6061 Anodized Equal Angle ntawm ib sab
6061 anodized vaj huam sib luag txhuas lub kaum sab xis yog ib qho extruded Al-Mg-Si L- profile nkag rau hauv T6 lossis T651 temper thiab ua tiav nrog sulfuric acid anodic zaj duab xis. Cov alloy nqa nominally 0.8-1.2% Mg thiab 0.4-0.8% Si, nrog 0.04-0.35% Cr ntxiv rau refine grain qauv thiab offset cov teebmeem ntawm hlau impurities. Cov ceg sib npaug yog tsim tawm thoob plaws ntau qhov loj, feem ntau ntawm 10 × 10 mm txog 150 × 150 mm, nrog phab ntsa thickness ntawm 1 mm txog 20 mm thiab zeb ntev ntawm 3000–6000 mm. Lub tshav kub- kho tau matrix muab txoj kev thauj khoom; cov tawv oxide tawv muab kev puas tsuaj thiab kev tiv thaiv corrosion. Qhov kev sib koom ua ke yog vim li cas qhov profile raug xaiv rau kev saib xyuas lub tshuab, conveyor thav duab, kev txhawb nqa busbar, rail sab hauv cov qauv, marine outfitting thiab tsheb lub cev sub-thav duab, qhov twg lub pob zeb liab qab yuav stain thiab gall nyob rau hauv ob peb lub hlis ntawm kev pabcuam.

Yam tsawg kawg nkaus ua raws li qhov extruded bar thiab cov qauv ntawm ASTM B221; cov txiaj ntsig zoo ib txwm yog ntsuas ntawm kev lag luam xovxwm -quenched, laus extrusion. Lub temper annealed tau teev los ntawm lub zog siab tshaj plaws kom tsim thiab khoov nyob twj ywm, uas yog vim li cas O- lub kaum sab xis yog yuav rau yob- tsim los yog nruj- vojvoog ua haujlwm thiab T6 lub kaum sab xis rau kev ua haujlwm.
Extrusion, Quenching thiab Aging xyaum
6061 yog qhov ua kom muaj zog ntau dua -rhiab dua li lean 6063 alloy, yog li qhov ntsuas cua txias ntsuas los ntawm lub sijhawm qhov profile tawm ntawm qhov tuag teeb tsa lub qab nthab ntawm lub zog kawg. Billet yog rhuab mus rau kwv yees li 450-500℃thiab extruded ntawm lub thawv kub ntawm 400-480 degree; cov profile ces dhau los ntawm cov tshuaj tsuag dej hauv kab lossis cov dej hauv dej hauv ob peb vib nas this, poob qis dua 200℃sai txaus kom Mg thiab Si hauv cov tshuaj supersaturated. Lub cua txias qeeb tuaj yeem raug nqi 20-30% ntawm lub zog tensile ua tiav txawm tias lub voj voog kev laus tom ntej yog qhov tseeb, thiab qhov poob tsis tuaj yeem rov qab los ntawm kev laus dua. Tom qab quenching, qhov ntev yog stretched los yog straightened, txiav thiab ces artificially hnub nyoog ntawm roughly 175℃rau 8 h mus txog T6. Qhov chaw ruaj ntseg tom qab machining yog qhov tseem ceeb - ntev ncej ntsia hlau, clamping daim hlau, neeg hlau lem, kho qhov muag benches - T651 temper tau teev tseg xwb: tib lub voj voog kev laus ua raws li kev tswj kev ncab li ntawm 1-3% uas txo cov kev ntxhov siab thiab txwv kev cuam tshuam thaum lub sij hawm milling.
Anodic Zaj duab xis tsim-Ua thiab Corrosion Cwj Pwm
Hom II sulfuric acid anodizing khiav ntawm 15-20 V DC hauv electrolyte ntawm 165-200 g / L sulfuric acid tuav ntawm 18-22 degree. Cov txheej txheem tiv thaiv thiab cov yeeb yaj kiab zoo nkauj yog 10-25 µm tuab thiab ncav cuag 400-600 HV ntawm micro- hardness nplai, yog li qhov saum npoo tiv thaiv kev puas tsuaj thiab tuav kev puas tsuaj zoo dua li zeb tiav thaum lub substrate hauv qab khaws nws cov ductility. Cov txheej txheem loj hlob raws li cov kab nrib pleb, cov qauv ntxeem tau uas yuav tsum tau muab khi: kub deionised dej sealing los yog npib tsib xee acetate sealing kaw lub qhov hws, thiab nws yog lub kaw ntom ntom uas tsim nyog rau MIL-A-8625 Hom II. Cov txheej txheej kaw rau ntawm 6061 cov ntaub ntawv yog niaj hnub tsim nyog rau 336 h ntawm nruab nrab ntsev tsuag ib ASTM B117 yam tsis muaj pitting, thiab txheej txheej ntawm ib cheeb tsam ib cheeb tsam raug txheeb xyuas raws li ASTM B137. Nyob rau sab substrate, Mg2Si theem muab cov alloy nws lub ntuj tsis kam rau atmospheric thiab dej hiav txwv nres, thiab 6061 nyob rau hauv lub T6 temper yog tsis suav hais tias raug rau kev nyuaj siab corrosion cracking nyob rau hauv ib txwm kev pab cuam. Trace chromium los ntawm 0.04 mus rau 0.35% txhim kho pitting kuj nyob rau hauv chloride-cov kabmob puag ncig. Rau cov ntug hiav txwv dej thiab ntug dej hiav txwv raug pom zoo, ib zaj duab xis ntawm 15 µm los yog ntau dua nrog lub foob kom raug; txaws- cheeb tsam kev pabcuam thiab kev sib cuag nrog cov xov xwm tsis tu ncua hauv pH 4–9 ntau yam ua pov thawj rau cov yeeb yaj kiab tuab ntxiv rau kev tshuaj xyuas ib ntus.
Temper thiab Txheej Xaiv los ntawm Kev Pabcuam Ib puag ncig
Sab hauv tsev, kev tiv thaiv thiab cov rooj ua haujlwm: T6 nrog 10 µm Hom II zaj duab xis, ntshiab lossis dyed dub.
Sab nraum zoov architectural trim, pH 4-9 chemical media: T6 nrog 15-25 µm zaj duab xis thiab dej kub los yog npib tsib xee acetate sealing.
Marine thiab offshore hardware: T6 nrog ib zaj duab xis tsawg kawg yog 20 µm, los yog hom III nyuaj anodizing qhov twg puas thiab ntsev tsuag ua ke.
Welded assemblies: tsim rau kwv yees li 15% lub zog txo nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam, ces re-anodize lub weld hauv zos los yog siv ib tug epoxy los yog polyester txheej los txhim kho lub barrier txheej.
Machined precision thav duab: T651 kom flatness thiab ntev nyob rau hauv kam rau ua tom qab milling.
Cov lus nug nquag
Q: Yuav ua li cas "sib npaug" txhais tau tias nyob rau hauv ib lub vaj huam sib luag aluminium?
Nws txhais tau tias ob txhais ceg ntawm L-profile muaj qhov dav thiab tuab tib yam, yog li cov seem yog sib luag thiab tuaj yeem taw qhia yam tsis xav txog ib ceg ntev lossis ceg luv. Lub kaum sab xis tsis sib xws, muaj ob txhais ceg ntawm qhov dav sib txawv.
Q: Puas yog anodizing txo lub zog ntawm 6061 lub kaum ntse ntse?
Cov txheej txheem anodic tsis hloov lub zog tensile ntawm lub substrate, tab sis oxide txheej nws tus kheej yog ib qho nyuaj thiab nkig. Kev tsim, khoov thiab nruj-vim txoj haujlwm yuav tsum ua kom tiav ua ntej anodizing, vim hais tias khoov ib coated profile tuaj yeem craze zaj duab xis thiab nthuav tawm cov hlau ci.
Q: Kuv puas yuav tsum qhia T6 lossis T651?
Xaiv T6 rau cov txheej txheem dav dav uas cov khoom raug txiav kom ntev thiab bolted. Xaiv T651 thaum twg lub kaum sab xis yuav raug machined, drilled nyob rau hauv cov chaw ntev los yog welded rau hauv ib tug precision sib dhos, vim hais tias qhov kev nyuaj siab -relieved temper txwv tsis pub txav txav tom qab cov khoom raug tshem tawm.
Q: Ntev npaum li cas cov anodic zaj duab xis yuav tsum tau siv rau sab nraum zoov?
Rau feem ntau sab nraum zoov thiab architectural luag hauj lwm ib tug kaw zaj duab xis ntawm 15 µm los yog ntau tshaj yog txaus. Marine, offshore thiab industrial cua hu rau 20-25 µm, los yog Hom III nyuaj anodizing thaum puas kuj yuav tsum tau.
Q: 6061 lub kaum ntse ntse tuaj yeem welded?
Yog lawm. Nws yog welded nrog 4043 los yog 5356 muab tub lim, thiab tshav kub - cuam tshuam cheeb tsam poob roughly 15% ntawm nws lub zog nyob rau hauv T6 temper. Nrhiav cov welds kom deb ntawm qhov siab tshaj - cheeb tsam kev ntxhov siab thiab rov qab tiv thaiv corrosion ntawm thaj chaw weld tom qab, txij li kev vuam ua rau cov yeeb yaj kiab anodic hauv zos.
Q: Puas tuaj yeem hnav lossis tsis muaj xim anodic zaj duab xis raug tshem tawm thiab rov ua dua tshiab?
Yog lawm. Cov txheej yog muab tshem tawm hauv alkaline lossis acid stripping da dej, qhov profile yog desmutted, thiab tshiab anodizing yog siv. Lub substrate poob ib qho me me ntawm thickness nrog txhua lub voj voog, yog li rov qab stripping feem ntau txwv rau nyias - ntu phab ntsa.
