High Strength 5000 Series 5083 Aluminum Marine Plate Aluminium 5083 Sheet

5083 aluminum sheet belongs to Al-Mg series alloy. It is the highest strength corrosion-resistant

alloy among practical non-heat-treated alloys. And it is suitable for welding structures. Also, it is

worth mentioning that 5083 aluminum sheet has good resistance to seawater and low-temperature

characteristics.

Our Company

♦ We have implemented standardized processes to enhance work efficiency, reduce confusion,

minimize errors, and boost overall productivity.

♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,

fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth

motivation, while enhancing team cohesion and a sense of belonging.

We use the World-advanced Equipments

These are some samples we made below :

Ocean Shipping

For oversize sheet, we use Flat Rack Container

1) We use suitable securing material, such as wooden blocks, steel straps, and ratchet tie-downs

to firmly fix the aluminum plates to the flat rack.

2) To prevent possible exposure to seawater or rain, we cover the entire cargo with waterproof tarps.

3) We make sure these sheets are loaded with a low and evenly distributed center of gravity to avoid

tilting during the transportation.

Key Properties of 5083 Aluminum Alloy

5083 aluminum alloy is a non-heat-treatable Al-Mg series alloy with exceptional marine-grade

characteristics:

♦ Superior Corrosion Resistance

High Mg content (4.0-4.9%) provides industry-leading seawater corrosion resistance

Resists stress corrosion cracking (SCC) in long-term marine exposure

♦ Outstanding Weldability

Compatible with MIG/TIG/FSW (friction stir welding)

As-welded joint strength retains >90% of base material

No post-weld heat treatment required

♦ Cryogenic Performance

Maintains toughness in Arctic conditions (-196°C) without brittle fracture

Material Selection & Processing Notes

Temper Selection:

H116/H321: Standard for optimized strength/corrosion resistance

O temper: For complex cold-formed shapes

Corrosion Protection:

Combine with sacrificial anodes or epoxy coatings

Comparison with Other Marine Alloys

5052: Lower strength (interior/cost-sensitive uses)

6061: Heat-treatable but inferior seawater resistance
