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.
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.
2)In the future, we will focus on creating value for customers,
caring for employees, and serving
society, striving to become a global leader in high end flat-rolled
products.
We use the World-advanced Equipments
| Code | Name | Brand |
| a | aluminum ignot melting furnace | GAUTSCHI (Switzerland) |
| b | 2800mm width single stand cold rolling mill | SMS Group (Germany) |
| c | 4 continuous hot rolling mills | SMS Group (Germany) |
| d | heavy crop and dividing shear | SMS Group (Germany) |
| e | coil material annealing furnace | SMS Group (Germany) |
| f | all automatic three-dimensional elevated warehouse | Dematic (USA) |
These are some samples we made below :
Ocean Shipping
For oversize sheet, we use Flat Rack Container
1) We use suitable securing material, such as wooden blocks, steel
straps, and ratchet tie-downs
to firmly fix the aluminum plates to the flat rack.
2) To prevent possible exposure to seawater or rain, we cover the
entire cargo with waterproof tarps.
3) We make sure these sheets are loaded with a low and evenly
distributed center of gravity to avoid
tilting during the transportation.
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 |
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
| Process Stage | 5754 (Al-Mg) | 6061 (Al-Mg-Si) | Steel Brackets |
| Formability | Excellent | Requires annealing | High tonnage required |
| Weldability | Superior (no cracking) | Needs PWHT | Requires rustproofing |
| Surface Treatment | Lower cost | Moderate cost | High cost |
| Weight Reduction | 50%+ vs steel | 45%+ vs steel | Baseline |
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.
