What is 5086 Aluminium Alloy?
The alloy behind our square bars, Aluminium 5086, belongs to the widely respected 5000-series — an aluminium-magnesium alloy that achieves strength primarily through cold working (strain hardening), not heat treatment.Â
Key aspects of 5086 Aluminium that make it stand out:
- Magnesium-rich composition — typical magnesium content is 3.5 %–4.5 %. Other alloying elements include manganese (0.2–0.7 %), chromium (0.05–0.25 %), with small amounts of silicon (≤ 0.4 %), iron (≤ 0.5 %), copper (≤ 0.1 %), zinc, titanium, and trace impurities; balance aluminum.Â
- Not heat-treatable — strain hardened instead. This means 5086 retains favorable mechanical properties and weldability after fabrication, without needing post-process heat treatment.
- Good density and lightweight nature — at about 2.66 g/cm³, 5086 offers a strong strength-to-weight ratio, making it a substitute for heavier metals where weight matters.
Why Choose 5086 Aluminium Square Bars
Corrosion Resistance — Especially for Marine & Coastal Use
One of the most significant benefits of 5086 alloy is its excellent resistance to corrosion, especially in saltwater and marine environments. That’s why 5086 is often chosen for boat hulls, ship structures, offshore platforms, and coastal installations.Â
The magnesium-rich composition promotes formation of a stable, protective oxide film, reducing pitting and crevice corrosion even under prolonged exposure to seawater or humid, aggressive atmospheres.
Structural Performance — Strength with Lightness
Because of its alloying and cold-working capabilities, 5086 Aluminium Square Bars deliver medium-to-high strength while remaining significantly lighter than steel or other heavy metals. This makes them ideal for structural frameworks, load-bearing components, platforms, supports, and more — without unnecessary weight penalty.
Fabrication & Welding Flexibility
Since 5086 is not reliant on precipitation hardening, it remains highly weldable and machinable, which is a major benefit for custom fabrication, joins, and assembly. Welded joints retain good strength, minimizing the need for special post-weld heat treatment.Â
Furthermore, in soft temper (O), the alloy remains ductile and easy to form. This combination of formability and eventual strength (after strain hardening) offers flexibility in manufacturing and design.
Typical Applications of 5086 Aluminium Square Bars
Because of its balanced set of properties, 5086 Aluminium Square Bars are used across a wide range of industries and applications. Typical use-cases include:
- Marine & Shipbuilding — hulls, decks, gangways, offshore platforms, coastal structures, yacht fabrication.
- Automotive / Transportation — chassis components, vehicle bodies, fuel-tank supports, trailer bodies — especially where weight reduction helps performance or fuel economy.
- Cryogenic Vessels / Pressure Tanks / Storage Units — benefits from toughness at low temperatures and resistance to corrosive or chemical environments.
- Fabricated Structures / Welded Assemblies — because 5086 welds well and retains strength, it suits welded structures, custom builds, frames, enclosures.
What Sets Our 5086 Aluminium Square Bars Apart — Manufacturer, Supplier & Stockist Excellence
As a committed 5086 Aluminium Square Bars Manufacturer and Supplier / Stockist, we ensure:
- Strict material specifications: chemical composition within defined ranges (Mg, Mn, Cr, Si, etc.), ensuring consistency and alloy integrity.
- Quality control & testing: mechanical properties (yield strength, tensile strength, elongation, hardness) verified as per industry norms, delivering structural reliability.
- Range of tempers & specifications: From soft (O) to cold-worked (H-tempers, e.g. H116, H32 etc.), depending on customer needs (fabrication, welding, strength, forming).
- Cut-to-size and custom sizes: We offer custom square bar sizes, cut-to-length services, and supply ready-to-use bars for easier integration in your manufacturing or construction process.
- Timely supply & stock availability: As stockists, products are ready for dispatch, reducing lead time for procurement.
- Support for fabricators & welders: Because 5086 is weldable and machinable, we also help with advisories on welding, forming, and finishing for best performance.
Choosing 5086 Aluminium Square Bars — What You Should Know
While 5086 offers many advantages, good design and fabrication practices help you get the most out of it:
- Tempering matters: Use annealed (O) temper when good formability or bending is required, then cold-work (if permissible) for higher strength, or order in H-temper for ready-to-use structural strength.
- Account for application environment: 5086 excels in marine, salty, humid, or corrosive conditions — but like any material, ensure proper finishing and maintenance where exposure is severe.
- Match alloy and temper to design requirements: Structural load, fatigue, corrosion exposure, welding, and fabrication methods should influence your choice of temper, finishing treatment, and form factor.
