Tshuaj muaj pes tsawg leeg: Aluminium 6061 vs 6063
Mechanical Properties ntawm Aluminium 6061 thiab 6063
Kev sib piv ntawm thermal thiab hluav taws xob conductivity
Thaum lub zog thiab formability yog qhov tseem ceeb thaum xaiv aluminium, thermal thiab hluav taws xob conductivity tuaj yeem cuam tshuam rau koj qhov kev xaiv -tshwj xeeb tshaj yog hauv cov ntawv thov uas cuam tshuam nrog kev hloov hluav taws xob lossis hluav taws xob hauv av.
Thermal conductivity:
Ob leeg GNEE 6061 thiab 6063 txhuas muab cov thermal conductivity zoo, tab sis 6063 feem ntau ua tau zoo dua me ntsis vim nws cov aluminium purity ntau dua thiab cov ntsiab lus qis alloying.
TIAB SA 6063: ~201–209 W/m·K
TIAB SA 6061: ~167–170 W/m·K
Qhov no ua rau GNEE 6063 qhov kev xaiv zoo tshaj plaws rau cov ntawv thov xws li LED vaj tse, cov dab dej kub, thiab cov vaj tsev fins qhov twg cov cua sov ua haujlwm tseem ceeb.
Hluav taws xob conductivity:
Ib yam li ntawd, GNEE 6063 muaj qhov zoo me ntsis hauv cov khoom siv hluav taws xob, ua kom nws zoo dua rau cov khoom siv hluav taws xob qis, cov av hauv av, lossis cov khoom siv kho kom zoo nkauj uas xav tau qee qhov kev ua haujlwm zoo.
TIAB SA 6063:53-56% IAB
TIAB SA 6061:40-44% IAB
Txawm li cas los xij, tsis yog cov hlau tsis sib xws rau kev ua tau zoo ntawm cov ntshiab txhuas los yog cov neeg xyuas tshwj xeeb-qib alloys (xws li 1350), yog li lawv siv hauv kev siv hluav taws xob feem ntau yog theem nrab lossis cov qauv.
Cov txheej txheem tsim khoom: Aluminium 6061 vs . 6063
Ntawm no yog saib ze dua ntawm GNEE 6061 thiab 6063 txhuas ua li cas hauv ntau yam kev lag luam.
Casting:
Casting yog txheej txheem tseem ceeb hauv aluminium alloy ntau lawm, tshwj xeeb tshaj yog rau kev tsim cov pob zeb siv hauv extrusion lossis forging. Muab piv GNEE 6061 thiab 6063 txhuas, 6063 qhia meej qhov zoo rau qhov loj - nplai, siab - ntim cov ntawv thov.
GNEE 6063 nta ib tug purer muaj pes tsawg leeg nrog tsawg alloying ntsiab, uas ua rau zoo heev casting txaus, txo susceptibility rau defects xws li porosity los yog inclusions, thiab txhim khu kev ruaj ntseg txheej txheem. Nws yog qhov tshwj xeeb tshaj yog zoo - haum rau ib nrab- nruam nruam ntawm cov ntawv ntev ntev, feem ntau ua haujlwm hauv cov qauv vaj tsev xws li lub qhov rais thav duab thiab cov khoom zoo nkauj extrusion.
Nyob rau hauv sib piv, GNEE 6061 muaj tooj liab thiab chromium, uas txhim khu lub zog tab sis ua rau casting ntau nyuaj. Kev tswj xyuas qhov kub thiab txias yuav tsum tau ua tib zoo txhawm rau tiv thaiv kev sib cais. Cov hlau no yog qhov zoo tshaj plaws siv rau kev ua cov pob zeb uas npaj siab rau siab - lub zog ntawm cov khoom siv, xws li tsheb thav duab lossis aerospace forgings.
Extrusion
Extrusion yog thawj txoj kev tsim rau 6xxx series txhuas, thiab qhov sib txawv ntawm cov yam ntxwv ntws ntawm cov alloys yog qhov tseem ceeb.
GNEE 6063 txhuas muab extrudability zoo heev vim nws cov ductility siab thiab zoo grain qauv. Nrog rau elongation tus nqi mus txog 25-30%, nws yog qhov zoo tagnrho rau kev tsim complex, nyias-walled, los yog ntev txhuas profiles xws li hniav trims, hollow qhov rais thav duab, los yog kab hlau rhuav phab ntsa. Nws cov kev ua tau zoo muaj xws li:
High extrusion ceev (txog 60-100 m / min)
Txo qhov hnav
Smooth nto tiav yuav tsum muaj tsawg kawg nkaus ncej- ua
GNEE 6061 txhuas, txawm tias muaj zog dua, muaj cov yas qis dua. Nws extrusion yuav tsum tau kub dua (500-520℃piv rau 480-500℃rau 6063) thiab ntau zog. Kev nrawm feem ntau qeeb qeeb (30-60 m / min), thiab yuav tsum tau saib xyuas kom tsis txhob tawg lossis tsis sib xws. Nws yog qhov zoo dua rau cov txheej txheem ntawm cov txheej txheem nyuaj, xws li kev txhawb nqa caj npab, ntsia hlau, lossis cov thav ntawv camper.
Rolling
Rolling converts aluminium rau hauv cov ntawv los yog daim hlau, qhov chaw zoo thiab tsis kam rau deformation yog qhov tseem ceeb. Kev xaiv ntawm 6061 thiab 6063 nyob ntawm daim ntawv thov.
GNEE 6063 zoo- haum rau nyias - ntsuas dov (0.3-3 mm). Nws cov plasticity zoo heev thiab kev ua haujlwm tsawg- hardening npaum li cas ua kom du, zoo ib yam (Ra < 0.8 μm), ua rau nws zoo tagnrho rau cov ntaub ntawv hlau los yog cov khoom uas yuav tsum tau ua ntxiv, xws li cov khoom siv casings lossis architectural cladding.
GNEE 6061 yog qhov zoo dua rau cov phaj nruab nrab mus rau tuab (3-100 hli) npaj rau kev siv cov qauv, suav nrog cov tshuab hauv paus, cov nkoj hauv hiav txwv, lossis hnyav- cov haujlwm ntas. Nws lub zog ntau dua yuav tsum muaj ntau dua dov quab yuam, thiab qhov nruab nrab annealing feem ntau yuav tsum tau tiv thaiv kev tawg.
CNC Machining: Precision & Nto tiav
Thaum machining GNEE 6061 thiab 6063, qhov kev xaiv nyob ntawm seb lub zog lossis qhov zoo ntawm qhov chaw yog qhov tseem ceeb.
GNEE 6063, ua softer, ua rau qis txiav tsis kam thiab huv si, tsis yog -clogging chips. Qhov no ua rau nws tsim nyog rau siab -ceev precision machining ntawm cov khoom siv kho kom zoo nkauj, xws li ornamental parts or slim shafts. Cov cuab yeej hnav tsawg tsawg, thiab siab - cov cuab yeej steel ceev feem ntau txaus.
GNEE 6061, tshwj xeeb tshaj yog nyob rau hauv T6 temper, muab superior zog (~ 290 MPa tensile) thiab seem stability. Nws xav tau cov cuab yeej carbide thiab siab dua txiav quab yuam. Cov chips yog nkig thiab tawg yooj yim, uas pab ua haujlwm zoo ntawm cov khoom siv xws li brackets, pob qij txha, lossis thauj khoom-cov kabmob vaj tse.
Sheet Hlau Vuam
Weldability yog qhov tseem ceeb hauv kev sib dhos thiab kev tsim khoom, tshwj xeeb tshaj yog rau kev siv vaj tse lossis vaj tse.
GNEE 6063 yog weldable heev vim nws cov chemistry huv si thiab tsis muaj tooj liab. Nws muaj qhov tsis zoo rau kub tawg thiab ua tau zoo nrog MIG / TIG vuam siv ER4043 muab tub lim. Weld seams muaj zog (txog 80% ntawm lub hauv paus hlau), ua rau nws zoo tagnrho rau kev sib txuas ntawm qhov rais thiab qhov rooj.
GNEE 6061, thaum weldable, yog qhov nyuaj dua vim nws cov ntsiab lus tooj liab ua rau muaj kev pheej hmoo ntawm kub tawg. ER5356 muab tub lim hlau raug pom zoo, thiab kev tswj xyuas cov cua sov yog qhov tseem ceeb. Tom qab-weld aging lossis localized kho cua sov feem ntau yuav tsum tau los kho cov neeg kho tshuab lub zog, tshwj xeeb tshaj yog rau load-cov kabmob welds hauv tsheb lossis aerospace cov qauv.
