Corrosion Resistance EN AW-5754 (AlMg3) Aluminum Alloy for Enclosed Trailers
EN AW-5754 (equivalent to AlMg3) is a widely used 5xxx-series aluminum alloy in Europe
and other regions for enclosed trailers (cargo trailers, caravans, etc.). It offers an excellent
balance of strength, corrosion resistance, and weldability, making it ideal for structural and
non-structural trailer components.
Key Properties of 5754 Alloy
| Property | Value / Description |
| Tensile Strength | 190–240 MPa (H22/H24 temper) |
| Yield Strength | 80–180 MPa (depending on temper) |
| 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?
Contains ~3% Magnesium (Mg), forming a protective oxide layer.
Resists salt, humidity, and road chemicals (ideal for long-term outdoor use).
Better than 6xxx alloys (e.g., 6061) in harsh environments.
Stronger than 5052 but lighter than steel.
Suitable for walls, roofs, and flooring without excessive weight.
Easily welded (no cracking issues, unlike 6xxx alloys).
Can be rolled, bent, and stamped into complex shapes.
Meets EN 573-3 and EN 485 standards.
Preferred over 5052 in Europe due to better mechanical properties.
Comparison with Other Trailer Alloys
