5754 Aluminum Bar Rod
5754 aluminum bar is a medium-strength wrought aluminum-magnesium alloy belonging to the 5000 series. Known for its excellent corrosion resistance, good weldability, and high fatigue strength, 5754 is widely used in industries where reliability under challenging environmental conditions is critical. The main alloying elements are magnesium (approximately 2.6–3.6%) and small controlled additions of manganese, which enhance strength and resistance to stress-corrosion cracking without significantly compromising ductility.
One of the standout features of 5754 is its exceptional resistance to seawater and atmospheric corrosion, making it a top choice for marine structures, shipbuilding components, and offshore installations. The protective oxide layer formed naturally on the surface effectively prevents further oxidation, even in chloride-rich environments. In addition, 5754 shows strong resistance to many industrial chemicals and weathering effects, ensuring long service life with minimal maintenance.
5754 aluminum bar combines strength, corrosion resistance, and ease of fabrication. Therefore, it is extensively specified for pressure vessels. It is also used for vehicle bodies and bridge components. Other applications include storage tanks and marine hardware. It is also used in architectural structures.

Corrosion Resistance of HSTF 5754 Aluminum Bar
- Excellent Seawater Corrosion Resistance
5754 aluminum alloy belongs to the Al-Mg alloy family, containing 2.6-3.6% magnesium. In marine environments, it forms a dense oxide film, effectively resisting the erosion of seawater and salt spray. Its corrosion resistance is far superior to ordinary carbon steel, with a corrosion rate in seawater only 1/10 to 1/20 that of carbon steel.
- Good Resistance to Pitting and Crevice Corrosion
This alloy is not prone to pitting and crevice corrosion in marine environments, making it particularly suitable for welded structures and riveted joints in ships—areas prone to water accumulation.
- Control of Galvanic Corrosion in Contact with Dissimilar Metals
In marine applications, 5754 aluminum alloy often comes into contact with dissimilar metals such as stainless steel and copper alloys. Through proper insulation treatment and coating protection, the method can effectively control galvanic corrosion.
- Corrosion Resistance in Welded Areas
5754 aluminum alloy has good weldability. The corrosion resistance of the welded joint area is comparable to that of the base material, and its corrosion resistance remains largely unaffected by the heat-affected zone of welding.
- Ready to Use Without Surface Treatment
In typical marine environments, 5754 aluminum alloy can serve directly without additional anti-corrosion coatings, significantly reducing maintenance and operating costs.
These properties make 5754 aluminum alloy an ideal material choice for marine engineering applications such as ship decks, hull structures, and outfitting components.
Comparison of Corrosion Resistance with Other Marine Aluminum Alloys
| Alloy | Description | Ship Application Scenarios |
| 5052 | With the lowest magnesium content, a more uniform oxide film composition, and the weakest susceptibility to stress corrosion cracking (SCC), it exhibits a corrosion rate of <0.01 mm/year in seawater and maintains excellent corrosion resistance even after 5 years of exposure. Its Cr content is 0.15-0.35%, which allows it to form a diffusely distributed Cr-rich second phase, effectively hindering the expansion of intergranular corrosion channels, making it particularly suitable for humid atmospheric and freshwater environments. | Suitable for low-load components such as marine sheet metal parts, instrument brackets, and street light brackets, especially suitable for marine environments with extremely high corrosion resistance requirements. |
| 5754 | With a magnesium content between 5052 and 5083, it belongs to the medium-strength aluminum alloy category and possesses good corrosion resistance, weldability, and processability. In ship structures, it finds main use in parts requiring medium strength and high corrosion resistance, such as ship structures and offshore facilities, and transport tanks. | Widely used in welded structures, storage tanks, pressure vessels, ship structures, and other applications requiring moderate strength and excellent corrosion resistance. |
| 5083 | The highest magnesium content significantly improves strength, but Mg₂Al₃ precipitates easily form at grain boundaries, leading to slightly higher susceptibility to stress corrosion cracking. Optimizing the rolling process or annealing treatment is needed to reduce precipitate segregation and improve corrosion resistance. The 5083-H32 temper exhibits a fatigue strength of 140 MPa after 10⁷ cycles; surface shot peening can improve fatigue strength by 15%-20%. | Primarily used in heavy-load structural components such as ship hulls and offshore platforms, its high strength and excellent weldability make it one of the preferred materials for shipbuilding. |
All three alloys have good resistance to seawater corrosion, but 5052 performs best in terms of corrosion resistance, 5083 is superior in terms of strength, and 5754 achieves a balance in overall performance. Users can choose according to the strength, corrosion resistance and cost requirements of specific application scenarios.
