7075-T6 txhuas alloy, muab los ntawmGNEE, yog lub siab - cov khoom siv zog tau tsim los rau kev siv dav hlau thiab aerospace thiab yog dav paub tias yogaircraft - qib aluminium. Alloyed feem ntau nrog zinc thiab tooj liab, 7075 qib ntawm cov muaj zog aluminium alloys muaj nyob hauv khw.
HauvT6 zog, 7075 txhuas ua rau muaj zog ntau dua cov hlau me me. Nws muaj cov machinability zoo thiab zoo corrosion kuj, tab sis nws feem ntau tsis pom zoo rau vuam.7075-T651 txhuassib koom cov khoom siv kho tshuab zoo sib xws nrog T6 tab sis ua rau muaj kev ntxhov siab ntxiv -txo cov txheej txheem, ua rau muaj kev ruaj ntseg zoo dua.
GNEEkhoom siv Aluminium Alloy 7075 nyob rau hauvT6 thiab T651 tempers, muaj nyob rau hauvphaj thiab round bardaim ntawv.

Puas yog 7075 Aluminium muaj zog li hlau?
Hauv ntau qhov xwm txheej,7075-T6 txhuas, muab los ntawmGNEE, achieves tensile zog nyob rau hauv ntau yam ntawm510-570 MPa, uas yog piv rau qee cov hlau me me uas feem ntau poob ntawm400 thiab 550 MPa. Txawm li cas los xij, siab dua - carbon thiab alloy steels tuaj yeem tshaj800 MPa, lub ntsiab lus 7075 txhuas tsis muaj zog tshaj txhua qib steel. Txawm li ntawd los, nwslub zog-rau- hnyav pivyog qhov tseem ceeb tshaj ntawm cov hlau, uas yog qhov zoo tshaj plaws hauv qhov hnyav - cov ntawv siv rhiab heev.
Puas yog 7075 Aluminium Durable?
Los ntawm kev xav engineering, 7075 txhuas muaj kev ua haujlwm zoo heev vim nwssiab qaug zog (nyob ib ncig ntawm 160 MPa), muaj zog tiv thaiv mus tas li deformation, thiab ruaj khov mechanical tus cwj pwm nyob rau hauv kev ruaj ntseg loads. Cov yam ntxwv no ua rau nws nyiam cov khoom siv rau aerospace thiab cov khoom tiv thaiv uas xav tau ntev - lub sij hawm kev ntseeg tau ntawm cov qauv.
7075 Aluminium puas tuaj yeem khoov?
7075 aluminium muajtxwv bendability, tshwj xeeb hauv covT6 los yog T651 tempers, qhov twg tensile zog saum toj no500 MPaho txo formability. Hauv ntau daim ntawv thov, khoov rau hauv cov xwm txheej no tuaj yeem ua rau tawg tshwj tsis yog tias cov khoom yog softened rauO kub, uas zoo heev txhim kho ductility. Thaum lub tshuab alloy zoo, nws feem ntau tsis haum rau kev ua haujlwm.
Vim li cas 7075 Txhuas Thiaj Nqis?
7075 txhuas feem ntau kim dua vim nwssiab alloying cov ntsiab lus, nrog rau zinc, magnesium, thiab tooj liab, nrog rau covcomplex heat-cov txheej txheem khoyuav tsum tau ua kom tau tempers xws li T6 los yog T73. Tsis tas li ntawd, aerospace- cov qauv qib, kev tswj xyuas nruj, thiab kev ua haujlwm zoo dua txhua yam ua rau muaj kev tsim khoom ntau dua thiab cov nqi lag luam.
Puas yog 7075 Aluminium Stronger dua Titanium?
Thaum sib piv cov ntaub ntawv,7075-T6 txhuasmuab lub zog tensile nyob rau hauv qhov ntau ntawm510-570 MPa, thaumQib 5 titaniummus txog kwv yees li900 MPa rau, ua titanium muaj zog nyob rau hauv cov ntsiab lus kiag li. Txawm li cas los xij, 7075 txhuas muaj alub zog zoo dua - rau - qhov hnyav pivthiab nws yooj yim dua rau tshuab, uas yog vim li casGNEEfeem ntau pom zoo nws rau lub teeb yuag structural Cheebtsam uas efficiency thiab manufacturability yog ib qho tseem ceeb.
