MC Aluminum produces 2x6m 5083 marine-grade aluminum plates specifically for shipbuilding and offshore engineering applications where high strength, excellent corrosion resistance, and superior weldability are required. Thanks to its outstanding seawater corrosion resistance, this aluminum plate is ideal for use in lightweight boats, speedboats, deck structures, bulkheads, edge sealing, and reinforcement strips.

Overview of 5083 Aluminum Plate

5083 aluminum alloy belongs to the Al-Mg-Mn series, known for its excellent resistance to seawater corrosion, high strength, and good weldability, making it an indispensable material in the marine industry. Especially in structural parts like hulls, bulkheads, decks, and base plates, 5083 aluminum can replace traditional steel, offering weight reduction and enhanced durability.

Compared to other common aluminum alloys such as 5052 and 5086, 5083 excels in tensile strength, yield strength, and corrosion resistance, making it particularly suitable for long-term service in high-humidity, high-salt environments.

Significance of the 2m x 6m Size

The 2m x 6m format is a standard plate size among major aluminum manufacturers and is especially suitable for marine and industrial applications.

This dimension meets building standards while ensuring easier handling and transportation without compromising structural integrity. Pre-cut sizing also reduces offcuts and material waste during fabrication, helping lower material costs and processing time—an important advantage in shipbuilding and similar projects.

Multifunctionality: Leading the Way in Marine Structures

With its excellent comprehensive performance, 5083 aluminum plate demonstrates strong adaptability in marine environments. Its magnesium content (approximately 4.0%-4.9%) ensures high tensile strength (270-345 MPa) and exceptional corrosion resistance-with corrosion rates as low as 0.001mm/a in chloride-rich environments-effectively resisting seawater and chemical damage.

Its outstanding weldability allows joint efficiency up to 95%, with post-weld strength retention over 90%, meeting the high-stress demands of ship structures. Moreover, it supports various cold-working processes such as bending and stamping, offering great design flexibility for shipbuilding and repairs.

Green & Sustainable: 100% Recyclable for Eco-Friendly Projects

In terms of sustainability, 5083 aluminum plates are fully recyclable, reducing carbon emissions significantly. A closed-loop recycling system can cut material reuse costs by 40%, supporting green transformation across industries.

Its lightweight properties (density ~2850 kg/m³) reduce vessel weight by up to 18% and improve fuel efficiency by 12%, optimizing the environmental performance over a ship’s lifecycle. Additionally, the material is certified by CCS, ABS, and other international classification societies, ensuring long-term reliability and becoming the go-to choice for maritime applications.

Process Control: From Ingot to Precision Plate

Producing large-format 2x6m 5083 marine aluminum plates involves overcoming multiple technical challenges, particularly in flatness control, grain refinement, uniformity, and mechanical performance retention. MC Aluminum employs the following key processes to ensure consistent quality:

• Hot rolling with online homogenization: Ensures dense microstructure and uniform strength.

• Stretch leveling process: Improves plate flatness and reduces warping and residual stress.

• Multi-stage quality inspections: From chemical composition control during smelting to final tensile testing, all meet CCS, DNV, ABS classification standards.
