Comparison of Different Aluminum Alloy Sheets
| Alloy Series | Main Components | Key Characteristics | Ideal Applications |
|---|---|---|---|
| 1xxx Series (e.g., 1060) | Pure Al (≥99.6%) | Excellent electrical/thermal conductivity, high corrosion resistance, but low strength. | Conductive materials, heat sinks, packaging, reflectors. |
| 3xxx Series (e.g., 3003) | Al-Mn (1.0% Mn) | Superior weather resistance, good weldability, 15%~20% higher strength than pure Al. | Building curtain walls, roof panels, marine interiors. |
| 5xxx Series (e.g., 5052) | Al-Mg (2.5% Mg) | Excellent seawater corrosion resistance, high plasticity, stable toughness at low temperatures. | Marine engineering, pressure vessels, shipbuilding. |
| 6xxx Series (e.g., 6061) | Al-Mg-Si (1.0% Mg+0.6% Si) | Balanced performance, high strength (heat-treatable), good machinability and weldability. | Construction frames, automotive parts, aerospace structures. |
| 7xxx Series (e.g., 7075) | Al-Zn-Mg-Cu (5.6% Zn) | Highest strength (super-hard alloy), but poor corrosion resistance (requires surface treatment). | Aerospace components, high-end molds, racing parts. |
Mechanical Property Comparison (Typical Values)
| Property | 1100-H14 | 3003-H14 | 5052-H32 | 6061-T6 |
| Tensile Strength (MPa) | 110-145 | 145-195 | 215-260 | 290-325 |
| Yield Strength (MPa) | 95 | 125 | 165 | 240 |
| Elongation (%) | 5-9 | 8-12 | 10-14 | 10-15 |
| Hardness (Brinell) | 32 | 40 | 60 | 95 |
Key Differences
- Strength: 5052 > 3003 > 1100 > 1050
- Corrosion Resistance: 5052 ≈ 1050 > 3003 > 1100
- Conductivity: 1050 > 1100 > 3003 > 5052
- Cost: 1050 < 1100 < 3003 < 5052
Surface Treatment Options
- Anodizing:
Enhances corrosion resistance and appearance (e.g., clear or colored finishes). - Electrophoretic Coating:
Provides a smooth, durable protective layer for decorative applications. - Powder Coating:
Offers high resistance to scratches and chemicals, ideal for outdoor use. - Brushing/Mirror Polish:
Creates a matte or reflective surface for aesthetic purposes. - Pre-Painting:
PVDF or PE coatings for UV resistance and color customization.
How to Choose the Right Aluminum Sheet?
✅ For electrical or thermal applications → 1060 is ideal due to its high conductivity.
✅ For higher strength needs → consider 3003 or 5052.
✅ For architectural decoration → 1060 is perfect thanks to good surface finish and formability.
✅ For welding or marine applications → 5052 or 6061 would be a better fit.
