Introduction

5083 Aluminum Plate (also 5083 Aluminum Sheet, Marine Grade Aluminum Plate, 5083-H116 Aluminum Plate, 5083-H321 Aluminum Sheet, Aluminum Alloy 5083 Plate, Shipbuilding Aluminum Plate, Aluminum Marine Sheet, High Magnesium Aluminum Plate, or Offshore Aluminum Plate) is a non‑heat‑treatable aluminum‑magnesium alloy with excellent seawater corrosion resistance. It conforms to ASTM B209, EN AW-5083, and AA5083, available in tempers 5083-H116 (for plate) and 5083-H321 (for sheet/plate, strain hardened and stabilized), as well as H111, H112, and O temper.

This marine grade aluminum 5083 offers excellent seawater corrosion resistance, marine grade aluminum alloy, high strength aluminum plate, lightweight shipbuilding aluminum, weldable marine aluminum sheet, cryogenic resistant aluminum alloy, durable offshore aluminum plate, chloride resistant aluminum alloy, high performance marine aluminum, and anti corrosion aluminum plate. It maintains high strength even at cryogenic temperatures, making it ideal for LNG storage.

Note: 5083 is not recommended for prolonged exposure to elevated temperatures (>65°C) due to sensitization risk.

Our 5083-H116 / H321 plates and sheets are supplied in mill finish, polished, checker plate (tread plate), and cut‑to‑size forms. We offer custom sizes, large size, and CNC machining services.

Key standards: ASTM B209, EN AW-5083, AA5083, UNS A95083.

Applications

1. Shipbuilding & Boat Building

• 5083 aluminum plate for shipbuilding – hull plating, superstructures, bulkheads, decks, and stiffeners for cargo ships, ferries, patrol boats, and yachts. Marine grade aluminum plate reduces vessel weight, improving speed and fuel efficiency.

• 5083 aluminum sheet for boat building – small boat hulls, pontoon boats, landing craft, and workboat decks. Excellent seawater corrosion resistance ensures long service life without painting.

• 5083 aluminum for marine applications – ship ladders, gangways, handrails, and marine hardware. Lightweight shipbuilding aluminum is easy to weld and fabricate.

2. Offshore Platforms & Marine Structures

• 5083 aluminum plate for offshore platforms – helideck surfaces, living quarters, walkways, and splash zone cladding. Durable offshore aluminum plate withstands salt spray, wave impact, and UV exposure.

• Offshore aluminum sheet supplier – provides 5083 sheet for platform railings, cable trays, and firewater system components. Chloride resistant aluminum alloy prevents pitting and crevice corrosion.

3. LNG Tanks & Cryogenic Applications

• 5083 aluminum sheet for LNG tanks – inner and outer shells of LNG storage tanks, transport vessel tanks, and cryogenic trailers. High strength marine aluminum alloy retains excellent toughness at cryogenic temperatures (down to -196°C).

• 5083 aluminum plate for cryogenic applications – liquid nitrogen, liquid oxygen, and liquid hydrogen storage vessels. Weldable marine aluminum sheet with superior low‑temperature impact resistance.

4. Pressure Vessels & Fuel Tanks

• 5083 aluminum plate for pressure vessels – low‑temperature pressure vessels, air receivers, and process tanks in marine and industrial service. High strength aluminum plate meets ASME codes.

• 5083 aluminum sheet for fuel tanks – marine fuel tanks, diesel storage tanks, and hydraulic fluid reservoirs. Anti corrosion aluminum plate prevents contamination and leakage.

5. Transportation & Industrial Equipment

• 5083 aluminum sheet for transportation industry – truck and trailer flooring, container panels, bulk cargo trailers, and railway hopper cars. Lightweight marine aluminum plate increases payload.

• 5083 aluminum plate for industrial equipment – chemical tanker bodies, process vessels, and high‑corrosion environments where 6061 may be insufficient. High performance marine aluminum with excellent weldability.
