Aa 5754 aluminum plate
AA 5754 aluminum plate is a high-quality alloy widely used for its excellent combination of mechanical properties, corrosion resistance, and formability. As a prominent member of the 5xxx series aluminum alloys, 5754 is primarily alloyed with magnesium (Mg) which significantly enhances its strength and corrosion resistance without sacrificing its ease of fabrication. This makes AA 5754 aluminum plate an ideal candidate for a variety of industrial and commercial applications.
Chemical Composition
The AA 5754 alloy conforms to the following chemical composition as per ASTM B209 and EN 485 standards:
| Element | Typical Composition (wt.%) |
|---|---|
| Aluminum (Al) | Balance |
| Magnesium (Mg) | 3.0 – 3.5 |
| Manganese (Mn) | 0.5 – 1.0 |
| Chromium (Cr) | 0.15 – 0.35 |
| Iron (Fe) | ≤ 0.4 |
| Silicon (Si) | ≤ 0.4 |
| Copper (Cu) | ≤ 0.1 |
| Zinc (Zn) | ≤ 0.2 |
| Titanium (Ti) | ≤ 0.15 |
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength (MPa) | 200 – 270 |
| Yield Strength (MPa) | 110 – 160 |
| Elongation (%) | 10 – 27 |
| Hardness (Brinell HB) | 55 – 75 |
| Density (g/cm³) | 2.66 |
| Modulus of Elasticity (GPa) | 68.9 |
Note: Mechanical properties can vary slightly depending on temper conditions (e.g., O, H111, H112).
Features
1. Excellent Corrosion Resistance
Due to the magnesium content, 5754 alloy offers outstanding resistance to atmospheric corrosion and seawater environments. It performs well in automotive panels and marine applications, resisting corrosion from salt, humidity, and oxidation.
2. Superior Formability
AA 5754 plates are highly formable, allowing easy bending, stamping, and deep drawing. This property enables manufacturers to produce complex shapes with fine details without cracking.
3. High Strength Among Non-Heat Treatable Alloys
As a non-heat treatable alloy, 5754 achieves strength primarily through strain hardening. It provides a great balance between strength and ductility, outperforming other pure aluminum grades in mechanical performance without forced heat treatments.
4. Good Weldability
5754 aluminum plates can be welded with techniques such as TIG, MIG, and spot welding without special pre-treatment, producing strong and neat welds suitable for structural and load-bearing components.
5. Anodizing Capability
This alloy is excellent for anodizing, as the surface finish enhances both aesthetics and corrosion protection—widely used in architectural and decorative panels.
