6061-T651 Rolled Phaj yog dab tsi?
6061-T651 yog ib lub tiaj- dov wrought aluminium khoom nyob rau hauv 6061 txhuas-magnesium-silicon alloy tsev neeg. T651 temper designation piav qhia txog txoj kev ua haujlwm tshwj xeeb: kev kho cua sov, kev ntxhov siab los ntawm kev tswj kev ncab, thiab kev laus. Cov kauj ruam stretching txawv T651 los ntawm tus qauv T6 temper; nws tshem tawm cov kev ntxhov siab seem kom lub phaj nyob ruaj khov thaum tshuab.
Raws li Lub Koom Haum Txhuas Txhuas, tiaj tus-cov khoom siv aluminium, suav nrog cov ntawv thiab phaj, sawv cev rau feem ntau ntawm cov khoom siv txhuas hauv Tebchaws Meskas, thiab cov khoom siv aluminium yog siv dav dua li cov castings, extrusion, forgings, los yog tuav. Rolled phaj yog tsim los ntawm dov mills uas hloov ingot rau hauv cov khoom lag luam tiaj tus nrog cov tuab tuab thiab cov cuab yeej siv tau zoo.
Kev tsim khoom
6061-T651 dov phaj yog tsim los ntawm cov txheej txheem wrought dov ua raws li peb cov kauj ruam tswj: kev kho cua sov, kev ntxhov siab los ntawm kev ncab, thiab kev laus. Kev kho cua sov kho dissolves cov ntsiab lus alloying rau hauv cov khoom sib xws; stretching relieves sab hauv kev ntxhov siab thiab txhim kho flatness stability; Artificial aging precipitates lub Mg2Si theem uas muab lub alloy nws lub zog. Qhov tshwm sim yog lub phaj nrog lub zog siab dua thiab txhim kho machinability piv nrog ntau lwm cov aluminium alloys.
Tshuaj muaj pes tsawg leeg
Raws li 6061 alloy, lub phaj muaj magnesium thiab silicon ua lub hauv paus tseem ceeb ntxiv dag zog rau cov ntsiab lus, nrog tooj liab thiab chromium raws li kev tswj hwm ntxiv. Cov muaj pes tsawg leeg muaj xws li silicon txog 0.4-0.8%, magnesium txog 0.8-1.2%, tooj liab txog 0.15-0.4%, hlau mus txog 0.7%, chromium 0.04-0.35%, zinc mus txog 0.25%, manganese mus txog 0.15%, thiab titanium 15% tshuav nyiaj li cas. Cov kev txwv tseeb ua raws li tus qauv tswj hwm xws li ASTM B209.
Physical thiab Mechanical Properties
Lub cev muaj zog ntawm 6061-T651 suav nrog qhov ceev ntawm 0.0975 lb/in3 (2.70 g/cm3), hluav taws xob conductivity ntawm li 47% IACS, thermal conductivity nyob ib ncig ntawm 1250 BTU-in/hr-ft2{{11}4} F, thiab cov nqi sib txawv ntawm 1 F. rau qhov hnyav-rhiab heev thiab kub-hloov daim ntaub ntawv.
Cov khoom siv kho tshuab sib txawv nrog cov tuab thiab kev ntsuas kev taw qhia. Cov ntawv luam tawm ntau yam thoob plaws tempers nthuav tawm lub zog ntawm kwv yees li 8-39 ksi thiab lub zog tensile ntawm 16-45 ksi, nrog elongation ntawm 12-25% thiab Brinell hardness ntawm 30-123. Nyob rau hauv T6 / T651 temper, raug lub zog tawm los yog nyob ib ncig ntawm 40 ksi thiab tensile zog nyob ib ncig ntawm 45 ksi. Modulus ntawm elasticity yog kwv yees li 10,000 ksi, thiab machinability Performance index yog li 30%. Cov neeg yuav khoom yuav tsum siv cov txheej txheem tswj hwm rau cov ntawv pov thawj yam tsawg kawg nkaus ntawm qhov tshwj xeeb thickness.
6061-T651 Rolled Phaj vs Cast Tool thiab Jig Phaj
Cam khwb cia cuab yeej thiab jig (CT thiab J) phaj yog tsim los ntawm ib txoj kev sib txawv thiab excels nyob rau hauv flatness thiab dimensional precision: raug thickness kam rau ua yog ntxiv los yog rho tawm 0.005 nyob rau hauv, thiab flatness sib txawv yog nruj heev nyob rau hauv tag nrho cov thicknesses. Rolled 6061-T651 muaj qhov sib txawv ntawm qhov sib txawv ntawm cov tuab, nrog kev sib txawv mus txog li 3/16 rau cov phaj ntawm 0.25 hauv thiab 3 hauv tuab.
Hauv cov ntsiab lus siv tshuab, 6061-T651 muaj lub zog ntau dua: cov txiaj ntsig zoo ntawm kwv yees li 40 ksi piv txog li 18 ksi rau cov cuab yeej cam khwb cia thiab jig phaj, nrog tensile lub zog nyob ib ncig ntawm 45 ksi piv rau 41 ksi, thiab Brinell hardness nyob ib ncig ntawm 95 superior piv rau 70. Thaum lub sij hawm machining, thaum 6061-T651 dov phaj muaj kev vuam zoo thiab muaj zog dua rau kev siv cov qauv.
Tej kev siv
6061-T651 dov phaj feem ntau yog siv rau hauv kev siv marine xws li nkoj thiab canoes, tsheb lub cev thiab cov khoom siv, scaffolding thiab kis tau tus yees, rooj tog thiab architectural structures, thiab cov khoom siv tshuaj lom neeg thiab khoom siv kho mob. Nws kuj yog cov khoom siv rau cov rooj sib dhos, pwm thiab tshuab hauv paus qhov chaw ruaj ntseg tom qab kev ntxhov siab yog qhov tseem ceeb.
Kev xaiv ntawm ob yam khoom
Xaiv 6061-T651 dov phaj thaum lub zog siab, hardness, weldability, thiab cov qauv kev ua haujlwm yog qhov tseem ceeb. Xaiv cov cuab yeej cam khwb cia thiab jig phaj thaum flatness, qhov tseeb qhov tseeb, thiab tsawg kawg machining distortion yog qhov tseem ceeb, xws li hauv precision jigs, fixtures thiab tshuaj xyuas cov cuab yeej.
FAQ
Q: T651 npau taws txhais li cas?
A: T651 txhais tau hais tias lub phaj yog kev daws cov cua sov- kho, kev ntxhov siab- txo qis los ntawm kev tswj kev ncab, thiab cov hnub nyoog tsis zoo. Cov kauj ruam stretching txo cov kev ntxhov siab seem kom zoo dua qhov seem stability thaum lub sij hawm machining.
Q: Qhov txawv ntawm T6 thiab T651 yog dab tsi?
A: Ob qho tib si yog cov hnub nyoog ua kom muaj zog tshaj plaws. T651 suav nrog kev ntxhov siab ntxiv- txo qis tom qab kev kho cua sov, uas txhim kho flatness stability thiab machined- ib feem raug.
Q: Puas yog 6061-T651 weldable?
A: Yog. 6061 welds ntseeg tau nrog tus qauv TIG thiab MIG cov txheej txheem siv 4043 lossis 5356 muab tub lim, thiab qhov sib koom ua ke tuaj yeem rov ua dua - hnub nyoog rau T6 cov khoom tom qab vuam thaum xav tau.
Q: 6061-T651 puas tuaj yeem ua anodized?
A: Yog, cov hlau anodizes zoo thiab ua kom zoo nkauj, tiv thaiv oxide tiav, txawm hais tias cov cuab yeej cam khwb cia thiab jig phaj feem ntau muab qhov zoo tshaj plaws anodized rau cov khoom kom zoo nkauj.
Q: Tus qauv twg npog 6061 dov phaj?
A: ASTM B209 yog kev tswj xyuas tshwj xeeb rau txhuas ntawv thiab phaj hauv Teb Chaws Asmeskas; GB / T 3880 yog tus qauv suav nrog. Yam tsawg kawg nkaus tus nqi sib txawv me ntsis ntawm cov khoom thiab thicknesses.
