AA5083 H116 aluminium plates are widely recognized as one of the most reliable marine-grade aluminium alloys used in shipbuilding and offshore engineering applications. Known for their exceptional corrosion resistance, high strength, and excellent weldability, these plates are specifically designed to perform in harsh marine environments where materials must withstand constant exposure to seawater, humidity, and extreme weather conditions.
Shipyards, marine engineering companies, offshore equipment manufacturers, and naval defense industries prefer AA5083 H116 aluminium plates because they combine durability with lightweight performance. Compared with traditional steel materials, aluminium marine plates significantly reduce vessel weight while maintaining structural integrity, improving fuel efficiency and operational performance.
Hindustan Steel Corporation supplies high-quality AA5083 H116 marine grade aluminium plates sourced from globally approved mills. Our supply range supports shipbuilding and offshore engineering projects worldwide, ensuring reliable materials that meet international marine standards.
AA5083 H116 is a high-magnesium aluminium alloy designed for marine and structural applications where corrosion resistance and strength are critical.
The alloy belongs to the 5000-series aluminium family, which is known for excellent resistance to saltwater corrosion and superior mechanical properties.
The designation AA5083 H116 represents:
| Symbol | Meaning |
|---|---|
| AA | Aluminium Alloy |
| 5083 | Magnesium alloyed aluminium |
| H116 | Strain-hardened temper designed for marine applications |
Because of its outstanding performance in seawater environments, AA5083 H116 is commonly used for hull structures, ship decks, marine tanks, and offshore platforms.
The manufacturing process of AA5083 H116 aluminium plates involves precise alloying and controlled rolling techniques to achieve superior strength and corrosion resistance.
Production begins with melting high-purity aluminium combined with magnesium and trace alloying elements. The molten metal is cast into slabs, which are then hot rolled into plates of various thicknesses.
After rolling, the plates undergo strain hardening and controlled heat treatment processes to achieve the H116 temper. This temper ensures improved resistance to exfoliation corrosion and stress corrosion cracking in marine environments.
The final plates undergo strict inspection and quality testing to ensure they meet international marine-grade standards.
