Product Overview
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 provides superior corrosion resistance compared to 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, with good corrosion resistance while maintaining the same safety and crashworthiness as before, resulting in economic fuel consumption and minimum 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).
