What Is 5083 H111 Aluminum?
5083 H111 aluminum is a high-strength, non-heat-treatable aluminum-magnesium alloy featuring light work hardening, exceptional corrosion resistance, and excellent weldability. It is widely recognized as a marine-grade aluminum alloy for demanding environments.
Alloy 5083 H111 is an Al-Mg-Mn alloy with light work hardening introduced during shaping, leveling, flattening, or production processes. The H111 temper has less strain hardening than H11 temper, providing a practical balance between strength, formability, and welding performance.
Compared with fully annealed O temper material, 5083 H111 generally provides higher strength while retaining good ductility, bending performance, forming capability and weldability. It is commonly used where a practical balance of corrosion resistance, moderate strength and fabrication flexibility is required.
At Haomei Aluminum, our 5083 H111 aluminum plate and sheet are produced with controlled chemical composition, stable rolling processes, surface inspection, flatness control, and mechanical-property testing. Material Test Certificates (MTCs) can be provided for each production batch according to the agreed order requirements.
For projects requiring enhanced corrosion-resistance performance in marine environments, please also review our 5083 H116 aluminum plate and 5083 H321 marine aluminum plate.

5083 H111 Aluminum Plate Corrosion Resistance
5083 is a high-magnesium Al-Mg corrosion-resistant alloy commonly used in marine-grade aluminum applications. It is suitable for many seawater, marine-atmosphere and high-humidity environments when correctly selected, fabricated and maintained.
The high magnesium content of 5083 aluminum supports strong resistance to corrosion in marine and industrial environments. It is often used for shipbuilding, ferry structures, deck components, offshore-related equipment, tank fabrication and welded structural applications where weight reduction and corrosion resistance are both important.
Corrosion performance depends not only on alloy and temper but also on material thickness, surface condition, fabrication method, welding procedure, design details, drainage conditions, galvanic isolation, coating system and service environment.
Seawater Exposure
Suitable for many marine applications where saltwater exposure and humid marine atmosphere resistance are required.
Salt Spray Environment
Useful in high-humidity and salt-spray service conditions when material, design and corrosion protection are properly selected.
Industrial Environment
Offers useful corrosion resistance in many industrial environments, subject to chemical concentration, temperature and exposure conditions.
Marine Temper Selection: H116 and H321 are commonly specified for applicable marine and offshore products requiring controlled corrosion-performance characteristics. The choice between H111, H116 and H321 must follow project specifications, applicable standards and required inspection documentation.

5083 H111 Aluminum Temper: Properties, Applications and Comparison
H111 is a lightly strain-hardened temper used for non-heat-treatable aluminum alloys. It provides a balance between mechanical strength, formability and fabrication flexibility.
The H111 temper generally indicates that the aluminum product has undergone a degree of strain hardening but less than the amount required for a controlled H11 temper. It is frequently used in applications where bending, fabrication, welding and general structural performance are all important.
Compared with O Temper
H111 generally provides higher strength than fully annealed O temper while retaining good ductility and fabrication capability.
Compared with H116
H111 is often selected for good formability and general welded structures. H116 may be specified for applicable marine products requiring controlled corrosion-performance characteristics.
Compared with H321
H321 is a stabilized temper commonly used in applicable Al-Mg marine and structural products. Final selection depends on specification, thickness, corrosion exposure and project requirements.
5083 Temper Comparison
| Temper | General Strength Level | Formability | Typical Use | Selection Note |
| O | Lower | Best | Deep-drawn parts, highly formed components | Fully annealed condition; suitable where maximum forming is required. |
| H111 | Moderate | Good | General welded structures, formed panels, tank fabrication | Useful balance of strength, weldability and fabrication flexibility. |
| H112 | Moderate | Good | Thicker plate, hot-worked products and structural components | Commercially supplied temper; confirm mechanical requirements by standard. |
| H116 | Moderate to Higher | Medium | Applicable marine and offshore products | Often specified where controlled corrosion-performance requirements apply. |
| H321 | Moderate to Higher | Medium | Marine, structural, tank and selected transport applications | Stabilized temper; final applicability depends on product standard and project requirement. |
