Vim li cas 5083 Aluminium Sheets rau Nkoj Nkoj Nkoj?
Cov nkoj nuv ntses ua haujlwm nyob rau hauv ib qho ntawm cov khoom siv uas xav tau tshaj plaws: kev raug dej hiav txwv mus tas li, rov cuam tshuam los ntawm nthwv dej thiab chaw nres nkoj, thiab ntau xyoo ntawm kev pabcuam txuas ntxiv. Alloy 5083 (AA5083, EN AW-5083) yog ib qho txhuas-magnesium alloy tsim tshwj xeeb rau lub luag haujlwm no. Nws ua ke ntawm lub zog siab, zoo heev seawater corrosion kuj thiab zoo weldability tau ua rau nws lub neej ntawd xaiv rau hulls, decks, cabins thiab cov tswv cuab ntawm ob qho tib si coj mus muag thiab ua si nuv ntses nkoj.
Cov Khoom Tseem Ceeb ntawm Marine-Qib 5083
Siab zog, tsawg ntom- ntawm txog 2.66 g / cm3, 5083 muab cov khoom sib dua, uas txhais tau hais tias kev ceev zoo dua, them nyiaj thiab roj kev lag luam ntau dua li cov hlau lossis GRP lwm txoj hauv kev.
Superior corrosion kuj- cov hlau tiv taus ntev -lub sij hawm raug dej ntsev thiab tiv thaiv kev ntxhov siab corrosion tawg hauv cov huab cua hauv hiav txwv, txawm tias cov txheej txheem oxide tiv thaiv raug khawb.
Weldability zoo heev- welded nrog 5183 lossis 5356-hom muab tub lim, cov pob qij txha khaws feem ntau ntawm cov niam txiv lub zog hlau, ua kom muaj zog, tsis muaj dej tsis zoo.
Zoo qis -kub toughness– tseem ceeb rau cov nkoj nuv ntses hauv siab -latitude thiab txias- dej hauv av.

| 5083-H116 / H321 | Ntau dua lossis sib npaug rau 305 | Ntau dua lossis sib npaug li 215 | Ntau tshaj los yog sib npaug rau 10 | Welded hull plating hauv seawater |
Cov khoom muaj nqis sib txawv nrog cov tuab thiab kev tswj hwm ntawm cov qauv siv tau; Cov ntawv pov thawj cov ntaub ntawv pov thawj yuav tsum tau lees paub qhov kev txwv qhov xav tau rau txhua qhov kev txiav txim.
5083 vs Lwm yam Alloys siv hauv Nkoj Nkoj Tsev
| Alloy | Kev siv yam | Sau ntawv |
|---|---|---|
| 5083 | Cov kab mob, kab mob, kab mob, kab mob | Lub zog siab tshaj plaws ntawm cov marine 5xxx daim ntawv alloys |
| 5086 | Hull hauv qab, sab | Kev ua tau zoo sib xws, zoo heev tsim cov yam ntxwv |
| 5052 | Internal qauv, hatches, nkoj dej tshiab | Lub zog nruab nrab, zoo heev formability thiab weldability |
| 6061-T6 | Ncej, masts, reinforcement | Thaum tshav kub kub- kho tau cov qauv alloy, zoo machinability |
| 6063-T5/T6 | Gunwales, rails, trim seem | Extruded architectural duab nrog zoo nto tiav |
Xaiv Thickness thiab Temper los ntawm Nkoj Loj
Cov nkoj me me (hauv qab li 8 m) feem ntau siv 3-5 hli 5083 daim ntawv kom tsis txhob hnyav. Cov nkoj nuv ntses nruab nrab thiab loj feem ntau hais txog 5-10 hli rau lub nkoj hauv qab thiab sab plating kom tiv thaiv av thiab cuam tshuam, nrog 8-12 hli hauv keel thiab chine thaj chaw. Rau kev xaiv temper: O lossis H111 haum rau kev sib sau hnyav thiab stamping; H116 lossis H321 yog qhov zoo dua rau welded hull plating uas tseem nyob hauv kev pabcuam dej hiav txwv mus tas li; H24 muaj lub tiaj tiaj, ruaj khov vaj huam sib luag rau sab hauv bulkheads.
Fabrication, Welding thiab Supply Considerations
5083 tuaj yeem txiav, khoov, dov thiab welded nrog cov khoom siv hauv nkoj. Cov ntawv thov dej hiav txwv yuav tsum ua raws li cov txheej txheem vuam tau txais los ntawm kev faib cov koom haum xws li ABS, DNV, LR, BV lossis CCS, uas kuj suav nrog cov ntaub ntawv pov thawj. Thaum muab khoom, qhia meej alloy, temper, thickness, dav thiab yuav tsum tau daim ntawv pov thawj, thiab thov ib daim ntawv pov thawj cov ntaub ntawv xeem nrog txhua batch.
Cov lus nug nquag
Puas yog 5083 txhuas haum rau cov nkoj nuv ntses dej qab ntsev?Yog. 5083 yog marine-qib Al-Mg alloy nrog zoo heev tiv thaiv dej hiav txwv corrosion thiab kev ntxhov siab corrosion tawg, ua rau nws yog ib qho ntawm cov khoom siv dav tshaj plaws rau cov dej ntsev.
Qhov txawv ntawm 5083-O thiab 5083-H116 / H321 yog dab tsi?5083-O yog tag nrho annealed rau siab tshaj plaws formability, thaum H116 thiab H321 yog strain-hardened tempers nrog siab zog (yield siab tshaj 215 MPa) thiab yog tsim los kom nyob twj ywm corrosion resistant tom qab vuam, uas yog vim li cas lawv nyiam rau hull plating.
5083 puas tuaj yeem welded rau lwm yam txhuas alloys?Yog lawm, nrog rau kev xaiv muab tub lim tsim nyog, feem ntau yog 5183 lossis 5356. Rau cov pob qij txha tseem ceeb, cov txheej txheem vuam yuav tsum tsim nyog thiab cov khoom HAZ suav nrog hauv kev tsim.
Dab tsi thickness ntawm 5083 yog siv rau hull plating?Hom kab plating rau cov nkoj nuv ntses yog li ntawm 3-5 hli rau cov khoom siv me me mus rau 6-10 hli rau cov nkoj loj thiab nruab nrab, nrog rau qhov hnyav dua ntawm keels thiab chines.
Cov ntaub ntawv pov thawj dab tsi tuaj yeem muab nrog 5083 nplooj ntawv?Daim ntawv pov thawj zeb xeem, EN 10204 3.1-cov ntaub ntawv tshuaj xyuas thiab cov ntawv pov thawj hauv zej zog (ABS, DNV, LR, BV, CCS) tuaj yeem muab tau raws li kev thov.
