Aluminium Alloy 6061 yog dab tsi?
6061 yog cov cua sov- kho tau wrought alloy nyob rau hauv 6000 series, ntxiv dag zog los ntawm magnesium thiab silicon, uas tsim magnesium silicide (Mg2Si) thaum lub sij hawm kev kho cua sov thiab kev laus. Ib qho me me tooj liab ntxiv nyob rau hauv thaj tsam ntawm 0.15-0.40% nce lub zog yam tsis muaj kev cuam tshuam cov weldability. Ua ntej tshaj tawm xyoo 1935, 6061 yog niaj hnub no yog ib qho ntawm cov khoom siv dav dav siv dav dav hlau alloys vim nws sib npaug zog, corrosion kuj, weldability thiab machinability.
Raws li qhov muaj pes tsawg leeg txwv nyob rau hauv ASTM B209 thiab GB / T 3880, cov hlau feem ntau muaj silicon 0.40-0.80%, magnesium 0.80-1.20%, hlau mus txog 0.70%, tooj liab 0.15-0.40%, chromium 0.04-0.35%. thiab titanium txog li 0.15%, nrog rau qhov sib npaug ntawm txhuas. Nyob rau hauv T6 temper, 6061 ncav cuag lub zog tawm los ze rau ntawm cov qauv me me ntawm ib feem peb ntawm qhov ceev (kwv yees 2.70 g / cm3 piv rau 7.85 g / cm3), uas yog vim li cas nws tau teev tseg qhov twg qhov hnyav.
Standard Product Forms thiab Kev Tswj Xyuas Cov Qauv
Vim tias 6061 extrudes zoo thiab tuaj yeem dov, kos thiab forged, nws tau muab rau hauv tsib daim ntawv tseem ceeb, txhua tus nrog nws tus kheej cov lus qhia. Daim ntawv thiab phaj yog them los ntawm ASTM B209 (nrog GB / T 3880 raws li Suav sib npaug) thiab siv rau cov qauv vaj huam sib luag, marine decking thiab hull plating, tso tsheb hlau luam, trailer pem teb thiab tshuab hauv paus. Bar thiab pas nrig nyob rau hauv puag ncig, square thiab hex duab yog them los ntawm ASTM B221 thiab pab machined qhov chaw, shafts, fasteners, valve Cheebtsam thiab spindles.
Kos seamless raj yog npog los ntawm ASTM B210 thiab haum rau cov qauv tubing rau thav ntawv, kua thiab pneumatic kab, tsheb kauj vab thiab rooj tog zaum, thiab tes tuav; extruded raj kuj poob rau hauv ASTM B221. Extruded profiles yog tswj hwm los ntawm ASTM B221 (nrog GB / T 6892 raws li Suav sib npaug) thiab siv rau lub qhov rais thiab qhov rooj thav duab, kab hlau rhuav - phab ntsa mullions, conveyor rails, cua sov dab dej thiab kev cai structural seem. Tuag forgings yog them los ntawm ASTM B247 thiab yog siv rau flanges, connectors, brackets, ncua kev kawm ntawv thiab chassis txuas, thiab hnyav - lub luag hauj lwm fittings.
Hom Dimensions thiab Muaj Tempers
Cov khoom siv zeb zoo li hauv qab no: daim ntawv thiab phaj ntawm 0.5 hli mus rau 150 hli tuab, nrog daim ntawv hauv qab 6.35 hli thiab phaj saum toj no; bar thiab pas nrig los ntawm 3 hli mus rau 500 hli txoj kab uas hla hauv zeb ntev ntawm 1000-6000 hli; seamless raj los ntawm 6 hli mus rau 300 hli sab nraud txoj kab uas hla nrog phab ntsa ntawm 0.5-10 hli; extruded profiles nrog ib tug raug circumscribed lub voj voog ntawm 30-300 hli ntawm nruab nrab presses thiab mus txog rau 500 hli ntawm loj presses; thiab tuag forgings los ntawm kwv yees li 0.1 kg mus rau 50 kg ib thooj rau cov qauv tuag, nrog loj dua tes forgings thiab dov rings muaj los ntawm cov lus hais.
Temper xaiv muaj xws li O (annealed), softest thiab feem ntau formable; T4, daws cov cua sov-kho thiab ib txwm muaj hnub nyoog rau nruab nrab lub zog thaum nyob hauv- txheej txheem tsim; T6 thiab T651, cov hnub nyoog tsim kom muaj zog siab nrog T651 ntxiv kev ntxhov siab rau phaj thiab bar; thiab H112, wrought, un-heat-kho temper qee zaus teev rau cov phaj tuab.
Cov ntawv thov los ntawm Daim Ntawv Thov Khoom
Daim ntawv thiab phaj nqa qhov zoo tshaj plaws ua ke ntawm flatness, weldability thiab corrosion kuj ntawm nruab nrab -lub zog alloys, uas yog vim li cas lawv dominate marine decking, hull plating, tsheb thiab trailer pem teb, chemical tanks thiab structural gussets. Nyob rau hauv T6 temper, phaj seem yog niaj hnub machined rau hauv fixture rooj, pwm thiab tshuab hauv paus vim hais tias cov khoom nyob twj ywm dimensionally ruaj khov tom qab kev ntxhov siab.
Bar thiab pas nrig yog lub neej ntawd feedstock rau tig thiab milled qhov chaw xws li shafts, spindles, fittings, valve lub cev thiab kev cai machined Cheebtsam; 6061 tshuab nrog luv luv, tawg chips thiab tuav nruj tolerances nyob rau hauv T6, uas ua rau machining nqi qis nyob rau hauv siab - ntim ntau lawm. Kos seamless raj muab ib tug du nto thiab zoo ib yam phab ntsa thickness rau structural tubing, handrails, ntaiv Cheebtsam thiab kua kab, thaum extruded profiles tsim complex cross-sections nyob rau hauv ib tug pass ib zaug, tshem tawm machining thiab koom cov kauj ruam. Tuag forgings dlhos cov nplej ntws nrog rau qhov contour, xa ntau zog qaug zog tshaj machined-los ntawm-bar sib npaug rau flanges, brackets, connectors thiab ncua kev kawm ntawv txuas.
Xaiv Daim Ntawv Zoo
Kev xaiv ua raws qhov geometry tsis yog qib ib leeg. Flat panels hu rau daim ntawv lossis phaj; puag ncig lossis prismatic machined qhov chaw hu rau bar; hollow seem hu rau raj; nyuaj tas li hla-sections hu rau profiles; thiab siab -load lossis kev nyab xeeb- cov duab tseem ceeb hu rau forgings. Ua ntej kev txiav txim, paub meej txog plaub yam: kev tswj hwm tus qauv thiab tsab ntawv, lub siab npau taws, chav kawm siab ntev, thiab seb cov khoom siv hluav taws xob puas yuav tsum tau lees paub rau tus qauv yam tsawg kawg nkaus lossis cov nqi luam tawm.
FAQ
Q: Qhov txawv ntawm 6061-T4 thiab 6061-T6 yog dab tsi?
A: T4 yog kev daws cov cua sov-kho thiab ib txwm muaj hnub nyoog mus rau nruab nrab lub zog (cov txiaj ntsig zoo li 145 MPa) thiab nyob ruaj khov dua. T6 yog cov hnub nyoog tsim nyog rau lub zog siab tshaj plaws (cov txiaj ntsig raug kwv yees li 275 MPa) thiab yog tus qauv txheej txheem temper; T651 ntxiv kev ntxhov siab rau cov phaj thiab bar.
Q: Tus qauv twg npog 6061 daim ntawv thiab phaj?
A: ASTM B209 yog kev tswj xyuas tshwj xeeb rau txhuas ntawv thiab phaj hauv Teb Chaws Asmeskas, thiab GB / T 3880 yog Suav sib npaug. Ob leeg qhia tib yam 6061 muaj pes tsawg leeg.
Q: 6061 puas tuaj yeem welded?
A: Yog lawm, qhov ntawd yog qhov tseem ceeb tshaj li xyoo 2024 thiab 7075. 6061 welds ntseeg tau nrog 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. Rau cov ntawv thov siab, qhov siv tau vuam thiab siab- cov lej code yuav tsum ua raws li ib txwm.
Q: Puas yog 6061 muaj raws li kos seamless raj?
A: Yog. Kos seamless raj yog them los ntawm ASTM B210 thiab extruded raj los ntawm ASTM B221. Seamless drawn tube yog qhov zoo dua qhov chaw ua tiav, phab ntsa zoo ib yam lossis siab ncaj ncees teeb meem.
Q: Dab tsi temper yuav tsum tau teev rau ib tug structural ncej?
A: T6 (los yog T651 rau phaj thiab bar) yog qhov kev xaiv tseem ceeb vim tias nws ua kom muaj zog thiab qaug zog ua haujlwm thaum ua kom cov hlau txuas tau zoo. Qhia meej O lossis T4 tsuas yog thaum tsim ntxiv yog npaj ua ntej kev kho cua sov zaum kawg.
