Product Description
5083 H116 Marine Grade Aluminum Alloy Plate 3mm-200mm Thickness for Shipbuilding Hull Structure Applications
5083 H116 Marine Grade Aluminum Alloy Plate for Shipbuilding and Offshore Structures
The 5083 H116 aluminum alloy plate is the premier material for marine and offshore applications, engineered to deliver maximum corrosion resistance in aggressive seawater environments. With the highest strength among non-heat-treatable alloys and superior weldability, it is the material of choice for ship hulls, superyacht structures, offshore platforms and cryogenic storage tanks. The H116 temper is specifically designed to resist exfoliation and intergranular corrosion in marine service.
Key Features
- Premium Marine Alloy: 4.0-4.9% magnesium content delivers the highest strength and best corrosion resistance in the 5000 series
- H116 Special Temper: Specifically processed to provide immunity to exfoliation corrosion and intergranular attack in saltwater service
- Classification Society Approved: Certified by DNV, ABS, BV and LR to meet shipbuilding and offshore structure requirements
- Exceptional Weldability: Excellent TIG and MIG welding characteristics with 5356 filler maintaining joint strength and corrosion resistance
- Cryogenic Performance: Retains toughness and ductility at temperatures as low as -196°C for LNG containment systems
- Stress Corrosion Cracking Resistant: Specifically processed grain structure eliminates sensitization to SCC in marine environments
