Application
5383 alloy may be used wherever a stronger welded aluminum structure is desired, from hulls to superstructures. Marine structures benefit from the excellent corrosion resistance offered by 5383. Smaller boats (< 50m) benefit from improved scantlings, which translate into structural weight savings on patrol craft, increased strength on work boats and added interior space in luxury yachts. Larger vessels (> 50m) profit from the increased strength and improved fatigue behavior of 5383 alloy. Cruise ship superstructures can be lightened further while improving stability and not compromising strength or corrosion resistance.
Advantages
15 % higher welded strength than standard 5083 alloy:
- Increased margin of safety from same scantlings.
- Significant weight savings from reduced or modified scantlings.
- Proven improved corrosion resistance.
- Increased fatigue strength.
- Same usage properties as 5083 alloy:
- Formability: Same cutting, bending and shaping.
- Welding: No change in welding procedure, consumables or heat deformation.

Corrosion Resistance
Production H116 and H321 tempers are ASSET tested as per ASTM G66 / ASTM B209, and therefore capable of exhibiting no evidence of exfoliation corrosion. Intergranular corrosion (IGC) and stress corrosion (SCC) tests (Interacid test and ASTM G44) as well as ASSET tests on base and welded metal samples of 5383 show significantly better corrosion resistance than standard 5083. Accelerated (artificial ageing for 7 days at 100°C), natural exposure (marine atmosphere and immersion) and experience have proven the long term corrosion resistance of 5383 to be markedly improved over that of 5083.
