Ob Tsev Neeg Alloy, Ob Txoj Kev Tsim Qauv
5052 belongs rau tsev neeg 5xxx, qhov twg magnesium yog lub ntsiab alloying ntxiv thiab lub zog los ntawm kev ua hauj lwm hardening . 6061 belongs rau 6xxx tsev neeg, qhov twg magnesium thiab silicon tsim magnesium silicide, yog li cov alloy teb rau kev kho cua sov thiab kev laus laus. Qhov sib txawv ntawm ib qho metallurgical no piav qhia yuav luag txhua qhov sib txawv ntawm ob qib: yuav ua li cas lawv muab, lawv koom li cas, lawv siv tshuab li cas thiab qhov twg lawv siv.
Chemistry thiab Composition Limits
| Lub ntsiab | 5052 (NWS A95052) | 6061 (NWS A96061) |
|---|---|---|
| Magnesium | 2.2-2.8% | 0.8-1.2% |
| Silicon | 0.25% max | 0.40-0.8% |
| Chromium | 0.15-0.35% | 0.04-0.35% |
| Tooj | 0.10% max | 0.15-0.40% |
| Manganese | 0.10% max | 0.15% max |
| Hlau | 0.40% max | 0.7% max |
Cov kev txwv no ua raws li cov ntawv sau npe luam tawm hauv ASTM B209 thiab EN 573-3. Qhov sib ntxiv ntawm chromium hauv 5052 txhim kho kev tiv thaiv kev ntxhov siab, thiab cov tooj liab hauv 6061 yog qhov tso cai rau cov hlau kom ncav cuag T6 cov khoom thaum tseem ua rau nws pom muaj zog dua li cov ntawv tsis muaj lossis 3xxx daim ntawv.
Temper Muaj
5052 yog nkag rau hauv strain- hardened tempers thiab nyob rau hauv lub annealed mob: O, H32, H34, H36, H38 thiab H112. Nws tsis tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, yog li daim ntawv cov khoom raug kho los ntawm qhov txo qhov txias ntxiv nrog rau kev kho kom ruaj khov . 6061 yog muab rau hauv O, T4, T6 thiab, rau phaj, T651, qhov twg T651 stretch ua haujlwm txo qis hauv kev ntxhov siab rau machining. Tus neeg yuav khoom hais txog 5052-H24 lossis 6061-H32 tab tom thov kom npau taws uas tsis muaj nyob hauv cov rooj sau npe.
Mechanical Behavior thiab Formability
Nyob rau hauv lub tempers feem ntau pauv, 5052-H32 yog ib tug nruab nrab-lub zog, siab ductile daim ntawv nrog zoo heev qaug zog tus cwj pwm, thaum 6061-T6 yog ib tug muaj zog cov ntaub ntawv uas nrog qis elongation. Cov nqi luam tawm zoo tshaj qhov chaw 5052-H32 tensile lub zog nyob rau hauv thaj tsam ntawm 210 txog 260 MPa thiab 6061-T6 tensile lub zog nyob ib ncig ntawm 310 MPa nrog lub zog tawm los ze 276 MPa. Qhov tshwm sim yog tias 5052 lees txais nruj khoov radii thiab sib sib zog nqus sib sau ua ke, qhov 6061-T6 feem ntau yog khoov rau hauv lub vojvoog dav lossis tsim hauv T4 mob thiab hnub nyoog tom qab. Sheared npoo ntawm 6061-T6 yog qhov yooj yim dua rau kev tawg thaum lub sij hawm tsim hnyav, yog li lub kaum nyem nyem thiab khoov radii yuav tsum tau npaj rau hauv kev tsim tuag.
Corrosion, Vuam thiab Machining
5052 muaj qhov zoo tshaj plaws corrosion kuj ntawm ob thiab yog tus qauv xaiv rau marine thiab ntug hiav txwv fabrications; nws yog welded nrog 5356 los yog 5556 muab tub lim thiab ua kom muaj zog sib koom ua ke yam tsis muaj kev tshaj tawm -weld heat treatment. 6061 muaj kev tiv thaiv zoo rau atmospheric corrosion tab sis cov ntsiab lus tooj liab ua rau nws yooj yim dua rau qee qhov chaw, thiab cov pob qij txha welded poob lub zog nyob rau hauv tshav kub-tshwj tsis yog qhov seem yog re-. Ntawm machining, qhov qeb duas rov qab: 6061-T6 tshuab huv si nrog zoo nti tswj thiab yog lub neej ntawd rau machined brackets, manifolds thiab twj twj tso kua mis, thaum 5052 yog gummy, prone rau built-up ntug thiab feem ntau xav tau ntse tooling, siab dua rake kaum thiab siab zoo lubrication yog cov {5052 grades ib txwm muaj; 5052 xav tau lub zog ntau dua hauv welded marine qauv.
Xaiv Phau Ntawv Qhia los ntawm Daim Ntawv Thov
Xaiv 5052 rau roj tso tsheb hlau luam, marine panels, siab hlab ntsha, txoj kev tanker sheeting, khoom vaj huam sib luag, ntawv hlau enclosures, ducting thiab architectural ua hauj lwm qhov twg formability thiab ntsev kuj dominate. Xaiv 6061 rau cov qauv kev sib txuas, cov phaj sib dhos, lub tsheb kauj vab thav duab, lub tog raj kheej pneumatic, jigs thiab fixtures, tsheb lub cev thiab cov dab dej kub uas muaj zog, qhov ruaj khov tom qab machining thiab anodising zoo dominate. Qhov twg ib feem yuav tsum yog ob qho tib si welded thiab muaj zog, qhov kev sib haum xeeb ib txwm yog 5083 lossis 6061 nyob rau hauv T4 mob nrog post-weld aging es tsis yuam ib qib ua ob txoj haujlwm.
Cov lus nug nquag
Q:5052 puas tuaj yeem kho cua sov kom muaj zog?
A: Tsis yog. 5052 yog ib qho uas tsis yog- cua sov- kho tau alloy; lub zog los ntawm kev ua hauj lwm hardening, yog li siab dua tempers xws li H34 los yog H38 yuav tsum tau txiav txim los ntawm lub zeb.
Q:Qib twg zoo dua rau anodising?
A: 6061 feem ntau tsim cov anodic zaj duab xis huv si vim tias nws tsis muaj magnesium ntxhib- cov theem nplua nuj uas tuaj yeem ua rau muaj xim sib txawv . 5052 anodizing zoo tab sis cov tsos zoo li nruj dua ntawm temper uniformity.
Q:Puas yog 5052 muaj zog dua 6061?
A: Tsis yog. Nyob rau hauv tempers feem ntau muab, 6061-T6 yog kom meej meej cov khoom muaj zog; 5052-H32 yog xaiv rau ductility thiab corrosion kuj tsis yog lub zog.
Q:Ob lub alloys puas tuaj yeem welded rau ib leeg?
A: Aluminium alloys ntawm cov tsev neeg sib txawv tuaj yeem welded nrog 5xxx muab tub lim, tab sis kev sib koom ua ke lub zog thiab kev coj tus cwj pwm yuav tsum tau lees paub los ntawm cov txheej txheem kev tsim nyog rau kev tsim tshwj xeeb.
Q:Qhov twg tus nqi ntau dua?
A: 6061 feem ntau nqa tus nqi siab dua ib kilogram vim nws cov alloying ntxiv thiab kev kho cua sov; 5052 yog tus nqi qis dua - daim ntawv engineering.
Q:Qhov kev pabcuam siab tshaj plaws yog dab tsi?
A: Ob lub alloys feem ntau khaws cia qis dua li ntawm 150 degrees Celsius rau ntev - kev pabcuam kev ua haujlwm, txij li qhov kub siab dua pib soften 5052 thiab overage 6061.
