Cov Ntawv Qhia Tseem Ceeb:
Automotive: Cov pob zeb roj, cov panels lub cev, log, log, thiab cov roj teeb hluav taws xob (ua rau lub tsho hluav taws xob txo cov emissions thiab txuas ntxiv).
Ib tug tub rog: Cov dav hlau fuselages, tis, thiab interiors (high-zog alloys zoo li 7075).
Rail thiab Tubrog nkoj: Kev tsheb nqaj hlau tsheb ciav hlau siab ceev thiab lub nkoj.
Cov tsav tsheb: Ev kev loj hlob ntau lawm (EVs siv ~ 25% ntau dua txhuas dua li cov tsheb dej khov) thiab roj kev ua haujlwm.
3. Ntim
Qhia tawm: ~15–20%
Cov Ntawv Qhia Tseem Ceeb:
Cov kaus poom (ntau lawm ntau lawm: ~ 370 billion canss / xyoo, nrog 70% recycled cov ntsiab lus).
Ntawv ci rau cov khoom noj ntim khoom, cov tshuaj hlwv cov pob txha pob, thiab cov khoom siv kom pleev xim kom zoo nkauj.
Cov tsav tsheb: Hloov ntawm plastics rau cov khoom siv rov ua dua tshiab thiab xav kom yooj yim hauv kev xa khoom noj.
4. Hluav taws xob engineering thiab lub zog
Qhia tawm: ~10–12%
Cov Ntawv Qhia Tseem Ceeb:
Cov kab hluav taws xob thiab cov cable (Aluminium yog pheej yig dua thiab sib dua dua li tooj liab).
Cov Vaj Huam Sib Luag Hnub Ci Zog Cov Khoom Siv Hluav Taws Xob, Cov Hluav Taws Xob Hluav Taws Xob, thiab Lithium-ion Roj Teeb.
Rhaub sov so hauv Electronics (piv txwv li, smartphones, laptops).
Cov tsav tsheb: Qhov txuas ntxiv hluav taws xob nthuav dav thiab sib tw tshiab cov phiaj xwm.
5. Cov Machinery thiab Khoom Siv
Qhia tawm: ~8–10%
Cov Ntawv Qhia Tseem Ceeb:
Kev lag luam Machinery, khoom siv Hvac.
Robotics thiab Automation Cheebtsam.
Cov tsav tsheb: Kev tsim kev tsim khoom lag luam zoo li kev kho tsheb, aerospace, thiab electronics.
6. Cov neeg tau txais kev pab
Qhia tawm: ~5–7%
Cov Ntawv Qhia Tseem Ceeb:
Cov cuab yeej siv (tub yees, ntxhua khaub ncaws) thiab rooj tog.
Kev ntaus pob ncaws pob (tsheb kauj vab, cov koom haum ntaus pob) thiab cov neeg siv khoom siv hluav taws xob.
Cov tsav tsheb: Rising Rising OPPORABES THIAB thov rau lub teeb yuag, cov khoom lag luam ruaj.
Cov neeg tsav tsheb tawm
Cov Tsheb Hluav Taws Xob (EVS): Txhuas kev siv nyob rau hauv evs yog projected kom loj hlob los ntawm 10% txhua xyoo txog 2030.
Txuas lub zog txuas ntxiv: Hnub ci thiab cua thiab cua muaj peev xwm ntxiv 4-6 lab tons ntawm kev thov los ntawm 2030.
Ib tug tub rog: Tom ntej-gen agancraft (piv txwv li, boeing 787, Airbus A350) Siv 50-80% aluminium alloys.
Hloov pauv thaj tsam hauv cheeb tsam
Phiaj suav: Dominates thov (55% ntawm thoob ntiaj teb tag nrho), tsav los ntawm kev tsim kho thiab EVs.
North America thiab Europe: Tsom rau kev siv tsheb tsim hluav taws xob thiab ntim khoom ruaj khov.
Is Nrias teb thiab Southeast Asia: Cov txheej txheem txheej txheem tawm sai sai
Kev sib tw thiab tiam sis
Rov ua dua: Tsuas yog ~ 60% ntawm txhuas yog siv rov qab thoob plaws ntiaj teb, tawm hauv chav rau ncig kev lag luam kev lag luam.
Kev Raug Dab Neeg: Advanced composites and high-strength steel compete in automotive and aerospace.
Tseem Ceeb Takaway
Kev tsim kho, kev thauj mus los, thiab Ntim Ntim yog lub Bedrock ntawm Aluminium xav tau, thaum lub sij hawm EVS thiab txuas ntxiv sawv cev rau cov neeg nrawm. Aluminium lub luag haujlwm hauv Durarbonization thiab muaj kev tsim qauv kom ua kom ntseeg tau nws qhov kev txheeb ze hauv Net-xoom kev lag luam.
