5086 H111 material is a non-heat-treatable aluminum-magnesium alloy in a lightly strain-hardened condition. It is widely known for its excellent corrosion resistance, particularly in marine and industrial environments, as well as its superior weldability and moderate structural strength.
Compared with other tempers like H32 or H116, the H111 condition offers significantly better formability, making it the ideal choice for applications that require heavy bending, deep drawing, and general fabrication without the risk of material cracking.
Decoding 5086 H111 Aluminum
To fully understand how this material behaves in a workshop, engineers and procurement teams must break down its technical designation:
- 5086 Alloy: This is a 5xxx series marine-grade aluminum alloy. It contains less magnesium than 5083 but more than 5052, providing a perfect middle ground between high strength and excellent workability.
- Non-Heat-Treatable: Like all 5xxx series alloys, 5086 cannot be strengthened by thermal treatment. Its strength is achieved solely through cold working (strain hardening).
- H111 Temper: The "H11" indicates it is slightly strain-hardened. The "1" specifies that it has undergone a very limited amount of work hardening during the final forming processes (like stretching or leveling), but it remains highly ductile.
Summary: 5086 H111 is essentially a "semi-soft" aluminum alloy designed specifically for severe forming and complex welding applications.
Chemical Composition of 5086 Aluminum
The performance of the 5086 alloy is dictated by its carefully balanced chemical makeup.
| Element | Content (%) | Engineering Function |
| Magnesium (Mg) | 3.5 – 4.5 | Provides core strength and outstanding marine corrosion resistance. |
| Manganese (Mn) | 0.2 – 0.7 | Increases tensile strength and improves the internal grain structure. |
| Chromium (Cr) | 0.05 – 0.25 | Acts as an inhibitor against stress corrosion cracking. |
| Silicon + Iron (Si + Fe) | ≤ 0.5 | Kept low to prevent brittleness and ensure excellent weldability. |
| Zinc (Zn) | ≤ 0.25 | Strictly limited to protect the alloy's anti-corrosion properties. |
| Aluminum (Al) | Remainder | The base matrix. |
Mechanical Properties of 5086 H111
When evaluating 5086 H111 for fabrication, its elongation rate is its greatest asset. It allows for tight bending radii that harder tempers simply cannot achieve.
| Property | Typical Value |
| Tensile Strength (Ultimate) | ≈ 260 – 300 MPa (38,000 – 43,500 psi) |
| Yield Strength | ≈ 110 – 140 MPa (16,000 – 20,000 psi) |
| Elongation (in 50mm) | ≥ 12 – 20% (Highly dependent on thickness) |
| Hardness (Brinell) | ≈ 58 HB |
Engineering Note: 5086 H111 provides lower tensile and yield strength than the H32 or H116 tempers, but it offers far superior ductility. This is critical when manufacturing curved panels or cylindrical tanks.

5086 H111 vs Other Tempers (H32 and H116)
Selecting the correct temper is crucial. A common mistake in procurement is buying an H116 plate for a bending application, only to have the metal crack on the press brake. Here is the core comparison:
| Temper | Material Condition | Key Features | Best Use Cases |
| H111 | Lightly strain-hardened | Excellent formability, highly ductile. | Bending, tank forming, general fabrication. |
| H32 | Strain-hardened + quarter hard | Higher strength, decent workability. | Standard structural use, flat vehicle panels. |
| H116 | Strain-hardened (corrosion optimized) | Maximum resistance to saltwater exfoliation. | Heavy shipbuilding, offshore platforms. |
Summary: H111 is optimized for bending and forming, while H116 is optimized strictly for structural marine durability.
Applications of 5086 H111 Aluminum Material
Thanks to its balanced properties, 5086 H111 is extensively utilized in industries where metal needs to be heavily worked before final assembly:
- Vehicle Panels: Used for manufacturing curved dump truck bodies, specialized trailers, and railway carriage panels.
- Storage Tanks: Its high elongation makes it the standard material for rolling cylindrical road tankers and unpressurized chemical storage vessels.
- Marine Structures (Non-Critical): Perfect for interior boat cabins, consoles, and non-load-bearing bulkheads where complex shapes are required.
- Welded Assemblies: 5086 retains excellent joint strength after MIG/TIG welding, making it ideal for complex architectural frameworks.
- General Fabrication: Used widely in machine bases, structural brackets, and heavy-duty enclosures.
When to Choose 5086 H111 Aluminum
Make the right procurement decision by matching the material directly to your project needs:
Choose 5086 H111 if:
- Your production process requires severe CNC bending, rolling, deep drawing, or pressing.
- You require highly reliable weldability with minimal loss of strength in the heat-affected zone (HAZ).
- Moderate structural strength is sufficient for your design load.
- You are building road transport equipment or standard industrial tanks.
Do NOT choose 5086 H111 if:
- You are constructing primary ship hull structures below the waterline.
- The project involves long-term, direct seawater exposure (like offshore oil rigs).
- The end-user strictly demands classification society certification (ABS, DNV, LR) for marine exfoliation resistance (choose 5086 H116 instead).
