5005 aluminum plate is a low-strength, non-heat-treatable alloy in the 5000 series, renowned for its excellent corrosion resistance, formability, and weldability. It is widely used in marine, construction, and industrial applications, where durability and resistance to harsh environments are critical.
5005 aluminum plate is primarily composed of aluminum, with a small but essential amount of magnesium (typically 0.5-1.1%), which provides moderate strength while maintaining excellent corrosion resistance.
5005 aluminum plate strikes a balance between strength, corrosion resistance, and excellent surface finish. Its chemical composition allows it to be cold-worked to improve mechanical properties while maintaining good weldability and excellent anodizing characteristics. This makes it an ideal material for both structural and decorative applications, especially where exposure to corrosive environments is a concern.
The 5005 aluminum alloy is widely used in various fields due to its excellent formability, corrosion resistance, and weldability. It is a high-performance medium-strength aluminum alloy.
Common tempers for 5005 aluminum include O (annealed), H32, H34, and H38. For example, the H34 temper represents a partially cold-worked condition that provides a good combination of strength and ductility.
| Features | Description |
| Excellent Corrosion Resistance | 5005 aluminum plate offers outstanding corrosion resistance, especially in humid environments and marine atmospheres. This is primarily due to the magnesium content, which helps form a stable oxide layer in atmospheric, freshwater, and mild chemical environments, enhancing its corrosion resistance. Compared to some high-strength alloys like the 2xxx and 7xxx series, 5005 aluminum plate can maintain a long service life without additional protective coatings, making it ideal for use in construction, marine, and food processing equipment, where excellent corrosion resistance is essential. |
| Easy to Anodize | 5005 aluminum plate, due to its uniform chemical composition and relatively pure aluminum base, is capable of undergoing high-quality anodizing. After anodizing, the 5005 aluminum plate forms a dense oxide film on the surface, enhancing its corrosion resistance and allowing for decorative coloring through electrolytic coloring. Compared to other aluminum-magnesium alloys like 5052, the anodized film on 5005 aluminum plate is more uniform in color, making it widely used in architectural finishes, electronic enclosures, signage, and other applications that require a high-quality anodized surface. |
| Medium Strength Aluminum Alloy | 5005 aluminum plate falls between the low-strength 1xxx series pure aluminum and the high-strength 5xxx series high-magnesium aluminum alloys (such as 5083, 5754), making it a medium-strength aluminum alloy. |
| Good Formability | 5005 aluminum plate, in the annealed state (O temper), exhibits excellent plasticity, allowing it to be easily processed into complex shapes through cold working methods such as stamping, deep drawing, and bending. In H series tempers (such as H32, H34), while strength is improved, the alloy still retains good formability. Compared to high-strength aluminum alloys, 5005 aluminum plate is less prone to cracking during processing, making it ideal for manufacturing complex parts and applications requiring high formability, such as architectural curtain walls, kitchen equipment, and aircraft pipeline supports. |
| Suitable for Applications Requiring Bending, Spinning, Stretching, Stamping, and Rolling | Due to its excellent plasticity and moderate strength, 5005 aluminum plate is suitable for various forming processes. It does not easily fracture during bending, making it ideal for curved structural components in architectural decoration; it maintains stability during spinning processes, allowing the manufacture of cylindrical containers and tubes; it performs well in stretching and stamping processes, making it suitable for automotive body panels and electronic product enclosures; additionally, during rolling processes, 5005 aluminum plate can be formed into corrugated sheets or other continuous profiles, widely used in building materials and signage industries. |
| Commonly Used in Applications Requiring Anodizing | Since 5005 aluminum plate forms a uniform, aesthetically pleasing, and corrosion-resistant oxide layer after anodizing, it is highly favored in many high-demand applications. For example, building curtain walls, household appliance enclosures, electronic device panels, and traffic signage all require anodizing to enhance both aesthetic appeal and weather resistance. Furthermore, 5005 aluminum plate is also used in the production of high-end interior decorative materials such as ceilings, window frames, and furniture panels to meet both aesthetic and durable usage requirements. |
This aluminum is the weakest of the non-heat-treatable aluminum alloys. However, it can be hardened by cold working, is well suited for decorative anodizing, and has good weldability.
While the 5005 aluminum plate has some advantages, such as good anodizing performance, weldability, and cold working hardening ability, its relatively low strength and the limitation that its strength cannot be improved through heat treatment, make it inadequate in some high-strength applications.
5005 Aluminum Plate Advantages
| Advantages | Description |
| Suitable for Decorative Anodizing | 5005 aluminum plate is particularly suitable for decorative anodizing treatment. Due to its relatively pure aluminum substrate and uniform chemical composition, it forms a uniform and attractive oxide film after anodizing. This oxide film not only provides excellent corrosion resistance but also enhances the surface appearance. The anodized 5005 aluminum plate has a uniform color, making it ideal for applications requiring high-quality aesthetics, such as architectural decoration, electronic product housings, and traffic signs. |
| Good Weldability | 5005 aluminum plate has excellent weldability, especially in conventional TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding processes. Its lower strength and high ductility reduce the likelihood of cracking or distortion during welding, making it suitable for welded structural components and casing assemblies, such as automobile bodies, architectural decoration pieces, and kitchen equipment. Its good weldability also makes 5005 aluminum plate an ideal material for shipbuilding and transportation sectors. |
| Cold Work Hardening | Although 5005 aluminum plate is an alloy that cannot be heat treated, its strength can be enhanced through cold working. During the cold working process, the material’s grain structure changes, increasing its strength and hardness. This makes 5005 aluminum plate very suitable for applications requiring moderate strength, such as traffic signs, furniture, and certain building structural components, while maintaining good machinability and formability. |
5005 Aluminum Plate Disadvantages
| Disadvantages | Description |
| Low Strength | The strength of 5005 aluminum plate is relatively low, especially when compared to some heat-treated aluminum alloys (such as 7075, 7050, etc.), where its tensile and yield strengths are weaker. |
| Cannot be Heat Treated | 5005 aluminum plate is a non-heat-treatable alloy, meaning it cannot be further strengthened through heat treatment processes (such as solution heat treatment or aging). Therefore, its strength can only be improved by cold working, and not by heat treatment. |
| Prone to Surface Scratches | Although 5005 aluminum plate's surface can achieve good corrosion resistance and appearance through anodizing, it is relatively soft and prone to surface damage, such as scratches and wear, during processing or transportation. |

5005 has excellent formability, especially in softer tempers. SAF carriers 5005 H34 temper which is slightly harder and is comparable to 5052 H32 for forming.
5005 alloy is noted for excellent welding characteristics. When 5005 material will be welded and then anodized, SAF recommends a 5356 welding wire for best color uniformity. Weld discoloration can still occur, but it is less severe than other welding alloys.
5005 machinability is generally fairly poor. Soft 5005 tempers machine worse than harder tempers. 5005 H34 and 5005 H38 can be machined, but with much more difficulty than many other aluminum alloys.

| Alloy Comparison | Description |
| Compared to 3003 Aluminum Alloy: Higher Corrosion Resistance | 5005 aluminum alloy has better corrosion resistance compared to 3003 aluminum alloy, mainly due to the presence of magnesium (1.0%) in 5005, while 3003 mainly contains manganese (1.0-1.5%). Magnesium helps significantly improve the corrosion resistance of the aluminum alloy, making 5005 aluminum plate more resistant to corrosion in humid or marine environments. Thanks to its higher corrosion resistance, 5005 aluminum alloy is commonly used in industries such as construction, shipbuilding, and chemical treatment, while 3003 is mainly used in lighter environments, such as kitchen equipment and roofing materials. |
| Compared to 5052 Aluminum Alloy: Lower Strength, But Better Formability | 5005 aluminum alloy has lower strength compared to 5052 aluminum alloy, as 5052 contains more magnesium (2.5%), making it stronger than 5005. Despite the lower strength of 5005, it excels in formability, especially in cold working and deep drawing processes, where 5005 is easier to process and is ideal for applications requiring complex shaping. In contrast, 5052 aluminum alloy is better suited for applications requiring high strength, high pressure resistance, and fatigue resistance, such as automobile bodies and fuel tanks. |
One of the standout features of 5005 aluminum plate is its anodizing capability. After anodizing, it forms a uniform and aesthetically pleasing surface, which is particularly important for decorative and architectural applications. However, for applications where a flawless surface is critical, it is recommended to specify "Special Anodizing Quality" (AQ) to avoid anodizing streak issues.
Haomei Aluminum has a large inventory of 5005 (anodizing quality) plates, as well as 5005 aluminum mill finish coils and 5005 anodized coils.
5005 aluminum plates are often used as conductors, cookware, dashboards, building materials, interior and exterior materials, vehicle interior materials, anodized parts, etc.
