5083 5086 Marine Grade Aluminum Plate

Deskripsi

Key Properties & Differences of 5083 5086 plat aluminium

Why Choose 5083/5086 aluminum plate for Marine Use?

1. Superior Corrosion Resistance
   • The high magnesium content forms a protective oxide layer, making them highly resistant to saltwater, chlorides, and atmospheric exposure.
   • Commonly used in hulls, decks, and components submerged in seawater.
2. High Strength-to-Weight Ratio
   • Lighter than steel but robust enough to handle dynamic loads in ship structures.
   • Reduces overall vessel weight, improving fuel efficiency.
3. Weldability
   • Both alloys can be welded using TIG, MIG, or laser welding without significant embrittlement.
   • 5083 plat aluminium is preferred for critical welds due to its lower susceptibility to cracking.
4. Marine-Grade Finishes
   • Often supplied in H116 atau H321 tempers, which enhance corrosion resistance and toughness.
   • Can be further treated with anodic oxidation or epoxy coatings for added protection.

Applications in Shipbuilding

• Hull Construction: Used for plating, bulkheads, and frames.
• Deck Structures: Lantai, walkways, and hatches.
• Superstructures: Aluminum masts, cabins, and ventilation systems.
• Tanks & Piping: Tangki bahan bakar, water tanks, and seawater pipelines.
• Offshore Platforms: Modules, gangways, and corrosion-resistant panels.

Key Standards

• ASTM B209 (5083/5086 sheet/plate)
• EN 573-3 (aluminum alloy products for marine applications)
• ABS/DNV GL certifications for shipbuilding compliance

Choosing Between 5083 dan 5086

• 5083 is ideal for high-stress components requiring maximum strength (e.g., hull plating, heavy-duty brackets).
• 5086 offers better formability and is often used for complex shapes or cost-sensitive projects (e.g., perlengkapan interior, smaller vessels).
