Corrosion Resistance 5005 Aluminum Alloy Plate Used For Construction Material
5005 aluminum alloy is a medium-magnesium content (0.5-1.1%) non-heat-treatable 5xxx
series alloy, offering excellent corrosion resistance, good formability, and weldability. Its low-
copper composition makes it particularly suitable for humid or chemical environments, while
maintaining superior surface treatment capabilities (e.g., anodizing).
Properties of 5005 Aluminum Coil
Composition:
Primary alloying element: Magnesium (Mg, 0.5–1.1%), with trace manganese (Mn ≤0.2%).
Low copper (Cu ≤0.2%) and iron (Fe ≤0.7%), ensuring excellent corrosion resistance.
Mechanical Properties (H32 temper example):
Tensile strength: 145–185 MPa
Yield strength: ≥115 MPa
Elongation: ≥5%
Physical Characteristics:
Density: 2.7 g/cm³ (similar to pure aluminum).
Conductivity: ~50% of pure aluminum (good for electrical/thermal applications).
Corrosion Resistance:
Outstanding in marine and industrial environments due to low Cu content.
Common Tempers
| Temper | Treatment Process | Characteristics & Applications |
| O | Annealed | Softest state; suited for deep forming. |
| H12 | Partially hardened (~25% CW) | Balanced strength/formability (general sheet metal). |
| H14 | Half-hard (~50% CW) | Moderate strength (architectural panels). |
| H32 | Stabilized (H22 + low-temp anneal) | Stress-corrosion resistant (outdoor use). |
| H34 | Hard (~75% CW) | Higher-strength parts (e.g., vehicle trim). |
Key Advantages
Superior Corrosion Resistance:
Outperforms copper-containing alloys (e.g., 2xxx/7xxx) in humid/chemical environments.
Excellent Formability:
Easily stamped, bent, or deep-drawn (O or H2x tempers).
Surface Treatment Compatibility:
Anodizes uniformly, ideal for decorative uses (e.g., architectural interiors).
Weldability:
Compatible with TIG/MIG welding; minimal strength loss post-welding.
Primary Applications
♦ Architecture:
Roofing/wall cladding (weather-resistant).
Ceilings, curtain walls (anodized for aesthetics).
♦ Transportation:
Marine interiors (saltwater-resistant), truck liners.
♦ Appliances & Electronics:
Refrigerator/AC panels, electronics enclosures.
♦ Packaging:
Food containers, caps (non-toxic + corrosion-resistant).
Company Advantages
