7075 thiab 7050 yog ob qho tib si loj-zog aluminium alloys feem ntau siv nyob rau hauv aerospace thiab lwm cov ntawv thov. Thaum lawv sib koom qee qhov zoo sib xws, lawv kuj tau tseem ceeb tshaj plaws:
Muaj pes tsawg
7075 txhuas alloyMuaj cov thawj txhuas, zinc, tooj liab, magnesium, thiab cov chromium. Nws qee zaum tau hu ua lub dav hlau-qib alloy.

7050 Alloy Alloy AlloyKuj tseem muaj txhuas, zinc, tooj liab, thiab magnesium, tab sis nws feem ntau muaj cov ntsiab lus zinc ntau dua piv rau 7075.

Lub zog
7075 paub txog nws lub zog tshwj xeeb, ua rau nws muaj zog tshaj txhuas alloys muaj. Nws muaj lub zog tshaj plaws siab tshaj plaws thiab kom meej meej lub zog piv rau 7050.
7050 muaj lub zog zoo heev thiab, tab sis nws feem ntau muaj qis dua qis dua lub zog muaj txiaj ntsig piv rau 7075.
Corrosion Kuj
Ob lub alloys muaj zoo corrosion tsis kam, tab sis 7050 yuav muaj qhov zoo me ntsis rau kev cuam tshuam corrosion rau 7075 vim nws cov ntsiab lus zoo tshaj plaws zinc.
Qeeb zog tsis kam
7050 feem ntau ua rau muaj kev poob siab zoo dua piv rau 7075, ua rau nws siv zog ua haujlwm lossis kev ntxhov siab dua yog kev txhawj xeeb.
Hwj txwv
7050 muaj zoo dua weldability piv rau 7075. Thaum ob qho tib si alloys tuaj yeem welded, 7050 feem ntau yog feem ntau tsis tshua tawg thaum lub sij hawm vuam txheej txheem.
Cov Ntawv Thov
7075 feem ntau yog siv nyob rau hauv cov tsav tsheb dav hlau, phom sij, thiab lwm cov ntawv thov uas muaj zog piv thiab tawv yog qhov tseem ceeb heev.
7050 kuj yog siv nyob rau hauv ib daim ntawv thov aerospace, tshwj xeeb rau cov cheeb tsam uas muaj zog tsis kam, xws li aircraft fitelage thav ntawv thiab bulkheads.
Luam ntawv
Ob alloys tuaj yeem raug machined, tab sis vim lawv lub zog siab, lawv muaj peev xwm qhia cov kev cov nyom hauv machining. Txawm li cas los xij, 7050 yuav yooj yim me ntsis rau tshuab piv rau 7075.
