As a seasoned producer of marine aluminum, GNEE manufactures and distributes a range of marine aluminum profiles, such as flat aluminum, T-type aluminum, I-type aluminum, aluminum plate, round tubes, rods, etc. All products are certified by CCS, DNV, and other classification societies, guaranteeing safety in maritime operations, and their dimensions can be altered.
What is a 5083 aluminum flat bar?
5083 marine aluminum is a member of the Al-Mg series and has a high strength and good corrosion resistance due to its high magnesium content (4.0–4.9%) and trace amounts of manganese and chromium.
Made from 5083 aluminum alloy, the 5083 marine-grade aluminum flat bar is formed into flat bar shapes by rolling or extrusion. It is frequently used for welding and splicing, frame supports, structural reinforcement, and other applications. It is especially made for marine environments and extremely corrosive applications
Common 5083 aluminum bar Tempers
To accommodate diverse processing needs and usage conditions, 5083 marine-grade aluminum flat bars are offered in a range of tempers:
O Temper: High plasticity, fully annealed, appropriate for parts that need intricate forming.
H111 Temper: Mildly work-hardened, with good machinability and strength.
H112 Temper: Good workability and preservation of original properties make it appropriate for rolled materials.
H116 Temper: Perfect for marine environments, this temperature has been specially treated for exceptional corrosion resistance.
Warships, offshore platforms, and other high-demand applications frequently use H321 Temper, a stabilized temper that ensures long-term durability in marine conditions.

Features of 5083 Aluminum Flat Bars
1. Outstanding Resistance to Corrosion: 5083 aluminum flat bars are resistant to industrial chemicals, salt spray, and seawater, which stops corrosion, prolongs service life, and lowers maintenance requirements.
2. High Strength-to-Weight Ratio: The 5083 alloy reduces overall vessel weight, improves fuel efficiency, increases payload capacity, and speeds up sailing by offering exceptional strength and low weight.
3. Excellent Weldability: There are several ways to weld 5083 aluminum, resulting in strong and dependable weld joints that increase the efficiency of fabrication and repair.
4. Good Formability: 5083 flat bars are very plastic, easy to cut, shape, and machine, and can be customized by manufacturers to meet design specifications despite their high strength.
5. Low-Temperature Performance: 5083 alloy is appropriate for cryogenic tanks and low-temperature equipment because it retains its mechanical qualities at extremely low temperatures without breaking.
Applications of 5083 Aluminum Bars
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: The main factor is changes in the price of raw materials.
2. Specifications and Temper: Prices are impacted by variations in thicknesses, widths, and tempers (for example, H116 requires more processing than O temper).
3. Purchase Quantity: Unit prices are typically lower for larger orders.
4. Certification Requirements: Classification society-certified products cost more to inspect and manage, which drives up their cost.
5. Supplier: Different suppliers have different pricing policies.
