Naval Aluminium Sheet Marine 5052 H32 is a premium-grade aluminum alloy sheet specifically engineered for marine and naval applications. Known for its excellent corrosion resistance, high strength-to-weight ratio, and superior weldability, this aluminum alloy meets the rigorous demands of harsh maritime environments.

5052 Marine Aluminum Sheet in the H32 temper is carefully processed to achieve moderate hardening through strain hardening and stabilization. It combines medium tensile strength with enhanced formability and corrosion resistance, critical for marine construction.

Features

Exceptional Corrosion ResistanceResists seawater corrosion, pitting, and crevice corrosion, making it ideal for shipbuilding and offshore platforms.
Good WeldabilitySuitable for TIG and MIG welding without compromising mechanical properties.
Moderate StrengthOffers good tensile and yield strength optimized by the H32 strain hardening temper.
Good FormabilityExhibits excellent bending and forming characteristics without cracking.
LightweightWith a density significantly lower than steel, it reduces overall vessel weight improving fuel efficiency and payload capacity.
