Corrosion Resistance 5754 Aluminium Plate for Enclosed Trailer
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,
weldability, and corrosion resistance, make it ideal for structural and non-structural trailer
components.
Key Properties of 5754 Alloy
| Property | Value / Description |
| Tensile Strength | 190–240 MPa |
| Yield Strength | 80–180 MPa |
| Elongation | 10–20% (good formability) |
| Density | 2.66 g/cm³ (lightweight) |
| Corrosion Resistance | Excellent (marine-grade performance) |
| Weldability | Very good (MIG/TIG compatible) |
Why 5754 is Used in Enclosed Trailers?
(1) Superior Corrosion Resistance
Contains ~3% Magnesium (Mg), forming a protective oxide layer.
Resists salt, humidity, and road chemicals.
Better than 6xxx alloys (eg., 6061) in harsh environments.
(2) Good Strength-to-Weight Ratio
Stronger than 5052 but lighter than steel.
Suitable for walls, roofs, and flooring without excessive weight.
(3) Excellent Weldability & Formability
Easily welded (no cracking issues, unlike 6000 series alloys).
Can be rolled, bent, and stamped into complex shapes.
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.
Comparison with Other Trailer Alloys
| Alloy | Best For | vs. 5754 |
| 5052 | Non-structural panels (North America) | Cheaper but weaker |
| 6082-T6 | High-stress frames (EU) | Stronger but less corrosion-resistant |
| 5083 | Marine/off-road trailers | Stronger than 5754, but more expensive |
