Hauv lub ntiaj teb uas cov khoom siv sib dua thiab sib dua uas hloov pauv sai sai, muaj ob peb qhov kev sib cav sib ceg uas ua rau cov engineers xav tsis thoob li 6061 piv rau 7075 txhuas. Ob qho txhuas no muaj zog tshaj plaws hauv kev ua tau zoo: 6061 yog cov khoom siv txhim khu kev qha uas pom muaj nyob rau hauv txhua yam los ntawm cov thav tsheb kauj vab mus rau cov qauv tsheb, thaum 7075 yog tus yeej muaj zog heev uas muab zog rau cov tis dav hlau thiab cov khoom siv kis las siab. Nrog rau qhov kev thov txhuas nce siab hauv xyoo 2026 - ua tsaug rau EV platform sib dua, drone ntau zuj zus, thiab kev tsim kho kom ruaj khov - kev xaiv ntawm lawv tuaj yeem ua rau lossis rhuav tshem tus nqi tsim, kev ruaj khov, thiab kev ua tau zoo.
Kev siv cov hlau txhuas thoob ntiaj teb kwv yees tias yuav tshaj 78 lab tons xyoo no, nrog rau6xxx thiab 7xxxCov qib series ua tus thawj coj hauv kev siv cov qauv. Cov nqi rau ob qho tib si 6061 thiab 7075 tseem siab, nrog 7075 hais kom muaj 20-40% nqi vim nws cov zinc thiab kev ua haujlwm nyuaj. Nov yog qhov kev faib tawm tsis muaj lus tsis txaus ntseeg ntawm lawv cov khoom sib sau ua ke, raws li cov khoom tiag tiag, kev siv, lub zog, qhov tsis muaj zog, thiab thaum twg ib qho ua tau zoo dua lwm qhov.

Piv txwv li, hauv kev tsim EV, ntau lub tuam txhab tsim khoom sib xyaw ob qho tib si: 6061 rau cov qauv lub cev weldable thiab 7075 rau cov kev thauj khoom tseem ceeb xws li kev dais.
Cov Xwm Txheej Sib Piv ntawm Lub Taub Hau
- Cov Kev Xav Tau ZogYog tias koj xav tau >500 MPa tensile, 7075 yeej tsis muaj teeb meem. Rau 300–400 MPa, 6061 muab 80% ntawm kev ua tau zoo ntawm 60% ntawm tus nqi.
- Kev Raug Tshuaj Corrosion6061 yog qhov kev xaiv meej meej sab nraum zoov lossis hauv qhov chaw noo noo. 7075 xav tau Alclad txheej lossis txheej txheej kom phim.
- Kev Yooj Yim Tsim Khoom6061 yog qhov zam txim ntau dua rau kev vuam thiab kev tsim khoom - zoo tagnrho rau cov qauv lossis kev tsim khoom nruab nrab.
- Qhov Hnyav Tseem Ceeb: 7075 qhov ceev dua yog offset los ntawm cov seem thinner ua tau vim muaj zog dua.
- Kev Nkag Siab Txog Tus Nqi6061 muaj tus nqi zoo dua rau feem ntau cov ntawv thov lag luam; 7075 ua pov thawj nws qhov hwm hauv kev tsav dav hlau lossis kev tiv thaiv qhov twg kev ua tsis tiav tsis yog qhov kev xaiv.
Xyoo 2026 Cov Qauv Lag Luam Uas Cuam Tshuam Rau Kev Xaiv
Cov khoom siv rov ua dua tshiab (tam sim no > 40% hauv ntau lub Hoobkas) tab tom ua kom qhov sib txawv ntawm tus nqi nqaim dua, thaum cov kev nce qib tshiab ntawm kev kho cua sov tab tom txhim kho 7075 qhov kev tiv thaiv xeb (nrhiav cov T73 / T77 tempers tshiab). Lub caij no, 6061 variants nrog ntxiv scandium yog boosting lub zog rau EV daim ntawv thov. Cov kev cai tswjfwm kev ruaj khov hauv Tebchaws Europe thiab California tab tom thawb clad 7075 thiab anodized 6061 rau lub neej ua haujlwm ntev dua.
Lub ntsiab lus tseem ceeb: Tsis muaj ib qho yeej uas zoo rau txhua tus—6061 yog tus phab ej uas siv tau txhua hnub, thaum 7075 yog lub zog tshwj xeeb. Sib phim cov hlau sib xyaw kom haum rau koj qhov tseem ceeb: nyiaj txiag thiab kev tsim khoom nyiam 6061; kev ua tau zoo tshaj plaws nyiam 7075.
