Al 6061 yog dab tsi thiab nws Temper?
Txhawm rau pib, cia peb tshuaj xyuas cov hauv paus ntawm Al 6061 thiab nws qhov txawv ntawm kev npau taws. Al 6061 yog ib tsev neeg ntawm aluminium alloys uas siv magnesium thiab silicon ua cov ntsiab lus alloying, muab cov khoom nws zoo - paub cov yam ntxwv ua tau zoo.
Al 6061 tuaj yeem muab tau rau hauv ntau lub sijhawm, txhua tus tsim los ntawm cov cua sov tshwj xeeb- kho lossis cov khoom siv - cov txheej txheem txias. Cov kev kub ntxhov no, txhais los ntawm cov qauv xws li ANSI H35.1/H35.1(M), ua rau muaj kev sib txawv ntawm lub zog, ruaj khov, thiab ua haujlwm tau zoo.
Ntawm lawv,6061-T651thiab6061-T6yog ob qho kev siv ntau tshaj plaws. Nrog rau lub hauv paus hauv siab, tam sim no peb tuaj yeem pom tseeb piv aluminium 6061-T6 thiab 6061-T651.
Aluminium 6061-T6
Aluminium 6061-T6 yog qhov dav siv ntau dua ntawm ob. Nws cov txheej txheem tsim khoom suav nrog peb theem tseem ceeb:
Kev kho cua sov:
Lub alloy yog rhuab mus rau kwv yees li 550℃kom yaj cov alloying ntsiab uniformly rau hauv lub txhuas matrix.
Quenching:
Cov khoom yog txias sai heev-feem ntau nyob rau hauv dej- kom khaws cov khoom sib xws thiab tiv thaiv nag lossis daus ntxov thaum lub caij txias.
Kev laus:
Cov hlau yog reheated rau ib ncig ntawm 177℃rau ob peb teev (feem ntau 6-10 teev). Cov kauj ruam tswj kev laus no ua rau cov nag lossis daus ruaj khov ntawm cov ntsiab lus alloying, txhim kho hardness thiab lub zog. Cov khoom yog maj mam txias rov qab rau hauv chav tsev kub.
Qhov zoo thiab qhov txwv ntawm 6061-T6
6061-T6 muab lub zog tensile zoo heev (~ 290 MPa), muaj zog corrosion kuj, thiab siab thermal conductivity, ua rau nws tsim nyog rau kev thov siv xws li aerospace lug, automotive thav ntawv, thiab cov khoom ua haujlwm.
Txawm li cas los xij, cov txheej txheem ceev quenching tawm tom qab cov kev ntxhov siab uas seem, uas tuaj yeem ua rau cov duab distortion thaum lub sij hawm machining. Tsis tas li ntawd, thaum lub alloy welds zoo siv MIG los yog TIG, lub tshav kub - cuam tshuam cheeb tsam yuav muaj kev txo lub zog.
Aluminium 6061-T651
6061-T651 zoo ib yam li 6061-T6, tab sis suav nrog ib kauj ruam ntxiv uas cuam tshuam rau nws cov yam ntxwv ua haujlwm. Cov kauj ruam yog:
Kev kho cua sov:Ib yam li T6.
Quenching:Ib yam li T6.
Stretching:Cov khoom siv yog ncab 1-3% tom qab quenching los txo cov kev ntxhov siab hauv cov khoom thaum kho cua sov.
Kev laus:Ib yam li T6.
Qhov tsuas yog qhov sib txawv ntawm 6061-T6 thiab 6061-T651 yog qhov kev ntxhov siab-txhim kho cov kauj ruam-tsis tau qhov kev hloov me me no ua rau muaj txiaj ntsig zoo sib txawv.
Qhov zoo thiab qhov txwv ntawm 6061-T651
Vim tias kev ua haujlwm ncab tshem tawm cov kev ntxhov siab seem, 6061-T651 muaj qhov zoo dua qhov ruaj khov, ua haujlwm tau zoo, thiab kev ua haujlwm zoo sib xws piv rau 6061-T6.
Txawm li cas los xij, qhov kev ua haujlwm ntxiv no nce tus nqi thiab sijhawm ntau lawm. Txij li thaum kev txhim kho kev ua tau zoo yog nce ntxiv, T651 feem ntau tsuas yog siv thaum nruj dua thiab ruaj khov dua.
Al 6061-T651 vs Al 6061-T6
Nrog rau qhov sib txawv tam sim no tau qhia meej, peb tuaj yeem sib piv ob lub tempers ntawm cov yam ntxwv ntawm kev ua haujlwm.
Machineability
6061-T6:
Yooj yim rau tshuab, tab sis residual stresses yuav ua rau warping los yog distortion nyob rau hauv hnyav machining loads.
6061-T651:
Superior rau machining vim hais tias kev ntxhov siab nyem txo qis deformation thiab txhim kho thermal stability thaum txiav. Rau siab - precision machining thiab sab saum toj -tier nto finishes, manufacturers nyiam nyiam 6061-T651.
Dimensional Stability
Ob qib tau txais kev kho cua sov thiab quenching, tab sis qhov kev ntxhov siab ntxiv -relieving stretch nyob rau hauv 6061-T651 ua rau muaj kev ntxhov siab sab hauv. Qhov no ua rau T651 temper ruaj khov dua thaum machining nyias-walled los yog loj Cheebtsam, whereas 6061-T6 yog ntau nquag hloov me ntsis.
