M'mawa wa 17th, gawo la ndege la A-share lidapitilizabe mayendedwe ake amphamvu, pomwe Hangfa Technology ndi Longxi Shares akudutsa malire atsiku ndi tsiku, ndipo Hangya Technology ikukwera kuposa 10%. Kutentha kwa unyolo wamakampani kunapitilira kukwera. Kumbuyo kwa msika uwu, lipoti la kafukufuku lomwe latulutsidwa kumene ndi Tianfeng Securities lakhala chinthu chofunikira kwambiri. Lipoti la kafukufukuyu likuwonetsa kuti mafakitale aku China oyendetsa ndege (COMAC) ndi injini zamalonda (COMAC) akubweretsa mwayi wachitukuko chambiri. Malinga ndi kuyerekezera, kufunikira kwa injini zamalonda zatsopano pamsika wapanyumba kumatha kupitilira madola 600 biliyoni aku US kuyambira 2023 mpaka 2042, ndi msika wapachaka wamsika wopitilira 200 biliyoni.

Kunenedweratu kumeneku kumagwirizana kwambiri ndi kuchuluka kwa momwe angapangire komanso njira zogulitsira ndege zazikulu za C919 ndi C929. Ndizofunikira kudziwa kuti kuwonjezera pamakampani opanga ndege zachikhalidwe, ogulitsa zinthu monga titaniyamu, aluminiyamu, ndi mkuwa m'gawo lazitsulo zopanda chitsulo akuwonetsanso zomwe zikuchitika. Kuthamanga kodziyimira pawokha komanso kolamulirika kwamakampani oyendetsa ndege zamalonda, kuphatikizidwa ndi kuthandizira kwa mfundo zazachuma zotsika, zikukonzanso kufunikira kwa zida zachitsulo zokwera pamsika.

Titanium alloy: msana wa ndege zazikulu zapakhomo

Monga opepuka pachimake zakuthupi zipangizo ndege, titaniyamu aloyi nkhani 9.3% ya dongosolo C919 thupi, kwambiri kuposa Boeing 737. Ndi imathandizira Kukula kwa mphamvu zoweta zazikulu kupanga ndege, kufunika kwa zipangizo titaniyamu ndi limodzi unit mphamvu pafupifupi 3.92 matani adzapereka kuuka kwa msika waukulu wowonjezera. Baotai Co., Ltd., monga gawo lalikulu la zinthu za titaniyamu, yakhala ikukhudzidwa kwambiri pakupanga zinthu zazikulu monga mafelemu a fuselage ndi ma ring rings. Tekinoloje ya 3D yosindikiza titanium alloy component yopangidwa ndi Western Superconductor imatha kuchepetsa kwambiri kulemera kwa zomanga ndipo pang'onopang'ono ikugwiritsidwa ntchito popanga magalimoto apamlengalenga osayendetsedwa ndi m'badwo watsopano ndi eVTOL (magalimoto okwera okwera ndi magalimoto otera).

Aluminiyamu alloy: injini yopepuka yachuma chotsika
Pankhani yachuma chotsika, aluminium alloy imatenga theka la zida zamapangidwe a ndege. Aluminiyamu aloyi yamphamvu kwambiri imakhala yopitilira 60% ya fuselage ndi mapiko omwe amaperekedwa ndi AVIC Xifei pa C919. Tsamba la aluminiyamu yamtundu wa aluminiyamu yopangidwa ndi Nanshan Aluminium Viwanda yatsimikiziridwa ndi COMAC ndikuyika pakhungu la C919 fuselage, lalitali kwambiri kuposa mbiri yakale yamafakitale aluminiyamu. Malinga ndi kuyerekezera, kufunikira kwapachaka kwa aluminiyumu pazida zotsika kwambiri zaku China kukuyembekezeka kupitilira matani 500000 pofika 2030, pomwe eVTOL mafelemu onse a aluminiyamu a fuselage ndi mabatire opepuka amakhala malo akulu akulu.

Copper zinc synergy: chitsimikizo chapawiri chamagetsi ndi anti-corrosion
Phindu lobisika la mkuwa mu machitidwe amagetsi oyendetsa ndege akupitiriza kumasulidwa. M'zinthu zolumikizira za AVIC Optoelectronics, mkuwa woyengedwa kwambiri ndi 70%, ndipo mzere wongomanga kumene pamalo ake a Lingang udzakwaniritsa kufunikira kwa ma aloyi amkuwa omwe ali ndi mtengo wapachaka wa yuan 3 biliyoni. Ma aloyi opangidwa ndi zinc amawonetsa zabwino zake pakuchita bwino kwa ndege zolimbana ndi dzimbiri komanso kupanga zinthu. Hongdu Airlines imagwiritsa ntchito ukadaulo wothira mafuta otenthetsera kuti athetse zida zoyatsira, zomwe zimawonjezera moyo wodana ndi dzimbiri kupitilira katatu ndikuchepetsa mtengo ndi 40% poyerekeza ndi mayankho ochokera kunja. Dongosolo lakumalo la zinc aluminiyamu alloy aviation zida zopangidwa ndi Runbei Hangke zadutsa chiphaso cha COMAC.

Zowopsa ndi Mwayi: Zovuta Zokweza Mafakitale M'gawo la Zida
Ngakhale kuti msika uli ndi malo ambiri, zolepheretsa zamakono zamakono zamakono zilipobe. Kutentha kwambiri kwa Hangfa Technology kumatulutsa alloy pakupanga masamba a injini ndi 65% yokha, yomwe ndi yotsika poyerekeza ndi mayiko ena. Pa mulingo wa mfundo, ndi Implementation Plan for Innovative Applications of General Aviation Equipment ikufuna kukwaniritsa kuchuluka kwa malo opitilira 90% kwa ma aloyi a aluminiyamu amtundu wa ndege ndi ma aloyi a titaniyamu pofika chaka cha 2026, chomwe chidzapereka zenera laukadaulo wamabizinesi monga Baotai Gulu ndi Western Superconductor. Malinga ndi kuwerengetsera kwamabungwe, kuchuluka kwapachaka kwa msika wazinthu zachitsulo zosakhala ndi chitsulo mzaka zitatu zikubwerazi kudzafika 25%, ndipo mabizinesi omwe ali ndi luso laukadaulo waukadaulo akuyembekezeka kupindula ndi gawo loyamba lolowa m'malo.
