What is a 5083 Aluminum Flat Bar?

5083 marine aluminum belongs to the Al-Mg series and mainly contains magnesium (about 4.0-4.9%) with small amounts of manganese and chromium, providing both high strength and excellent corrosion resistance.

The 5083 marine-grade aluminum flat bar is made from 5083 aluminum alloy and processed by rolling or extrusion into flat bar shapes. It is designed specifically for marine environments and highly corrosive applications, commonly used for structural reinforcement, welding and splicing, frame supports, and other applications.

Common Tempers

5083 marine-grade aluminum flat bars are supplied in various tempers to meet different usage environments and processing requirements:

• O Temper: Fully annealed, high plasticity, suitable for components requiring complex forming.

• H111 Temper: Lightly work-hardened, balancing strength and good machinability.

• H112 Temper: Suitable for rolled materials, maintaining original properties while offering good workability.

• H116 Temper: Specially treated for excellent corrosion resistance, ideal for marine environments.

• H321 Temper: Stabilized temper, ensuring long-term durability in marine conditions; commonly used in warships, offshore platforms, and other high-demand applications.

Product Specifications

Features of 5083 Aluminum Flat Bars

1. Exceptional Corrosion Resistance: 5083 aluminum flat bars resist seawater, salt spray, and industrial chemicals, effectively preventing corrosion, extending service life, and reducing maintenance needs.

2. High Strength-to-Weight Ratio: 5083 alloy provides excellent strength while being lightweight, reducing overall vessel weight, improving fuel efficiency, increasing payload capacity, and enhancing sailing speed.

3. Excellent Weldability: 5083 aluminum can be welded using various methods, maintaining strong and reliable weld joints, making fabrication and repair more efficient.

4. Good Formability: Despite its high strength, 5083 flat bars are highly plastic, easy to cut, shape, and machine, allowing manufacturers to customize according to design requirements.

5. Low-Temperature Performance: 5083 alloy maintains mechanical properties at very low temperatures without becoming brittle, making it suitable for cryogenic tanks and low-temperature equipment.

Applications

Thanks to these properties, 5083 flat aluminums are widely used in:

• Keel and frame structures of large ships

• Yacht decks, ladders, and interior components

• Hull structures of marine sightseeing vessels and high-speed ferries

• Support and protective components for offshore oil and gas platforms

Factors Affecting 5083 Aluminum Flat Bar Prices

1. Aluminum Ingot Market Price: Fluctuations in raw material costs are the primary factor.

2. Specifications and Temper: Different thicknesses, widths, and tempers (e.g., H116 requires more processing than O temper) affect prices.

3. Purchase Quantity: Bulk orders usually enjoy lower unit prices.

4. Certification Requirements: Products certified by classification societies incur additional inspection and management costs, resulting in higher prices.

5. Supplier: Pricing strategies vary among suppliers.
