Dab tsi yog 6061 Aluminium Phaj
6061 txhuas phaj yog magnesium{1}}silicon alloy los ntawm 6000 series, ntxiv dag zog los ntawm kev tsim cov magnesium silicide (Mg2Si). Nws muaj ib qho kev sib npaug zoo tshaj plaws ntawm lub zog, kev tiv thaiv corrosion, machinability thiab fabrication yooj ntawm txhua yam txhuas alloy, uas yog vim li cas nws yog ib qho tseem ceeb rau cov khoom siv, cov khoom siv thauj mus los thiab engineering.
Cov alloy belongs rau cov cua sov- tsev neeg kho tau: nws lub zog tuaj yeem nce ntxiv los ntawm kev tswj cov cua sov thiab cua txias, uas T6 temper yog qhov dav tshaj plaws.
6061 Aluminium Phaj Chemical Composition
Kev tswj hwm cov ntsiab lus alloying hauv 6061 tsim cov khoom muaj zog dua li cov ntshiab txhuas thaum tseem yoojyim rau tshuab, vuam thiab anodize. Feem ntau muaj pes tsawg leeg yog txhuas raws li qhov sib npaug, magnesium 0.80 txog 1.20 feem pua, silicon 0.40 txog 0.80 feem pua, tooj liab 0.15 mus rau 0.40 feem pua, chromium 0.04 mus rau 0.35 feem pua, hlau mus txog 0.70 feem pua, zinc mus txog 0.25 feem pua thiab 0.1 titanium li 0.1 feem pua.
Qhov kev sib xyaw no muab kev sib xyaw ua ke ntawm cov khoom siv dag zog, kev tiv thaiv corrosion thiab kev ua haujlwm ruaj khov, nrog rau cov cuab yeej txwv tsis pub dhau cov qauv xws li ASTM B209.
6061-T6 txhais li cas: Cov txheej txheem kho cua sov
Lub npe T6 piav qhia txog cov cua sov tshwj xeeb- txoj kev kho mob nrog peb theem. Ua ntej, kev kho cua sov: lub phaj yog rhuab mus rau kwv yees li 530 degrees Celsius kom magnesium thiab silicon dissolve uniformly nyob rau hauv aluminium matrix. Thib ob, quenching: ceev ceev, feem ntau yog nyob rau hauv dej, xauv lub alloying ntsiab nyob rau hauv qhov chaw. Thib peb, kev laus dag: lub phaj rov ua dua rau 160 txog 180 degrees Celsius rau ob peb teev, ua kom zoo Mg2Si precipitates uas ua rau kom muaj zog thiab hardness.
Cov txheej txheem tswj hwm no hloov tus qauv 6061 rau hauv siab -kev ua tau zoo 6061-T6 phaj, ua kom muaj zog thiab ua haujlwm ntev thaum khaws cia zoo corrosion kuj.
Mechanical Properties ntawm 6061-T6 Aluminium Phaj
Ua tsaug rau T6 temper, 6061 phaj ua tiav lub zog zoo heev - mus rau - qhov hnyav piv thaum seem yooj yim rau fabricate ntau dua - lub zog alloys. Cov txiaj ntsig zoo yog lub zog tensile ntawm 290 txog 320 MPa, yield zog tsawg kawg yog 240 MPa, elongation ntawm 8 mus rau 12 feem pua, qhov ceev ntawm 2.70 g ib cubic centimeter, thiab Brinell hardness txog 95 HB.
Cov khoom no ua rau 6061-T6 phaj haum rau kev thauj khoom- cov qauv kabmob, cov khoom siv tau zoo thiab cov kev pabcuam mus sij hawm ntev hauv qab kev ntxhov siab.
Corrosion Resistance ntawm 6061 Aluminium Phaj
6061 txhuas phaj resists corrosion zoo vim nws ruaj khov oxide txheej, enriched los ntawm magnesium thiab silicon. Nws muaj zog tiv thaiv huab cua thiab dej raug, txhim khu kev qha kev ua tau zoo nyob rau hauv cov av noo, muaj thiab marine ib puag ncig, thiab zoo tiv thaiv kev nyuaj siab corrosion cracking tshaj 7xxx alloys.
Hauv ntsev -txhaj tshuaj thiab raug dej hiav txwv, 6061-T6 phaj tuav cov qauv kev ruaj ntseg nrog qhov tsawg kawg nkaus oxidation, ua rau nws zoo tagnrho rau kev siv sab nraum zoov thiab ntug hiav txwv. Kev kho deg xws li anodizing, hmoov txheej thiab hard-coat finishing tuaj yeem txuas lub neej ua haujlwm ntxiv.
Machinability, Formability thiab Weldability
6061-T6 phaj tshuab ua kom huv si nrog cov cuab yeej carbide, tsim cov npoo du thiab tswj cov nti zoo ib yam, thiab nws txhawb nqa nruj kam rau ua thiab nyuaj geometries hauv CNC machining. Txawm hais tias nyuaj tshaj li annealed 6061-O, T6 phaj tseem tuaj yeem tsim nrog qhov tsim nyog bending radii, thiab hauv zos annealing tej zaum yuav raug siv rau nruj khoov.
Cov alloy welds zoo siv TIG thiab MIG txheej txheem. Thaum tshav kub kub- thaj tsam cuam tshuam txo qis lub zog hauv zos, yog li tom qab-weld aging lossis tsim qauv raug siv los ua kom muaj kev ntseeg tau ntawm cov qauv.
Daim ntawv thov ntawm 6061 Aluminium Phaj
6061-T6 phaj yog dav siv nyob rau hauv cov qauv thav duab thiab kab teeb, CNC-machined Cheebtsam, automotive thiab tsheb thauj mus los qhov chaw, aerospace fixtures thiab brackets, marine lug thiab kho vajtse, thiab industrial cov cuab yeej thiab cuab yeej. Nws qhov sib npaug ntawm lub zog, kev tiv thaiv corrosion thiab fabrication yooj ua rau nws nyiam alloy nyob rau hauv ntau lub lag luam.
Phaj yog feem ntau nkag rau hauv thicknesses ntawm 6 mus rau 150 hli, nrog widths mus txog 2600 mm thiab lengths mus txog rau 12000 mm, nrog rau precision - txiav tooling phaj thiab kev cai ntau thiab tsawg.
