MC Aluminum’s marine-grade aluminum plates have been certified by multiple internationally recognized classification societies, including the Lloyd’s Register of Shipping (UK), American Bureau of Shipping (ABS), Det Norske Veritas (Norway), Nippon Kaiji Kyokai (Japan), and China Classification Society.

Driven by diversified vessel applications and advances in technology, demand in the shipbuilding industry has grown significantly. MC Aluminum’s 5083, 5086, and 6061 marine aluminum plates-known for their high strength and superior corrosion resistance-have gained strong market recognition and are now supplied in stable mass production batches.

5086 belongs to the 5000 series aluminum-magnesium alloys, with magnesium as its main alloying element. It contains slightly less magnesium than 5083, giving it excellent corrosion resistance, improved formability, and medium strength.

To meet various marine engineering requirements, MC Aluminum offers a full range of products, including plates, extrusions, and piping fittings:

Plates

• Thickness range: 3 mm ~ 50 mm

• Surface requirements: free from oil stains, roll marks, with protective film to prevent scratches

• Applications: ship hulls, decks, bulkheads, pontoons, and offshore platform panels

• Features: 5086 marine aluminum plates are available in widths up to 2650 mm, reducing weld seams and ensuring long-term structural integrity in marine environments. This significantly reduces maintenance and replacement costs due to corrosion. The common H116 temper, produced through specialized processes, further enhances resistance to stress corrosion cracking.

Extrusions

• Product types: structural sections, framing profiles, guide rails, gangway beams, etc.

• Applications: ship frameworks, porthole frames, deck railings

• Features: extrusion allows the manufacturing of complex cross-sections and hollow profiles, achieving both lightweight construction and enhanced structural stiffness. Using one-piece extrusions reduces welding requirements, increases production efficiency, and improves joint quality-ideal for building large and complex vessel structures.

• High dimensional precision, stable structural strength, and customizable complex profiles.

Piping and Fittings

• Specifications: seamless pipes, welded pipes, elbows, flanges, tees, etc.

• Applications: seawater transfer, cooling systems, ballast systems

• Features: Using piping and fittings made of the same or compatible 5086 aluminum alloy prevents galvanic corrosion from dissimilar metals, ensuring long-term reliability. Notably, 5183 welding wire is often specified for joining 5086 aluminum due to its excellent compatibility, providing welds with strength and corrosion resistance comparable to the base material.

Advantages of 5086 Marine Grade Aluminum Products

1. Outstanding corrosion resistance: Exceptional resistance to pitting and stress corrosion cracking in marine environments, suitable for long-term exposure to moisture and saltwater.

2. High strength-to-weight ratio: Lower density than traditional steel with medium strength, enabling lightweight vessel designs that improve fuel efficiency and cargo capacity.

3. Excellent weldability: Compatible with standard welding methods, with minimal loss of joint strength after welding-ideal for manufacturing and repairs.

4. Good formability: Easy to bend and shape, suitable for complex component manufacturing.

5. Superior low-temperature performance: Maintains mechanical properties at extremely low temperatures without brittle fracture.
