7075 thiab 7050 yog ob qho tib si muaj zog aluminium alloys feem ntau siv hauv aerospace thiab lwm yam kev thov. Thaum lawv sib koom qee qhov sib xws, lawv kuj muaj qhov sib txawv tseem ceeb:
Kev sib xyaw
7075 txhuas alloyFeem ntau muaj txhuas, zinc, tooj liab, magnesium, thiab cov kab ntawm chromium. Nws yog qee zaum hu ua aircraft-qib alloy.
| Chemical Composition WT (%) | |||||||||
| Silicon | Hlau | Tooj | Magnesium | Manganese | Chromium | Zinc | Titanium | Lwm tus | Aluminium |

7050 aluminium alloykuj tseem muaj txhuas, zinc, tooj liab, thiab magnesium, tab sis nws feem ntau muaj zinc ntau dua piv rau 7075.

Lub zog
7075 paub txog nws lub zog tshwj xeeb, ua rau nws yog ib qho muaj zog tshaj plaws aluminium alloys muaj. Nws muaj lub zog tensile siab dua qhov kawg thiab lub zog tawm los piv rau 7050.
7050 muaj lub zog zoo heev, tab sis feem ntau nws muaj zog me ntsis qis dua piv rau 7075.
Corrosion Resistance
Ob lub alloys muaj kev tiv thaiv corrosion zoo, tab sis 7050 yuav muaj qhov zoo dua me ntsis rau kev ntxhov siab corrosion tawg piv rau 7075 vim nws cov ntsiab lus zinc ntau dua.
Fatigue Resistance
7050 feem ntau pom tias muaj kev qaug zog zoo dua piv rau 7075, ua rau nws tsim nyog rau cov ntawv thov uas lub voj voog thauj khoom lossis rov ua kev ntxhov siab yog kev txhawj xeeb.
Weldability
7050 muaj zoo weldability piv rau 7075. Txawm hais tias ob qho tib si alloys tuaj yeem welded, 7050 feem ntau tsis tshua muaj kev tawg thaum lub sij hawm vuam txheej txheem.
Daim ntawv thov
7075 feem ntau yog siv rau hauv cov qauv dav hlau, tsheb kauj vab ua haujlwm siab, phom, thiab lwm yam kev siv uas muaj zog-rau-qhov hnyav piv thiab qhov hnyav yog qhov tseem ceeb.
7050 kuj tseem siv rau hauv kev siv aerospace, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj zog, qaug zog zoo, thiab corrosion kuj yuav tsum tau, xws li aircraft fuselage thav ntawv thiab bulkheads.
Machineability
Ob lub alloys tuaj yeem ua tshuab, tab sis vim lawv lub zog siab, lawv tuaj yeem nthuav tawm cov teeb meem hauv machining. Txawm li cas los xij, 7050 yuav yooj yim me ntsis rau tshuab piv rau 7075.
