What is the difference between H116 and H321 temper for marine aluminum?

Both H116 and H321 are stress-corrosion resistant tempers specified for marine use. H116 is strain-hardened and meets specific requirements for exfoliation corrosion resistance (ASTM G66, Grade PB or better). H321 is stabilized after strain hardening through thermal treatment. For most marine hull applications, H116 is preferred as it provides better intergranular and exfoliation corrosion resistance in high-magnesium alloys like 5083.

Do you provide DNV, BV, or ABS mill test certificates with every order?

Yes. Every marine grade plate we deliver includes original mill test certificates (MTC) from the producing mill, certified by the requested classification society (DNV-GL, Bureau Veritas, ABS, or Lloyd's Register). The MTC includes chemical composition, mechanical properties, and any additional testing results.

What is the minimum order quantity for marine grade aluminum plate?

Our standard MOQ for marine grade plate is 5 tons per alloy/temper/thickness combination. For standard sizes of 5083-H116, we maintain rolling stock and can offer smaller quantities from 1 ton. For non-standard dimensions or thicknesses above 50mm, mill production runs typically require 10-20 tons minimum.

Can you supply custom-cut marine plate to shipyard cutting plans?

Yes. We offer precision plasma and waterjet cutting services. If you provide your cutting plans (DXF/DWG files), we can nest and cut plates to your exact specifications before shipping. This reduces waste at the shipyard and speeds up fabrication.

How does 5083 marine plate perform in welded joints?

5083 is one of the best aluminum alloys for welding. When welded with 5183 or 5356 filler wire using MIG or TIG methods, the weld joint retains approximately 90% of the base metal's strength (275+ MPa tensile). The heat-affected zone reverts to an annealed condition but still provides adequate strength for marine structural applications.

Cov Lus Nug

Marine Aluminium FAQ

Dab tsi yog qhov txawv ntawm H116 thiab H321 temper rau marine txhuas?

Ob leeg H116 thiab H321 yog kev ntxhov siab-corrosion resistant tempers teev rau marine siv. H116 yog strain-hardened thiab ua tau raws li cov kev cai tshwj xeeb rau exfoliation corrosion kuj (ASTM G66, Qib PB lossis zoo dua). H321 yog stabilized tom qab strain hardening los ntawm thermal kho. Rau feem ntau marine hull daim ntaub ntawv, H116 yog nyiam raws li nws muab zoo intergranular thiab exfoliation corrosion kuj nyob rau hauv high-magnesium alloys zoo li 5083.

Koj puas muab DNV, BV, lossis ABS daim ntawv pov thawj zeb kuaj nrog txhua qhov kev txiav txim?

Yog lawm. Txhua qib marine qib peb xa tuaj suav nrog daim ntawv pov thawj zeb xeem (MTC) los ntawm cov khoom tsim, tau lees paub los ntawm cov neeg thov kev faib tawm (DNV-GL, Bureau Veritas, ABS, lossis Lloyd's Register). MTC suav nrog cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lwm yam kev sim ntxiv (piv txwv li, kuaj ultrasonic rau daim hlau saum 12 hli).

Dab tsi yog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis rau marine qib aluminium phaj?

Peb tus qauv MOQ rau marine qib phaj yog 5 tons ib alloy / temper / thickness ua ke. Rau cov qauv loj ntawm 5083-H116 (8mm, 10mm, 12mm, 16mm, 20mm), peb tuav cov khoom dov thiab tuaj yeem muab cov khoom me me los ntawm 1 tuj. Rau qhov tsis-tus qauv qhov ntev lossis thicknesses siab tshaj 50mm, zeb ntau lawm sau feem ntau yuav tsum tau 10-20 tons yam tsawg kawg nkaus.

Koj puas tuaj yeem muab kev cai txiav marine phaj rau shipyard txiav cov phiaj xwm?

Yog lawm. Peb muab precision plasma thiab waterjet txiav cov kev pab cuam. Yog tias koj muab koj cov phiaj xwm txiav (DXF / DWG cov ntaub ntawv), peb tuaj yeem zes thiab txiav daim hlau rau koj cov lus qhia meej ua ntej xa khoom. Qhov no txo cov khib nyiab ntawm lub nkoj nkoj thiab ua kom cov khoom siv ceev. Kev pabcuam txiav-rau-loj ntxiv 5-7 hnub ua haujlwm rau lub sijhawm ua tus qauv.

5083 marine phaj ua haujlwm li cas hauv cov pob qij txha?

5083 yog ib qho zoo tshaj plaws aluminium alloys rau vuam. Thaum welded nrog 5183 lossis 5356 muab tub lim siv MIG lossis TIG txoj kev, qhov sib koom ua ke khaws cia kwv yees li 90% ntawm lub hauv paus hlau lub zog (275 + MPa tensile). Lub tshav kub-cuam tshuam cheeb tsam (HAZ) rov qab mus rau ib qho annealed (O) temper condition tab sis tseem muab lub zog txaus rau marine structural applications. Peb pom zoo tom qab-weld soj ntsuam raws li kev faib pawg neeg yuav tsum tau.
