Raws li cov hlau sib txawv muaj nyob hauv txhuas, txhuas tuaj yeem muab faib ua 9 series. Hauv qab no, peb yuav qhia cov7 series aluminium:

 
Yam ntxwv ntawm7 series aluminiumcov ntaub ntawv:

 
Feem ntau zinc, tab sis qee zaum me me ntawm magnesium thiab tooj liab kuj ntxiv. Ntawm lawv, ultra hard aluminium alloy yog cov hlau uas muaj zinc, txhuas, magnesium, thiab tooj liab nrog hardness ze ntawm cov hlau. Lub extrusion ceev yog qeeb dua li ntawm 6 series alloy, thiab vuam kev ua tau zoo dua. 7005i ibib 7075yog cov qib siab tshaj plaws hauv 7 series thiab tuaj yeem ua kom muaj zog los ntawm kev kho cua sov.

Daim ntawv thov: aviation (load-bearing components of aircraft, landing gear), rockets, propellers, aerospace tsheb.

7005 cov khoom siv extruded yog siv los tsim cov qauv welded uas yuav tsum tau muaj lub zog siab thiab siab tawg toughness, xws li trusses, rods, thiab ntim rau tsheb thauj mus los; Cov khoom siv hluav taws xob loj loj thiab cov khoom siv uas tsis tuaj yeem raug kho fusion tom qab vuam; Nws tseem tuaj yeem siv los tsim cov khoom siv kis las xws li ntaus pob tesniv thiab cov pob mos mos.

 
7039 Lub thawv khov, cov khoom siv kub qis thiab cov thawv ntim khoom, cov khoom siv hluav taws kub, cov cuab yeej siv tub rog, daim hlau armor, cov khoom siv foob pob hluav taws.

 
7049 yog siv rau forging qhov chaw nrog tib lub zog zoo li 7079-T6 alloy tab sis yuav tsum muaj kev tiv thaiv siab rau kev ntxhov siab corrosion, xws li cov dav hlau thiab cov foob pob hluav taws - tsaws iav hydraulic thooj voos kheej kheej thiab cov khoom extruded. Kev ua haujlwm qaug zog ntawm cov khoom yog kwv yees li ntawm 7075-T6 alloy, thaum lub toughness yog me ntsis siab dua.

 
ib 7050Cov khoom siv dav hlau siv cov phaj tuab tuab, qhov chaw extruded, dawb forgings, thiab tuag forgings. Cov kev xav tau rau cov alloys hauv kev tsim khoom ntawm cov khoom zoo li no yog siab tiv thaiv corrosion, kev nyuaj siab corrosion cracking, tawg toughness, thiab qaug zog kuj.

 
7072 cua txias aluminium ntawv ci thiab ultra-thin strip; Txheej ntawm 2219, 3003, 3004, 5050, 5052, 5154, 6061, 7075, 7475, 7178 alloy nplooj ntawv thiab cov kav dej.

 
7075 yog siv los tsim cov qauv dav hlau thiab yav tom ntej. Nws yuav tsum muaj cov txheej txheem kev ntxhov siab siab nrog lub zog siab thiab muaj zog corrosion kuj, nrog rau kev tsim pwm.

 
7175 yog siv rau forging high-strength qauv rau aircraft. T736 cov ntaub ntawv muaj kev ua tau zoo tshaj plaws, suav nrog lub zog siab, tsis kam tiv thaiv corrosion thiab kev ntxhov siab corrosion tawg, tawg toughness, thiab qaug zog.

7178 Cov Kev Xav Tau rau Kev Tsim Lub Tsheb Aerospace: Cov Khoom Uas Muaj Cov Khoom Uas Muaj Zog Muaj Zog.
Lub 7475 fuselage yog ua los ntawm txhuas coated thiab uncoated panels, tis thav duab, kab teeb, thiab lwm yam khoom uas yuav tsum tau muaj ob qho tib si muaj zog thiab siab fracture toughness.

7A04 dav hlau daim tawv nqaij, ntsia hlau, thiab cov khoom siv thauj khoom xws li kab teeb, ncej, tav, tsaws iav, thiab lwm yam.
