Qhov sib txawv ntawm cov khoom thiab cov yam ntxwv ntawm cov alloys no txiav txim siab cov ntawv thov uas txhua tus yog qhov zoo tshaj plaws.
7075
Lub 7075 alloy tsis muaj qhov zoo tshaj plaws formability los yog weldability. Txawm li cas los xij, nws sawv tawm hauv siab - cov ntawv thov kev ntxhov siab uas yuav tsum muaj lub zog tshwj xeeb. Feem ntau hu ua "aircraft-qib" alloy, 7075 yog cov muaj zog aluminium alloys muaj nyob rau hauv khw.
Nws yog dav siv nyob rau hauv spacecraft, aircraft, missiles, thiab lwm yam kev tiv thaiv- hais txog daim ntawv thov. Koj tseem yuav pom 7075 feem ntau siv rau hauv cov khoom siv hnyav hnyav, khoom siv tub rog, thiab cov khoom siv.
6061
6061 aluminium alloy yog ntau yam ua tsaug rau nws txoj kev ua haujlwm zoo, kev tiv thaiv corrosion, lub zog, thiab kev sib koom ua ke. Nws yog dav siv nyob rau hauv ntau yam kev lag luam hauv kev siv xws li cov khoom sib dhos, cov khoom siv hluav taws xob, cov khoom siv hauv tsev, cov kav dej, cov hlua khi, thiab lwm yam. Common siv muaj xws li:
Rooj tog
Aircraft fittings thiab structural qhov chaw
Yachts, sailboats, marine hardware, thiab lwm yam shipbuilding Cheebtsam
Tsheb thauj mus los, nres tshuab, tsheb npav lub cev, hydraulic pistons, thiab lwm yam kev siv tsheb
Moldings
Awnings
Cov thawv ntim khoom noj thiab dej haus
Cov khoom siv fittings
6061 txhuas muaj nyob rau hauv ntau hom, nrog rau txhuas phaj, bar, thiab raj.
Qhov ntom
Thaum ntshiab txhuas sib koom tib qhov ntom ntom, ntxiv cov ntsiab lus alloying hloov tag nrho qhov ntom ntawm cov hlau kawg. Qhov ntom ntom yog qhov tseem ceeb thaum sib piv cov yam ntxwv ntawm lub cev ntawm cov hlau.
7075 aluminiummuaj qhov ceev ntawm2.81 g / cm³, siab dua cov ntshiab aluminium. Nws tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, nrog 7075-T6 yog qhov kub siab tshaj plaws.
6061 aluminiummuaj qhov ceev ntawm2.7 g / cm³, nyob ze ntawm cov ntshiab txhuas vim nws cov ntsiab lus siab aluminium.

Thermal conductivity
Thermal conductivity ntsuas npaum li cas cov ntaub ntawv hloov cua sov. Txawm hais tias ob qho tib si 6061 thiab 7075 yog cov cua sov- kho tau cov alloys, 7075 muaj zog dua thiab muaj qhov kub qis dua me ntsis.
6061 txhuas, los ntawm qhov sib piv, muaj cov thermal conductivity ntau dua, ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev hloov hluav taws xob zoo. Ntawm cov cua sov- kho cov kev xaiv, 6061 phaj yog suav tias yog ntau yam, tshwj xeeb tshaj yog vim nws cov corrosion kuj thiab siab toughness.
Cov lus kaw
Kev nkag siab qhov sib txawv ntawm ob lub alloys no -txawm tias lawv cov aluminium sib koom ua ke- pab kom ntseeg tau tias qhov kev xaiv raug tsim rau cov ntawv thov tshwj xeeb. Qhov sib ntxiv ntawm cov ntsiab lus alloying tau hloov pauv lawv qhov kev ua tau zoo, yog li kev sib piv 6061 thiab 7075 hauv kev nthuav dav yog qhov tseem ceeb.
