Marine‑grade strength and corrosion resistance for safer, lighter vessels

From high‑strength AA5059 (ALUSTAR®) to proven 5083 H128, Novelis delivers marine aluminum plates engineered for demanding hull plating, deck and ship superstructure applications, combining durability with design efficiency.

Application Overview

Hull plating, decks, ship superstructures

Components welded with AA5183 filler wire in accordance with industry practice and classification tests

Key Benefits

High strength with safety margin:
ALUSTAR® (AA5059) offers higher yield strength compared with common AA5083 grades, supporting robust designs.

Marine‑grade corrosion resistance:
Proven performance in marine environments and compatibility with industry welding practices.

Efficiency in build and design:
Wide thickness/current windows for pulsed MIG welding support consistent fusion and productivity across plate gauges.

Technical Specs

Representative properties (typical values):

AA5059 H111 (12.5–40 mm):
