Engineered with a strong magnesium chemistry (Al-Mg 4.5-Mn), 5086 obtains strength by cold work rather than heat treatment, allowing it to be welded without losing mechanical integrity.
Its tensile qualities outperform those of 5052 and 5083, and its better ductility allows for smooth bends and precision forming, making it the preferred alloy for boat hulls, ramps, decks, and yacht superstructures.
5086 marine-grade aluminum sheet, available in gauges ranging from 0.250" to 2.00" and widths up to 120" × 300", combines high strength with superior seawater corrosion resistance.

5086 Aluminum Sheet Application
Marine Hulls and Superstructures: Plate for boat and yacht hulls, decks, bulkheads, and superstructure panels, designed to withstand persistent saltwater exposure while maintaining structural integrity.
Offshore Oil & Gas Platforms: Structural members, walkways, and handrails on drilling rigs and production platforms require high resistance to seawater corrosion and fatigue.
Cryogenic Storage Tanks: Liners and interior components for LNG and other cryogenic liquid containment, utilizing 5086's low-temperature durability.
Shells, end caps, and baffles are used in non-combustible gas and liquid pressure vessels, boilers, and heat exchanger plates.
Heavy-duty and military vehicles require armor plate, chassis frames, and body panels with high strength-to-weight ratios and weldability.
