In industrial applications, 5052 and
5754 aluminum plates are two common aluminum alloy materials, each with unique properties suited for different scenarios. Below, we compare their differences in hardness, elongation, chemical performance, and applications.
1. Hardness Comparison
The
5052 aluminum plate is a medium-strength alloy with a tensile strength of 210-230 MPa, about 100% higher than pure aluminum (e.g., 1060 aluminum, which ranges at 110-130 MPa). This makes 5052 ideal for high-strength applications.
The 5754 aluminum plate offers the highest strength among non-heat-treatable alloys. While slightly lower in hardness than 5052, its balanced mechanical properties excel in welded structures and pressure vessels.
2. Elongation and Workability
5052 has an elongation rate of 12%-20%, far exceeding 1060’s 5%, making it more ductile for stamping or bending.
5754 also features excellent workability. Its surface can be brushed, sandblasted, or polished for high-end finishes, ideal for aesthetic applications.
3. Chemical Properties & Corrosion Resistance
5052, as an alloy (with magnesium), outperforms pure aluminum (e.g., 1060) in corrosive environments like humidity or salt spray.
5754 boasts superior corrosion resistance, especially in marine settings (e.g., ships, offshore structures), coupled with excellent weldability and minimal post-weld corrosion.
4. Primary Applications
5052: Electronics casings, architectural decor, and automotive interiors requiring strength and formability.
5754: Pressure vessels, transport tanks, shipbuilding, and chemical equipment due to its fatigue strength, weldability, and corrosion resistance.
Conclusion
5052 suits high-hardness and forming needs, while 5754 excels in corrosion resistance and welded structures. Choose 5052 for cost efficiency or 5754 for harsh environments and critical welding projects.
