1. Dab tsi yog 7075 Aluminium Alloy thiab Vim li cas thiaj suav hais tias yog ib qho khoom siv siab -Strength Material?
7075 aluminium alloy yog tus hwmAl-Zn-Mg-Cu series aluminium alloypaub txog nws qhov tshwj xeeb mechanical zog. Nws yog Ameslikas tsim rau kev siv aerospace, qhov twg cov ntaub ntawv yuav tsum tau ua raws li cov kev cai nruj rau lub zog, txo qhov hnyav, thiab kev ntseeg tau.
Lub ntsiab alloying nyob rau hauv 7075 txhuas yogzinc, txhawb los ntawm magnesium thiab tooj liab. Los ntawm kev tswj kev kho cua sov, cov ntsiab lus no tsim kom muaj zog precipitates nyob rau hauv aluminium matrix, ua rau muaj zog tensile thiab tawm los.
Piv nrog cov pa txhuas alloys, 7075 txhuas muaj:
Tsis tshua muaj siab tensile thiab yield zog
Lub zog zoo heev - rau - qhov hnyav piv
Kev qaug zog zoo
Vim yog qhov zoo,GNEE 7075 txhuas phaj, nplooj ntawv, thiab tuavyog siv dav hauv aerospace, tsheb thauj mus los, thiab siab -load industrial applications.
2. Vim li cas lub zog ntawm 7075 Txhuas tuaj yeem muab piv rau hlau?
Yog vim li cas 7075 txhuas tuaj yeem ua tiav qib siab ze rau qee cov hlau nyob hauv nwsalloy tsim thiab nag lossis daus -hardening mechanism.
Zinc plays lub luag haujlwm tseem ceeb los ntawm kev sib txuas nrog magnesium thiab tooj liab thaum kho cua sov los tsim cov khoom sib txuas zoo xws liMgZn₂. Cov precipitates zoo thaiv kev txav txav txav, uas yog qhov tseem ceeb ntawm cov yas deformation hauv cov hlau.
Tom qab kev kho cua sov, quenching, thiab kev laus dag:
Tensile zog tuaj yeem ncav cuag540-570 MPa
Yield zog tuaj yeem tshaj480-500 MPa
Txawm hais tias cov hlau tseem tuaj yeem muaj lub zog ntau dua, aluminium hnyav tsuas yog hais txogib -peb ntawm steel. Qhov no muab 7075 txhuas qhov zoo tshaj plawslub zog tshwj xeeb, ua rau nws zoo tagnrho rau lub teeb yuag qauv tsim.
3. Qhov txawv ntawm 7075-T6 thiab 7075-T651 Aluminium yog dab tsi?
Qhov txawv ntawm7075-T6thiab7075-T651 txhuaslus dag tsis nyob rau hauv tshuaj muaj pes tsawg leeg, tab sis nyob rau hauvtswj kev ntxhov siab thaum kho cua sov.
T6 zog: Kev daws cov cua sov- kho, quenched, thiab cov hnub qub
t651 ua: T6 txheej txheem + tswj kev ncab (1-3%) rau kev ntxhov siab
Cov kauj ruam ntxiv ntawm T651 txo qis kev ntxhov siab sab hauv, ua rau:
Zoo dua qhov seem stability
Tsawg deformation thaum lub sij hawm machining
Txhim kho qaug zog thiab kev nyuaj siab corrosion kuj
Rau siab - precision machining thiab tuab daim ntawv thov,GNEE pom zoo 7075-T651 txhuas, thaum T6 tseem tsim nyog rau cov ntawv thov uas tus nqi thiab lub zog siab tshaj plaws yog qhov kev txhawj xeeb tseem ceeb.
