5083 Aluminum Plate for Tanker & LNG Applications

5083 aluminum plate is magnesium-alloyed with good weldability, corrosion resistance, and fabrication performance. Its moderate strength makes it well suited for liquid tanker manufacture—especially for low-temperature media (e.g., LNG) and coastal/salt-spray environments in long-haul service—which is why it is one of the preferred materials for aluminum tankers.

A tanker body comprises side panels, baffles, manholes, and other parts. The shell typically uses 5083-H111 plate, while the tank lid and internal partitions use softer 5083-O plate for easier bending, helping ensure sealing and structural strength.

For tanker use, plate width is generally below 2.2 m, with common thicknesses of 5, 6, 7, and 8 mm. A complete shell usually requires 4–6 plates welded together, so welding performance and joint elongation are critical to structural integrity and leak-tightness.

Features of 5083 Aluminum Plate for Oil Tanker

Excellent Low-Temperature Toughness: Performs reliably at LNG temperatures (-162 °C), maintaining strength and ductility, ideal for cryogenic transport and storage.

Outstanding Corrosion Resistance: High magnesium content provides strong resistance to salt spray and marine environments, lowering maintenance costs.

Good Weldability: Supports gas welding, TIG/MIG, and spot welding with high joint elongation and tight, durable seams.

Wide Plate Advantage: Up to 2600 mm wide plates reduce longitudinal welds and improve tank integrity.

Lightweight Design: Higher strength-to-weight ratio than steel, reducing vehicle weight and increasing payload capacity.

High-Temperature Note: Strength drops at >65 °C; not recommended for asphalt or hot-medium tankers. Consider 5454 aluminum plate for such applications.

Recyclable & Sustainable: Fully recyclable, supporting green manufacturing and lifecycle cost efficiency.

Tanker Plate Selection Guide (5182 | 5083 | 5454 | 5754)

For ADR hazardous goods at ambient–medium temperature, choose 5182 Aluminum plate.

For cryogenic/LNG or coastal salt-spray environments, choose 5083 tanker plate.

For long-term medium–high temperature or insulated cargo, choose 5454 Aluminum plate.

For general welded structures or food/personal care applications, choose 5754 Aluminum plate.

Durability and Low Maintenance Costs: The Economic Benefits of Aluminum Tankers

First, aluminum alloy tank trucks excel in safety, boasting a solid accident record. Their low center of gravity enhances braking stability, and the use of non-combustible materials reduces the risks of sparks and static electricity buildup. Additionally, the lighter weight of aluminum alloy bodies allows for higher effective payloads, which can decrease the number of transport trips and improve return on investment.

In terms of fuel efficiency, aluminum alloy tank trucks help lower carbon dioxide emissions, making them more environmentally friendly. Their strong corrosion resistance ensures a lifespan of 15 to 20 years, while maintenance costs remain low, as they do not require painting and have a durable appearance that is easy to clean. Finally, the high recyclability of aluminum provides additional revenue after the truck is decommissioned.

FAQ — 5083 Aluminum Plate for Tank Trucks

1. Can 5083 be used for cryogenic or LNG tankers?

Yes. 5083 maintains strength and toughness down to LNG temperatures (≈ −162 °C), making it suitable for cryogenic transport and storage tanks. Compared with many steels, it offers lower weight with good formability and weldability for tanker fabrication.

2. How does 5083 perform in coastal or salt-spray environments?

5083 is a high-magnesium alloy with strong resistance to salt spray and marine atmospheres. It fits coastal, port, and chemical routes and helps reduce long-term corrosion maintenance.

3. What should I pay attention to when welding the shell?

Use ER5183 (preferred) or ER5356 filler, control heat input and interpass temperature, and clean oxide/oil before welding. Ensure proper shielding to avoid porosity and cracking and verify joints via NDT as required (PT/RT/UT).

4. Which tempers are commonly used for tanker parts?

Typical mapping: 5083-H111 for shells; 5083-O for heads, baffles, bulkheads, and manhole covers; 5083-H321 for selected high-stress parts. Choose temper by balancing strength, ductility, and forming needs.

5. When should I choose 5083 vs. 5454?

Choose 5083 for cryogenic/ambient media and marine routes where ductility and corrosion resistance are key. For long-term hot media (e.g., asphalt/insulated cargo), 5454 is usually preferred due to better high-temperature stability.

6. MOQ and samples?

Mixed specifications are supported. Samples can be supplied with measurement reports and EN 10204 3.1 MTC; special cutting and kit supply are quoted by process.

7. Lead time, packing, and documents?

Typical lead time is 5–7 days for samples and 2–3 weeks for bulk orders, with options for expedited or partial shipments. Export packing uses PE film plus crate/pallet; documents can include EN 10204 3.1, COO, and REACH/RoHS upon request.
