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

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 (ideal for long-term outdoor use).

Better than 6xxx alloys (e.g., 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 6xxx alloys).

Can be rolled, bent, and stamped into complex shapes.

(4) Compliance with European Standards

Meets EN 573-3 and EN 485 standards.

Preferred over 5052 in Europe due to better mechanical properties.
