Thaum muab cov khoom siv rau kev tsim khoom hauv nkoj thiab kev lag luam hauv hiav txwv hnyav, kev qhia txog qhov tseeb aluminium alloy tsuas yog ib nrab ntawm txoj haujlwm. Kev qhia qhov tseeb yog qhov ua kom muaj kev nyab xeeb ntawm cov qauv thiab tiv thaiv kev tsim khoom tsis zoo.
Ntawm 5000-series alloys, 5083 yog tus huab tais tsis muaj kev sib cav ntawm kev siv dej hiav txwv. Kev xaiv qhov tsis ncaj ncees lawm tuaj yeem ua rau muaj kev tawg loj heev thaum lub sijhawm khoov lossis tsis lees paub los ntawm cov koom haum marine classifications.
Txawm hais tias ob qho tib si muaj nyob rau tib yam 5083 tshuaj lom neeg muaj pes tsawg leeg, lawv txoj kev ua thiab cov ntawv thov zoo sib txawv heev. Ntawm GNEE, peb tsim thiab muab cov ntawv pov thawj marine- qib txhuas phaj. Hauv phau ntawv qhia no, peb rhuav tshem qhov sib txawv ntawm qhov tseeb ntawm 5083 H111 thiab H112 los pab koj txiav txim siab yuav khoom rau koj qhov project.
5083 Marine Qib Aluminium Phaj yog dab tsi?
Cov5083 aluminium ntawvyog ib qho uas tsis yog -kub- kho tau alloy muaj 4.0% mus rau 4.9% magnesium. Nws yog lub ntiaj teb- muaj koob npe nrov rau nws qhov kev ua tau zoo tshwj xeeb hauv ib puag ncig huab cua. Nws muaj lub zog siab tshaj plaws ntawm tag nrho cov uas tsis yog- cua sov- kho cov alloys, zoo weldability, thiab kev tiv thaiv tsis pub dhau dej hiav txwv thiab muaj tshuaj lom neeg corrosion.
Vim tias nws tsis tuaj yeem muaj zog los ntawm kev kho cua sov (xws li 6000 series), nws lub zog tau ua tiav los ntawm kev ua haujlwm txias (txias ua haujlwm) thiab tshwj xeeb thermal stabilization. Qhov no yog qhov "H" temper designations tuaj rau hauv kev ua si.
5083 H111 Aluminium Phaj
5083 H111 txhuas phaj yog ib qho ntawm cov khoom siv dav tshaj plaws rau cov nkoj nkoj hiav txwv.
Kev Ua Haujlwm: H111 npau taws txhais tau hais tias lub phaj tau ua tiav tag nrho (softened) thiab tom qab ntawd raug rau me ntsis ntawm cov tawv nqaij tawv (txias ua hauj lwm) thaum ua haujlwm xws li ncab lossis qib.
Vim li cas ho xaiv nws? H111 temper muab qhov zoo sib npaug. Nws muaj lub zog me ntsis siab dua li qhov muag muag "O" temper, tab sis nws khaws cov ductility loj. Yog tias koj cov txheej txheem tsim khoom yuav tsum tau ua kom yooj yim rotary dabtsi yog khoov, stamping, lossis curving (xws li shaping lub hull ntawm lub nkoj), koj yuav tsum yuav 5086 lossis 5083 H111. Nws yuav tsis tawg los yog tawg nyob rau hauv loj dabtsi yog khoov kev nyuaj siab.
5083 H112 Marine Aluminium Sheet
5083 H112 txhuas ntawv yog feem ntau cov khoom siv.
Kev Ua Haujlwm: H112 temper qhia tias "raws li fabricated" xeev. Nws yog feem ntau ua tiav los ntawm kev kub dov. Tsis txhob txhob txwm ua haujlwm txias lossis annealing siv los tswj nws cov hardness, tab sis muaj kev nruj, lav yam tsawg kawg nkaus cov cuab yeej cuab tam.
Vim li cas ho xaiv nws? H112 yog tus nqi siab heev - ua haujlwm zoo thiab ua suab nrov. Nws yog tsim los rau cov ntawv thov uas lub phaj yuav siv ncaj los yog raug khoov tsawg heev. Yog tias koj tab tom tsim lub tiaj tus bulkheads, diesel cav pedestals, tiaj lawj flooring, los yog cov qauv thav duab, 5083 H112 yog qhov kev xaiv zoo tshaj.
Tshuaj muaj pes tsawg leeg ntawm 5083 Aluminium Alloy
Txij li H111 thiab H112 tsuas yog temper variations, lawv qhia tib yam tshuaj pleev ib ce. GNEE nruj me ntsis tswj cov tshuaj txwv kom ntseeg tau tias DNV / ABS daim ntawv pov thawj ua raws:
| Element | Cov ntsiab lus feem pua (%) |
| Magnesium (Mg) | 4.00 – 4.90 |
| Manganese (Mn) | 0.40 – 1.00 |
| Chromium (Cr) | 0.05 – 0.25 |
| Silicon (Si) | Max 0.40 |
| Hlau (Fe) | Max 0.40 |

Mechanical Properties: 5083 H111 vs 5083 H112
Hauv qab no yog chav txheem -kub txhua yam ntaub ntawv rau ob qho tib si tempers. (Ceeb toom: 5083 txhuas daim hlau yuav tsum tsis txhob raug kuaj los yog ua haujlwm nyob rau hauv ib puag ncig tas li tshaj 65℃/ 150℃F, vim qhov kub thiab txias ua rau magnesium nag lossis daus thiab kev ntxhov siab corrosion tawg).
5083 H111 Mechanical Properties
Tensile zog:275 - 350 MPa
Yield Strength (pov thawj Stress):Min 125 MPa (feem ntau nyob ib ncig ntawm 145 MPa)
Elongation:Min 16% (Feem ntau mus txog 20-23% nyob ntawm thickness)
Hardness:~ 75 HV
5083 H112 Mechanical Properties
Tensile zog:270 - 340 MPa
Yield zog:Min 125 MPa
Elongation:Tsawg tshaj 12%
Hardness:~ 65 - 75 HB
(Xaiv: H111 muaj qhov zoo dua elongation, ua rau nws qhov kev xaiv zoo tshaj rau kev khoov).
Nkag siab txog General "H" Temper System
Txhawm rau pab peb cov neeg yuav khoom B2B nkag siab txog cov lus qhia tshwj xeeb ntawm txhuas, ntawm no yog qhov nrawm nrawm ntawm "H" (Strain Hardened) temper system:
- H1 (Strain Hardened nkaus xwb): Lub phaj txias- ua haujlwm kom ncav cuag lub zog uas yuav tsum tau ua yam tsis muaj kev kho cua sov ntxiv. (piv txwv li, H18 yog tag nrho nyuaj, nkig heev, thiab tsis haum rau khoov).
- H2 (Strain Hardened & Partially Annealed): Cov hlau yog txias- ua haujlwm dhau los ntawm qhov xav tau lub zog, tom qab ntawd ib nrab annealed kom soften nws me ntsis thiab txhim kho ductility.
- H3 (Strain Hardened & Stabilized): Cov hlau yog txias- ua haujlwm thiab tom qab ntawd raug rau qis- qhov kub thiab txias kho kom ruaj khov rau nws cov khoom siv kho tshuab. Qhov no yog qhov tseem ceeb rau magnesium-alloyed aluminium zoo li 5083 los tiv thaiv hnub nyoog- softening ntawm chav tsev kub.
- 5083 H116& H321 (The Ultimate Marine Tempers): Cov no yog cov tempers tshwj xeeb rau 5083 thiab 5086 alloys. Lawv tau ua tiav tshwj xeeb los muab qhov siab tshaj plaws tiv thaiv intergranular thiab exfoliation corrosion nyob rau hauv tob - hiav txwv, hnyav dej ntsev ib puag ncig.
Bending Guidelines rau 5083 Aluminium Phaj
dabtsi yog khoov 5083 txhuas yuav tsum tau txuam nrog txoj cai temper nrog rau txoj cai tooling.
- Tsis Txhob Khoov: Siab- hardness tempers zoo li H18 lossis H38 yuav tawg tam sim ntawd thaum khoov nruj.
- Kev nyab xeeb rau khoov: O (Annealed), H111, H112, H32.
- Qhov Zoo Tshaj Plaws: Thaum khoov ib daim ntawv 5083 H111 marine aluminium, nco ntsoov hwm qhov tsawg kawg nkaus khoov vojvoog. Rau cov txheej txheem thicknesses, ib lub vojvoog khoov sab hauv ntawm 1.5t rau 2.5t (qhov twg 't' yog phaj tuab) raug pom zoo los tiv thaiv qhov tawg.
Vuam 5083 Shipbuilding Aluminium Phaj
Ob lub H111 thiab H112 tempers muab qhov zoo tshaj plaws weldability. Vim lawv tsis kub heev-kho, tshav kub- cuam tshuam cheeb tsam (HAZ) khaws cia ib tug loj npaum li cas ntawm lub hauv paus hlau lub zog.
Kev Pom Zoo Rau Cov Hlau Hlau: Rau cov ntawv thov dej hiav txwv, ib txwm siv ER5183 lossis ER5356 muab tub lim kom phim cov ntsiab lus magnesium thiab tiv thaiv galvanic corrosion ntawm qhov sib koom ua ke.
