5052 Alloy Aluminium Plate Manufacturer Used For Automotive Access Door
5052 is a non-heat-treatable aluminum-magnesium alloy (5xxx series) known for its excellent
corrosion resistance, good formability, and weldability. It's widely used in marine, automotive,
construction, and electronic applications.
Key Characteristics
Composition
Primary: Al (balance) + Mg (2.2-2.8%) + Cr (0.15-0.35%)
Low Cu/Fe content → Superior corrosion resistance vs. copper-containing alloys (e.g., 2024).
Performance Highlights
♦ Corrosion Resistance:
Excellent saltwater/chemical resistance, ideal for underbody panels or wet climates.
♦ Formability:
Moderate strength (O/H32 tempers) allows deep drawing and bending (e.g., curved panel edges).
♦ Weldability:
Compatible with MIG/TIG welding; no post-weld heat treatment required (unlike 6xxx alloys).
♦ Weight:
Density: 2.68 g/cm³ (~65% lighter than steel).
Advantages for Access Door
✅ Dent Resistance: H32/H34 tempers (YS: 180-230 MPa) withstand minor impacts.
✅ Surface Finish Options:
Anodizing (aesthetic) or painting (color-matching).
✅ Cost-Effectiveness:
More affordable than 6xxx (e.g., 6061) and 7xxx (e.g., 7075) series.
✅ Durability:
Resists oil, detergents, and oxidation over long-term use.
Comparison with Alternative Alloys
| Alloy | Pros | Cons | Best For |
| 5052 | Corrosion/weld/cost balance | Lower strength than 6xxx/7xxx | High-volume access panels |
| 6061 | Higher strength (T6) | Requires heat treatment | Structural parts (non-door) |
| 3003 | Lower cost, more ductile | Low strength (dents easily) | Interior trim |
| 7075 | Ultra-high strength | Poor corrosion resistance | Racing/military vehicles |
Critical Metrics:
Strength: 7075 > 6061 > 5052 > 3003
Corrosion Resistance: 5052 ≈ 3003 > 6061 > 7075
Cost: 7075 > 6061 > 5052 > 3003

Aluminum-made alloy plate is much lighter than iron, good corrosion resistance with same safety
and crashworthiness as before, and economic fuel consumption and mininum CO2 discharge.
Real-World Applications
EVs: Tesla battery access covers (5052-H32 for lightweighting + rustproofing).
Trucks: Volvo truck service panels (5052-H34 for dent resistance + weldability).
