EN AW 5754 Aluminum Alloy For Automotive Dashboard Bracket
5754 aluminium is a widely used 5000 series aluminum alloy in Europe and other regions for
enclosed trailers (cargo trailers, caravans, etc). It offers an excellent balance of strength, wel
-dability, and corrosion resistance, make it ideal for structural and non-structural trailer components.
Key Characteristics
Material Composition:
Al-Mg alloy (2.6–3.6% Mg), non-heat-treatable (strengthened by cold working).
Corrosion resistance:
Superior to 6xxx series (no intergranular corrosion risk), ideal for humid/salty environments.
Weldability:
Excellent (MIG/TIG welding retains >90% strength).
Mechanical Properties (Typical Tempers)
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
| O | 220–260 | 80–120 | ≥15 |
| H32 | 270–320 | 150–200 | ≥10 |
Advantages for Dashboard Stand
✅ Lightweight: Density = 2.7 g/cm³ (50%+ lighter than steel).
✅ Vibration resistance: High toughness, resists cracking under long-term road vibrations.
✅ Chemical resistance: Withstands oil, brake fluid, and coolants (better than 5052).
✅ Ease of fabrication:
Easy stamping (O temper for complex shapes).
No heat treatment needed (H32 temper balances strength/formability).

Comparative Process Analysis
| Process Stage | 5754 (Al-Mg) | 6061 (Al-Mg-Si) | Steel Brackets |
| Formability | Excellent | Requires annealing | High tonnage required |
| Weldability | Superior (no cracking) | Needs PWHT | Requires rustproofing |
| Surface Treatment | Lower cost | Moderate cost | High cost |
| Weight Reduction | 50%+ vs steel | 45%+ vs steel | Baseline |
Why Europe Prefers 5754 Over 5052
• Higher Magnesium Content (~3% Mg vs. 5052’s 2.2–2.8%) → Better corrosion resistance.
• Stricter Environmental Standards (e.g., REACH) → 5754 complies with EU regulations.
• Superior Weld Integrity → Less cracking risk than 5052 in critical joints.
