Mirror alloy aluminum plate
Mirror alloy aluminum plate is a premium-grade aluminum product known for its exceptional surface finish, mechanical properties, and versatility. Engineered to provide a brilliant reflective surface resembling a mirror, this aluminum plate serves various high-end applications requiring both aesthetic appeal and structural integrity. The alloy composition and specialized processing techniques enable its distinctive high gloss, smooth texture, and robust performance, making it an optimal choice in industries such as automotive, architecture, electronics, and decorative arts.
Features of Mirror Alloy Aluminum Plate
1. Superior Surface Finish
- Mirror-like shine: Precision polishing and surface treatment processes give this aluminum plate a lustrous reflective surface with minimal surface roughness (Ra ≤0.2 μm).
- Corrosion resistance: Treated with protective coatings or anodized to resist oxidation and maintain appearance over long periods.
- Scratch and stain resistance: Advanced surface hardening techniques reduce fingerprints, smudges, and minor abrasion impacts.
2. Mechanical Properties
| Property | Typical Value | Test Method |
|---|---|---|
| Density | 2.7 g/cm³ | ASTM B311 |
| Tensile Strength | 130 - 300 MPa | ASTM B359 |
| Yield Strength | 70 - 250 MPa | ASTM E8 |
| Elongation at Break | 8-25% | ASTM B557 |
| Hardness (HV) | 40 - 120 | ASTM E384 |
- Lightweight: High strength-to-weight ratio suitable for applications where weight reduction is key.
- Good machinability and formability: Easy to cut, drill, punch, and form into complex shapes while retaining mirror finish.
3. Chemical Composition and Alloy Type
Mirror alloy aluminum plates commonly employ specific alloys that allow both mechanical strength and excellent finishability, such as 1100, 3003, and occasionally higher strength alloys like 5005.
| Element | 1100 Alloy (%) | 3003 Alloy (%) | 5005 Alloy (%) |
|---|---|---|---|
| Aluminum (Al) | 99.0 min | 97.0 min | 97.0 min |
| Copper (Cu) | 0.05 max | 0.10 max | 0.20 max |
| Manganese (Mn) | 0.05 max | 1.0 - 1.5 | 0.20 - 0.7 |
| Magnesium (Mg) | 0.05 max | 0.05 max | 0.5 - 1.1 |
| Silicon (Si) | 0.95 max | 0.6 max | 0.3 max |
| Iron (Fe) | 0.95 max | 0.7 max | 0.7 max |
| Zinc (Zn) | 0.1 max | 0.1 max | 0.25 max |
The high purity of base aluminum alloys like 1100 offers superior brightness, while elements like manganese and magnesium enhance hardness and structural strength especially in 3003 and 5005 variants.
