Chemical Composition thiab Basic Specifications
Alloy 5052 thiab alloy 5083 ob leeg koom nrog 5xxx series, tsis yog- tshav kub-kho tau txhuas-magnesium tsev neeg, thiab ob qho tib si tau ntxiv dag zog los ntawm cov kua nplaum thiab cov tawv tawv tawv. Qhov sib txawv tseem ceeb yog cov ntsiab lus magnesium, thiab qhov sib txawv ntawm ib leeg yuav luag txhua qhov sib txawv ntawm ob qib.
| Element | 5052 (ntau npaum li cas) | 5083 (ntau feem pua) |
|---|---|---|

Vim hais tias magnesium yog cov khoom tseem ceeb- kev daws teeb meem hauv tsev neeg no, qhov siab dua magnesium qib ntawm 5083 ua kom pom tseeb zog dua thiab zoo dua tiv thaiv dej hiav txwv. Manganese thiab chromium ntxiv nyob rau hauv ob qib tswj cov qauv nplej thiab txo qhov cuam tshuam rau kev ntxhov siab corrosion cracking.
Mechanical Properties thiab Tempers
Tsis yog alloy teb rau nag lossis daus hardening, yog li cov khoom yog tsim los ntawm strain hardening thiab stabilized tempers. Cov khoom siv feem ntau yog H32 rau 5052 thiab H321 lossis H116 rau 5083.
| Cov khoom, cov nqi raug | 5052-H32 | 5083-H321 |
|---|---|---|
| Lub zog tensile | Txog 230 MPa | Txog 317 MPa |
| Yield zog, 0.2 feem pua offset | Txog 195 MPa | Txog 228 MPa |
| Elongation | Kwv yees li 12 feem pua | Kwv yees li 12 feem pua |
| Qhov ntom | Txog 2.68 grams ib cubic centimeter | Txog 2.66 grams ib cubic centimeter |
| Hom hardness | Nruab nrab | Siab dua |
Qhov ua tau zoo yog tias 5083 yog kwv yees li ib feem peb muaj zog dua 5052 ntawm qhov ntsuas sib piv, uas tso cai rau cov ntu nyias rau tib lub nra. Thinner seem txuag qhov hnyav tab sis txo qhov nruj, yog li kev txiav txim siab hloov pauv yuav tsum xav txog deflection thiab buckling, tsis muaj zog ib leeg.
Formability, Weldability thiab Corrosion Cwj Pwm
Formability yog qhov twg 5052 yeej meej. Nws cov ntsiab lus magnesium qis thiab qis zog ua rau nws muaj peev xwm khoov me me thiab cov lus teb sib sib zog nqus zoo dua, yog li khoov brackets, enclosures, roj tso tsheb hlau luam thiab cov vaj huam sib luag tsim feem ntau yog teev nyob rau hauv 5052. Alloy 5083 yog ib qho nyuaj, tsis tshua muaj ductile thiab feem ntau ua rau tawg ntawm nruj khoov radii, thiab nws yog ib txwm siv qhov chaw thauj khoom hnyav dua li qhov yuav tsum tau ua.
Ob lub alloys tau yooj yim fusion welded thiab yog nrov rau welded fabrications . 5083 yog qhov kev xaiv muaj zog rau cov qauv welded vim tias thaj tsam weld khaws cov feem ntau ntawm niam txiv lub zog hlau. Filler hlau los ntawm aluminium- tsev neeg magnesium, xws li ER5183 thiab ER5356, feem ntau yog siv los ua kom haum rau lub zog thiab tus cwj pwm corrosion. Welded 5xxx lub rooj sib txoos yuav tsum zam kom tsis txhob muaj cua sov ntau dhau, uas tuaj yeem ua rau cov khoom siv nyob rau hauv qhov vuam kub- thaj tsam cuam tshuam.
Corrosion kuj zoo heev nyob rau hauv ob qib nyob rau hauv marine thiab industrial atmospheres. Alloy 5083 khaws qhov ntsuas tau zoo hauv cov dej tsis tu ncua, chloride - kev pabcuam nplua nuj. Ib qho kev txwv tshwj xeeb yog siv rau 5083: qhov ntev ntev ntawm qhov kub siab tshaj li 65 degrees Celsius tuaj yeem ua rau cov qoob loo nce qib - ciam teb magnesium theem thiab ua rau muaj kev cuam tshuam rau kev ntxhov siab corrosion tawg, yog li siab - qhov kev pabcuam kub hu rau qib stabilized lossis sib txawv alloy nkaus.

Cov qib no piav qhia txog qhov tseem ceeb ntawm cov alloys tib yam, txhais los ntawm kev sib piv cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Qhov sib txawv me me tseem tuaj yeem muaj nyob rau hauv temper designation, kam rau ua thiab tso cai impurity txwv, yog li kev yuav khoom yuav tsum nco ntsoov hais txog lub teb chaws tus qauv lossis qib uas yuav tsum tau ua raws li cov ntaub ntawv xa tawm.
Qhov twg qhov kev xaiv thib peb yog qhov muaj txiaj ntsig, alloy 5754 zaum ntawm ob, muab kev tiv thaiv corrosion zoo dua thiab kev tsim dua li 5052 nrog lub zog ze rau nws, thiab nws tau txais dav hauv European qauv thiab kev siv thauj khoom.

Ob lub ntsiab lus lag luam tsim nyog tau txais kev saib xyuas. Alloy 5083 yog tus nqi hwm tshaj 5052, yog li kev qhia nws tsis muaj lub zog lossis marine corrosion justification ntxiv tus nqi tsis muaj txiaj ntsig. Hauv lwm qhov kev taw qhia, hloov 5052 rau 5083 hauv daim ntawv thov txheej txheem tuaj yeem txo qis kev nyab xeeb thiab yuam kom rov tsim dua ib zaug cov duab kos mus txog kev tsim.
Cov lus nug nquag
Q: Dab tsi yog qhov txawv ntawm 5052 thiab 5083?
Alloy 5083 muaj kwv yees li ob zaug ntawm magnesium ntawm 5052, uas ua rau nws muaj zog thiab corrosion resistant nyob rau hauv seawater, thaum 5052 yog ntau formable, yooj yim rau khoov thiab tsis tshua kim.
Q: Puas yog 5083 sib npaug rau 5052?
Lawv muaj feem cuam tshuam tab sis tsis sib hloov. Ob leeg yog txhuas-magnesium alloys nrog zoo weldability, tsis tau lub zog thiab formability sib txawv yog loj txaus uas ib tug hloov pauv tsim margins.
Q: Cov alloy twg zoo dua rau kev siv marine?
Alloy 5083 yog tus qauv marine qib rau hulls, decks thiab superstructures vim nws muaj zog dua thiab superior tiv thaiv chloride nres. Alloy 5052 yog siv rau kev sib tw marine fittings thiab tsim qhov chaw.
Q: 5083 puas tuaj yeem siv rau ntawm qhov kub siab?
Kev pabcuam txuas ntxiv yog feem ntau txwv rau li 65 degrees Celsius. Saum toj no, kev raug ncua ntev tuaj yeem ua rau cov qoob loo nce qib - ciam teb magnesium theem thiab ua rau muaj kev ntxhov siab corrosion tawg.
Q: Yuav ua li cas yog ob lub alloys welded?
Ob qho tib si weld zoo los ntawm cov pa roj inert txoj kev siv txhuas-magnesium muab tub lim xws li ER5183 lossis ER5356. Alloy 5083 tuav ntau zog nyob rau hauv welded mob, uas yog vim li cas nws dominates welded marine lug.
Q: Qhov twg alloy anodizes zoo dua?
Alloy 5052 siv anodizing ntau uniformly thiab ua kom pom tseeb, ci dua tiav. Alloy 5083 tsim ib qho tsaus me ntsis thiab tsis tshua muaj pob tshab anodic txheej vim nws cov ntsiab lus magnesium thiab manganese ntau dua.
