5083 Aluminium Sheet H116 Temper 1.0-50.0mm Shipbuilding Aluminium Plate for Vessel Hull LNG Tank Fabrication
5083 Aluminium Sheet Shipbuilding Grade
5083 aluminium sheet is the strongest non-heat-treatable alloy commonly used in shipbuilding. With magnesium and manganese additions it maintains high strength after welding and performs exceptionally in cryogenic and marine environments.
Key Selling Points
- High strength retaining properties after welding for hull structures
- Proven performance in cryogenic LNG tank applications
- Superior corrosion resistance in seawater with long service life
- Available in H116 and H321 tempers with full mechanical test certification
- Thick plate range 1.0-50.0mm for structural and heavy fabrication
