5086 aluminum rod is a key product in the 5000 series aluminum alloy family. Compared with 5052 and 5083 alloys, it has higher strength and stands out for its exceptional resistance to saltwater corrosion, making it ideal for structural components that require long-term exposure to seawater, such as hull frameworks, deck supports, ladders, bulkheads, and other marine structural parts.
As a non-heat-treatable alloy, 5086 aluminum is easy to form, stamp, and weld (TIG welding, MIG welding, and arc welding, etc.). Its main alloying elements are magnesium and silicon, giving it high corrosion resistance, excellent weldability, and medium strength. This makes 5086 marine aluminum rod not only an important material in traditional shipbuilding but also widely used in modern lightweight engineering, marine facility construction, and high-end manufacturing industries.
MC Aluminum supplies a wide range of 5086 aluminum round rods in various specifications. Whether you require different thicknesses, diameters, or hardness levels, we can customize them according to your specific requirements. Our products are certified by DNV GL, BV, LR, ABS, CCS, SGS, and other major classification societies.

Features of 5086 Marine Grade Aluminum Round Rod
Excellent Corrosion Resistance: Stable performance in seawater, industrial atmospheres, and most chemical media; not easily oxidized or corroded.
High Strength & Lightweight: Much lighter than steel while meeting the strength requirements of most load-bearing structures.
Outstanding Weldability: Suitable for TIG, MIG, and arc welding with minimal loss of strength after welding.
Good Formability: Easy to bend, stamp, draw, and machine, making it ideal for manufacturing a variety of structural components.
Stable Low-Temperature Performance: Maintains good toughness and strength even under low-temperature conditions.
Typical Application Fields
Shipbuilding: Hull frameworks, deck supports, ladders, bulkheads, guardrails, and other components in constant contact with seawater.
Marine Engineering: Floating bridges, port facilities, offshore platforms, and offshore wind power foundations.
Compared to other aluminum alloys, 5086 marine aluminum rod offers a balanced combination of high strength, corrosion resistance, weldability, and machinability, making it the ideal choice for marine and high-corrosion environment projects. Its lightweight nature not only reduces structural weight but also improves fuel efficiency and extends service life.
