1. Mechanical Properties
Tensile zog:
Tom qab T6 kev kho cua sov, nws lub zog tensile tuaj yeem tshaj276 MPa ua(thaum lub 6061-O temper tsuas yog nyob ib ncig ntawm 110 MPa). Qhov no tso cai rau cov hlau kom tiv taus cov tensile tseem ceeb thiab ua tau raws li cov qauv kev xav tau ntawm cov khoom siv thauj khoom feem ntau.
Yield zog:
Lub zog tawm los yog kwv yees li241 MPa ua, txhais tau hais tias cov hlau tuaj yeem tiv taus lub zog sab nraud ua ntej deformation mus tas li. Qhov no yuav pab txo qhov kev pheej hmoo ntawm distortion thaum siv tiag tiag.
Elongation:
Elongation tseem nyob ntawm10%–14%, uas yog qhov pom tau tias siab dua qhov siab - lub zog steels (feem ntau qis dua 5%). Yog li, 6061-T6 muaj ob qho tib sisiab zog thiab zoo toughness, txo qhov kev pheej hmoo ntawm nkig tawg nyob rau hauv tam sim ntawd cuam tshuam.
Qhov kev sib xyaw ntawm no"siab zog + siab toughness"ua rau nws zoo tagnrho rau kev thauj khoom -cov kabmob (xws li kev txhawb nqa tshuab) nrog rau cov khoom uas yuav tsum tau muaj kev cuam tshuam (xws li tsheb sib tsoo beams).
2. Corrosion Resistance
Aluminium alloys ib txwm muaj qee qhov kev tiv thaiv corrosion, thiab kev ua haujlwm corrosion ntawm 6061-T6 tuaj yeem txhim kho ntxiv los ntawm ntuj oxidation lossis kev kho saum npoo.
Natural Corrosion Protection:
Hauv qhov chaw qhuav thiab huv si, qhov ntom ntomAl₂O₃ oxide zaj duab xiscov ntaub ntawv nyob rau saum npoo, zoo cais cov khoom los ntawm ya raws thiab huab cua los tiv thaiv sab hauv corrosion.
Ib puag ncig hnyav:
Hauv cov av ntub lossis ntsev-txhaj tshuaj tsuag (xws li marine lossis tshuaj chaw), kev kho mob zoo li anodizing lossis txheej txheej ua kom muaj kev tiv thaiv corrosion thiab ua haujlwm ntev.
Sib piv Advantage:
Thaum nws cov corrosion kuj yog me ntsis qis dua li ntawm cov ntshiab txhuas (1xxx series), nws yog qhov zoo dua li qhov siab -lub zog 2xxx thiab 7xxx series alloys. Qhov no ua rau 6061-T6 tus nqi kim heev- kev xaiv zoo nyob rau hauv cov nqe lus ntawm lub zog- rau- qhov sib npaug ntawm corrosion-resistant.
3. Machining Performance
Machineability:
Nrog ib tug nruab nrab hardness ntawm ib ncig95 HB, 6061-T6 tsis tshua muaj peev xwm ua rau cov cuab yeej adhesion thaum lub sij hawm machining thiab tuaj yeem ua tiav cov txheej txheem du, siab-precision nto tiav. Nws yog qhov tsim nyog rau kev tsim cov khoom sib xws xws li precision iav thiab hluav taws xob vaj tsev.
Formability:
6061 cov ntawv txhuas tuaj yeem dhau los ua ntau yam txias- cov txheej txheem ua haujlwm xws li extrusion, forging, thiab dabtsi yog khoov, tso cai rau lawv los ua cov profiles ntawm ntau yam ntoo khaub lig- ntu (xws li cov raj square thiab cov duab customized) kom haum rau ntau hom qauv tsim.
Weldability:
Siv TIG thiab lwm txoj kev vuam, cov pob qij txha tuaj yeem ncav cuagtshaj 80% ntawm lub hauv paus khoom siv zog. Tom qab vuam, kev kho cov laus hauv cheeb tsam tuaj yeem rov qab tau ib feem ntawm lub zog, ua rau nws tsim nyog rau kev tsim cov khoom sib dhos loj xws li thav duab thiab cov qauv kev txhawb nqa.
4. Qhov Zoo Tshaj Plaws
Qhov ceev ntawm 6061-T6 yog hais txog2.7 g / cm³, xwbib -peb qhov ceev ntawm cov hlau(kwv yees li 7.8 g / cm³), tab sis nws lub zog yog piv rau cov qis qis - carbon hlau.
Hloov cov hlau nrog 6061-T6 tuaj yeem txo qhov hnyav ntawm cov qauv.
Hauv tsheb, nws tuaj yeem txiav lub tsheb hnyav los ntawm15%–20%, txo cov roj noj.
Hauv aerospace, nws pab ncepayload muaj peev xwmthiabdav hlau dav.
