Applications of 5083 Aluminum Coils
- Ship hulls, decks and superstructure panels
- Tank trailers, road tankers and LNG/CNG cylinders
- Offshore platform wall and floor panels
- Pressure vessels and cryogenic equipment
- Desalination plant cladding and ducts
- Automotive and railway body panels exposed to salt
Slitting, Surface Finish & Fabrication Guidance
| Process | Capability |
|---|---|
| Slitting | Widths from 30 mm; burr-free edges; ±0.2 mm width tolerance |
| Tension leveling | Improves flatness for laser/punch press feeding |
| Anodizing prep | Mill finish suitable for Type II / Type III anodizing |
| Welding | ER5356 / ER5556 filler; argon shielding; no post-weld heat treatment |
| Bending | O temper recommended; H321 offers best strength-formability balance |
| Protective film | PVC/PE film available up to 80 µm to prevent scratches |
See our aluminum welding guide for filler-wire selection and parameter tables.
Packaging, Inspection & Delivery
5083 coils are eye-to-wall or eye-to-sky loaded, wrapped with VCI film, waterproof paper and steel/wooden outer protection, then secured in open-top containers for ocean freight. Each shipment includes mill test certificate (MTC), chemical and mechanical reports, and EN 10204 3.1 on request. Third-party inspection (SGS, BV, TÜV) can be arranged.

Frequently Asked Questions
What is 5083 aluminum coil used for?
5083 aluminum coil is used for marine panels, ship hulls and decks, tank trailers, LNG cylinders, offshore platform walls, pressure vessels, desalination equipment and any saltwater-exposed fabrication that needs high strength and corrosion resistance.
What thickness and width ranges do you offer?
We supply 5083 aluminum coil in thickness 0.2 mm to 12.0 mm and width 1000 mm to 2500 mm. We also provide narrow slit coils down to 30 mm width and cut-to-length sheets on request.
Is 5083 coil suitable for marine use?
Yes. 5083 is a marine-grade alloy. Tempers H116 and H321 are specifically developed for saltwater service because they resist intergranular corrosion and stress corrosion cracking.
What tempers are available for 5083 aluminum coils?
Common tempers are O, H111, H112, H116 and H321. O temper is best for deep drawing and forming, while H116/H321 are preferred for structural marine panels.
What is the MOQ for 5083 aluminum coils?
MOQ is 500 kg per thickness/temper. Mixed loads and trial coils are negotiable.
How long is the lead time?
Stock slit coils ship in 3 – 5 days; production and custom slitting typically take 7 – 25 days depending on quantity and specifications.
Can 5083 coil be welded?
Yes. 5083 has excellent weldability. Use ER5356 or ER5556 filler wire with argon shielding gas. Post-weld heat treatment is not required.
Can you slit 5083 coils to custom width?
Yes. We offer precision slitting from 30 mm up to 2500 mm width, with burr-free edges and tight width tolerance for stamping, laser cutting and automated welding lines.
How does 5083 coil compare to 5086 coil?
5083 offers higher as-welded strength and is the first choice for heavy marine panels and tankers. 5086 is slightly more formable and is often used for lighter welded structures.
How does 5083 coil compare to 5052 coil?
5083 is stronger and more corrosion-resistant in saltwater, making it better for marine and offshore applications. 5052 is easier to form and is ideal for general packaging, fluid lines and decorative parts.
What certificates do you provide?
We provide Mill Test Certificate (MTC), chemical composition report, mechanical test report and EN 10204 3.1 certificate on request.
