1060 H18 anodized mirror aluminum coil
The 1060 H18 anodized mirror aluminum coil is a high-purity, high-reflectivity rolled aluminum product, specially treated to deliver a bright, mirror-like surface with excellent durability. It is widely used in lighting, decoration, solar energy, reflective panels, and a variety of industrial and consumer products where appearance and light control matter.
Aluminum 1060 is a commercially pure aluminum alloy with at least 99.6% aluminum content. The H18 temper indicates it is in a full-hard, cold-worked condition, providing higher strength than fully annealed 1060 while still retaining good formability for certain bending and stamping operations.

Chemical Composition of 1060 Aluminum
As a near-pure aluminum, alloy 1060 contains very low levels of alloying elements. This high purity contributes to excellent corrosion resistance and good electrical and thermal conductivity.
| Element | Typical Max Content (%) | Function / Effect |
|---|---|---|
| Al | Balance (≥ 99.6) | Base metal; high conductivity, corrosion resistant |
| Si | ≤ 0.25 | Slightly improves strength, affects fluidity |
| Fe | ≤ 0.35 | Influences strength and surface finish |
| Cu | ≤ 0.05 | Excess may reduce corrosion resistance |
| Mn | ≤ 0.03 | Trace; minor effect on strength |
| Mg | ≤ 0.03 | Trace; minor effect on strength |
| Zn | ≤ 0.05 | Trace; may influence corrosion behavior |
| Ti | ≤ 0.03 | Grain refinement in some products |
| Others (each) | ≤ 0.03 | Impurities |
| Others (total) | ≤ 0.10 | Impurities |
Exact limits may vary slightly by standard (GB, ASTM, EN) and producer, but the emphasis remains very high aluminum content.
Temper H18 and Mechanical Properties
The H18 temper means the coil is cold-worked to a full-hard condition without subsequent annealing. This raises strength but reduces elongation compared with soft tempers such as O or H14.
Typical mechanical properties for 1060 H18 anodized mirror aluminum coil:
| Property | Typical Value Range | Notes |
|---|---|---|
| Tensile strength Rm | 135 – 165 MPa | Depends on thickness and process |
| Yield strength Rp0.2 | ≥ 115 MPa | Higher than softer tempers |
| Elongation A50 | 1 – 5 % | Lower ductility due to full-hard temper |
| Brinell hardness HB | ~35 – 45 HB | Higher hardness than O temper |
| Modulus of elasticity | ~70 GPa | Similar for most aluminum alloys |
| Density | ~2.70 g/cm³ | Lightweight material |
| Electrical conductivity | ~55–57 % IACS | High due to high Al purity |
| Thermal conductivity | ~230 W/(m·K) | Very good heat conduction |
For demanding forming operations, softer tempers may be preferred, but H18 is well suited to flat panels, reflective plates, and applications requiring stiffness and dimensional stability.
Anodized Mirror Surface Characteristics
The “mirror” finish is achieved through high-quality rolling and polishing, followed by anodizing, which creates a controlled aluminum oxide layer. This combination delivers both high reflectivity and surface protection.
| Surface Parameter | Typical Feature |
|---|---|
| Surface gloss | High-gloss mirror, uniform reflection |
| Reflectivity (specular) | Approx. 80–92% (depending on grade and finish) |
| Anodic film thickness | ~3 – 10 μm (decorative / protective level) |
| Color options | Natural silver, or colored via dyeing/electrocoloring |
| Surface defects | Low; controlled for scratches and rolling marks |
| Stain / corrosion resistance | Improved vs. non-anodized due to oxide layer |
| Cleanability | Easy to clean; suitable for interior and many exterior uses |
Reflectivity values depend on the polishing quality, anodizing process, and specific product series (standard mirror, high-reflective, diffuse-reflective versions).

Processing and Fabrication Considerations
To maintain the mirror quality and structural performance, some fabrication guidelines are recommended:
| Process Step | Recommendation / Note |
|---|---|
| Cutting / slitting | Use sharp, clean tooling; protect surface with film |
| Bending | Observe minimum bend radius; H18 has limited formability |
| Stamping / punching | Avoid deep draws; polish or protect dies to prevent scratches |
| Surface protection | Keep protective PE film on during processing and transport |
| Cleaning | Use neutral detergents; avoid strong alkali/acids that attack anodic layer |
| Bonding / lamination | Compatible with many adhesives; test for adhesion on anodized surface |
For complex deep-forming parts, switching to a softer temper (such as 1060 O or H14) with later anodizing may be more suitable.
Quality Control and Standard Compliance
Reliable 1060 H18 anodized mirror aluminum coil is typically produced under controlled conditions with:
| Control Aspect | Typical Focus Point |
|---|---|
| Dimensional control | Thickness, width, flatness, edge quality |
| Surface inspection | Scratches, streaks, pits, color uniformity |
| Reflectivity testing | Specular and total reflectance |
| Anodic film tests | Thickness, hardness, adhesion, corrosion resistance |
| Mechanical tests | Tensile, yield, elongation according to standards |
Compliance with standards such as ASTM B209, EN 485/573, or national GB/T specifications ensures predictable performance and consistent quality from coil to coil.
The 1060 H18 anodized mirror aluminum coil offers a well-balanced combination of:
- High aluminum purity for conductivity and corrosion resistance
