Ukushisa kochungechunge lwemboni kuqhubekile nokukhuphuka. Ngemuva kwalo mkhuba wemakethe, umbiko wocwaningo osanda kukhishwa yi-Tianfeng Securities usuphenduke into esemqoka ebambekayo. Umbiko wocwaningo uveza ukuthi izimboni zezindiza zezentengiselwano zaseChina (COMAC) kanye nezinjini zezohwebo (COMAC) zingenisa amathuba omlando wentuthuko. Ngokwezilinganiso, isidingo sezinjini ezintsha zezentengiselwano emakethe yasekhaya singase seqe amaRandi ayizigidi eziyizinkulungwane ezingama-600 kusukela ngo-2023 kuya ku-2042, ngosayizi wezimakethe wonyaka ongaphezu kwama-yuan ayizigidi eziyizinkulungwane ezingama-200.

Lesi sibikezelo sihlobene eduze nokwanda kwamandla okukhiqiza kanye nenqubo yokwenziwa kwasendaweni kochungechunge lokuhlinzeka ngendiza enkulu ekhiqizwe ekhaya i-C919 ne-C929. Kuyaphawuleka ukuthi ngaphezu kwamabhizinisi endabuko akhiqiza izindiza, abahlinzeki bezinto ezifana ne-titanium, i-aluminium, nethusi emkhakheni wensimbi engeyona insimbi nabo babonisa umkhuba osebenzayo. Ukusheshisa okuzimele nokulawulekayo kochungechunge lwemboni yezokundiza kwezentengiselwano, okuhambisana nokusungulwa kwezinqubomgomo zomnotho ezisezingeni eliphansi, kubunjwa kabusha inani lesu lezinto ezibalulekile zensimbi ezikhuphuka nomfula emakethe.

I-Titanium alloy: umgogodla wendiza enkulu yasekhaya

Njengento ewumgogodla engasindi yemishini yendiza, i-titanium alloy yenza u-9.3% wesakhiwo somzimba we-C919, ephakeme kakhulu kunaleyo ye-Boeing 737. Ngokukhula okusheshayo kwamandla okukhiqiza indiza enkulu yasekhaya, isidingo sezinto ze-titanium ezinomthamo owodwa weyunithi cishe amathani angu-3.92 kuzodala imakethe enkulu ekhulayo. I-Baotai Co., Ltd., njengomphakeli oyinhloko wezinto zokwakha ze-titanium, ibambe iqhaza ngokujulile ekukhiqizeni izingxenye ezibalulekile ezifana namafreyimu e-fuselage kanye nama-ring ring yenjini. Ubuchwepheshe bengxenye ye-3D yokuphrinta ye-titanium alloy ethuthukiswe yi-Western Superconductor bunganciphisa kakhulu isisindo sezakhiwo futhi kancane kancane busetshenziswa ekukhiqizeni izimoto zasemoyeni ezinganamuntu wesizukulwane esisha kanye ne-eVTOL (ukusuka okukagesi okume mpo kanye nezimoto ezihlala phansi).

Ingxube ye-aluminium: injini engasindi yomnotho osezingeni eliphansi
Emkhakheni womnotho osezingeni eliphansi, ingxubevange ye-aluminium ithatha ingxenye yezinto zesakhiwo sendiza. Ingxubevange ye-aluminium enamandla amakhulu ingaphezu kuka-60% we-fuselage nezingxenye zamaphiko ezinikezwe i-AVIC Xifei ye-C919. Ishidi le-aviation aluminium alloy grade elakhiwe yi-Nanshan Aluminium Industry ligunyazwe yi-COMAC futhi lafakwa esikhumbeni se-C919 fuselage, esiphakeme kakhulu kunamaphrofayili e-aluminium endabuko embonini. Ngokwezilinganiso, isidingo sonyaka se-aluminium emishinini yokuphakama ephansi yaseChina kulindeleke ukuthi sidlule amathani angu-500000 ngo-2030, kanti i-eVTOL wonke amafreyimu e-aluminium fuselage namakesi ebhethri angasindi abe yizindawo zokukhula eziyinhloko.

I-Copper zinc synergy: isiqinisekiso esikabili sikagesi kanye ne-anti-corrosion
Inani elifihliwe lethusi ezinhlelweni zikagesi zezindiza liyaqhubeka nokukhishwa. Emikhiqizweni yokuxhuma ye-AVIC Optoelectronics, i-high-purity copper yenza u-70%, kanti ulayini wokukhiqiza osanda kwakhiwa endaweni yawo yaseLingang uzohlangabezana nesidingo sama-alloys ethusi ebanga lezindiza anenani eliphumayo lonyaka lama-yuan ayizigidi eziyizinkulungwane ezintathu. Ama-alloys asekelwe ku-Zinc abonisa izinzuzo zokuphumelela kwezindleko zezindiza ezilwa nokugqwala kanye nokukhiqizwa kwezingxenye. I-Hongdu Airlines isebenzisa ubuchwepheshe bokudonsa amanzi ashisayo ukwelapha izingxenye zegiya lokuhlala, okwandisa impilo yokunqanda ukugqwala izikhathi ezingaphezu kwezintathu futhi kunciphisa izindleko ngo-40% uma kuqhathaniswa nezixazululo ezivela kwamanye amazwe. Uhlelo lwendawo lwezinc aluminium alloy aviation materials oluthuthukiswe ngu-Runbei Hangke luphasise isitifiketi se-COMAC supply chain.

Ubungozi Namathuba: Izinselelo Zokuthuthukiswa Kwezimboni Emkhakheni Wezinto Zokusebenza
Naphezu kwesikhala esikhulu semakethe, izingqinamba kubuchwepheshe bezinto ezisezingeni eliphezulu zisekhona. Izinga lokuvunwa kwe-alloy ephezulu ye-Hangfa Technology ekukhiqizeni amalahle enjini lingama-65% kuphela, elingaphansi kwezinga lamazwe ngamazwe. Ezingeni lenqubomgomo, Ukuqaliswa Kohlelo Lwezicelo Ezintsha Zezinsiza Zokusebenza Zezindiza Ngokusobala liphakamisa ngokusobala ukuzuza izinga lendawo elingaphezu kuka-90% lamaalloyi e-aluminium ebanga lezindiza kanye nama-titanium alloys ngo-2026, okuzohlinzeka ngewindi lempumelelo kwezobuchwepheshe kumabhizinisi afana ne-Baotai Group kanye ne-Western Superconductor. Ngokwezibalo zesikhungo, isilinganiso sokukhula kwesilinganiso sonyaka sokukhula kwemakethe yezinto zensimbi ezingenayo insimbi eminyakeni emithathu ezayo sizofinyelela ku-25%, futhi amabhizinisi anamakhono okusebenza ngokugcwele kwezobuchwepheshe kulindeleke ukuthi ahlomule emalini yokushintshanisa yasekhaya kuqala.
