Al Mg Alloy EN AW 5754 Aluminium Alloy Plate Automotive Body Panel
5754 alloy is a non-heat-treatable aluminum-magnesium alloy, widely used for automotive production,
particularly for body panel and structural component. It offers an excellent balance of strength,
formability, and corrosion resistance.
Our Company
♦ We had streamlined and standardized our workflows so everyone can work together more smoothly,
avoid any mistake, and get more done.
♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,
fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth
motivation, while enhancing team cohesion and a sense of belonging.
♦ Left 1--this is what I look like — nice to meet you here.
Our Factory
1) We introduced world-leading technology and equipment, including advanced vertical intelligent
storage, logistics systems, and finishing lines, to meet all production demands for aluminum plates,
coils and strips.
1) We have built portfolio advantages with multiple products, and we are good at big size and mass
production.

Common Tempers for Automotive Applications
For automotive body panel applications, the most common tempers for 5754 aluminum are the
H2x (e.g., H22, H24, H26)
H22 : 1/4 hard. Offers good formability with moderate strength.
H24 : 1/2 hard. This is the most typical and frequently used temper. It provides the best balance
of strength, and formability, making it ideal for stamping parts like doors, hoods, and fenders.
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 |
Comparative Process Analysis
Process Stage | 5754 (Al-Mg) | 6061 (Al-Mg-Si) |
Formability | Excellent | Requires annealing |
Weldability | Superior (no cracking) | Needs PWHT |
Surface Treatment | Lower cost | Moderate cost |
Weight Reduction | 60%+ vs steel | 60%+ vs steel |
Why Europe Prefers 5754 Over 5052
• Higher Magnesium Content (~3% Mg vs. 5052’s 2.2–2.8%) → Better corrosion resistance.
• Stricter Environmental Standards → 5754 complies with EU regulations.
• Superior Weld Integrity → Less cracking risk than 5052 in critical joints.
