EN AW 5754 Aluminum Alloy For Automotive Dashboard Bracket

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)

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

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.
