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

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).
