Welcome to Hemaokang Steel (Shandong) Co., Ltd. As a trusted supplier in the global metal industry, we are proud to present our 5083-H116 Aluminum Plate – a premium shipbuilding-grade material designed for demanding marine environments. With a thickness of 12mm and dimensions of 1500mm x 3000mm, this plate offers excellent corrosion resistance, high strength, and reliable performance. Our commitment to quality is backed by ISO9001 certification and an annual export value of US$50 million to US$100 million, serving markets across North America, Europe, Asia, Africa, and Oceania.
The 5083-H116 aluminum alloy is specifically formulated for marine applications, providing exceptional resistance to seawater corrosion and stress corrosion cracking. The 12mm thickness combined with a 3.2mm tolerance ensures precise dimensional control, meeting the rigorous standards of shipbuilding and offshore structures. Whether you need material for hulls, decks, or superstructures, this plate delivers the durability and workability required for long-term service.
Key Features & Technical Specifications
- Superior Corrosion Resistance: The 5083 alloy offers excellent resistance to seawater, industrial chemicals, and atmospheric corrosion, making it ideal for marine environments.
- High Strength & Weldability: With a minimum tensile strength of 275 MPa, this plate provides structural integrity while being easily weldable using standard methods.
- Precise Dimensional Control: The 3.2mm tolerance (typically ±1.6mm for thickness) ensures consistent performance and easy integration into fabrication processes.
- Shipbuilding Grade Approval: Compliant with major classification societies (e.g., DNV, ABS, Lloyd's) – available upon request, ensuring suitability for marine applications.
- Large Sheet Size: 1500mm x 3000mm reduces the number of joints required, saving time and labor costs during fabrication.
- Excellent Formability: The H116 temper provides good ductility for bending, forming, and machining operations.
- Non-Magnetic & Lightweight: Aluminum is non-magnetic and approximately 1/3 the weight of steel, reducing overall vessel weight and improving fuel efficiency.
- Recyclable & Eco-Friendly: 100% recyclable material supports sustainable manufacturing practices.

Why Choose Our 5083-H116 Aluminum Plate?
Our aluminum plate is manufactured using advanced rolling and heat treatment processes to ensure consistent mechanical properties and dimensional accuracy. The 3.2mm tolerance is particularly important for shipbuilding applications where tight fits and precise alignment are critical. This plate is suitable for:
- Ship Hulls & Decks: Resists seawater corrosion and reduces overall weight.
- Offshore Platforms: Withstands harsh marine environments and cyclic loading.
- Marine Vessels: Ideal for superstructures, bulkheads, and internal fittings.
- Chemical Storage Tanks: Excellent resistance to corrosive chemicals.
- Transportation Equipment: Lightweight and durable for trailers, containers, and railcars.
Compared to other aluminum alloys, 5083 offers superior performance in welded structures, maintaining strength in the heat-affected zone. The H116 temper is specifically designed for marine use, providing enhanced resistance to exfoliation corrosion and stress corrosion cracking.

Frequently Asked Questions (FAQ)
-
What is the difference between 5083-H116 and 5083-H321?
H116 is a marine-specific temper that offers improved resistance to exfoliation corrosion, while H321 is a strain-hardened temper with slightly higher strength. For shipbuilding, H116 is typically preferred. -
Does this plate come with a mill certificate?
Yes, we provide a mill test certificate (MTC) with each shipment, verifying chemical composition and mechanical properties. -
Can you cut the plate to custom sizes?
Absolutely. We offer custom cutting services (plasma, laser, or saw) to meet your specific dimensions. Contact us for details. -
What is the packaging for export?
Plates are packed with waterproof paper, wooden crates, or steel pallets to prevent damage during transit. We follow international export standards. -
Is this product suitable for welding?
Yes, 5083 alloy has excellent weldability using MIG or TIG methods with appropriate filler metals (e.g., ER5356). No post-weld heat treatment is required. -
What is the lead time for an order?
Standard lead time is 7-15 working days after order confirmation, depending on quantity and customization. Express shipping is available upon request. -
Do you offer samples for testing?
Yes, we can provide small samples (e.g., 200mm x 200mm) at a nominal cost, with shipping charges applicable. Please contact our sales team. -
What payment terms do you accept?
We accept T/T (telegraphic transfer), L/C (letter of credit), and other negotiable terms for large orders. Minimum order quantity may apply.
