1070 mirror aluminum has higher purity (≥99.7%) compared to 1060 (≥99.6%), which results in slightly better reflectivity and surface clarity. However, both alloys are widely used for mirror aluminum sheets depending on cost and performance requirements.
For purchasing managers and engineers, choosing between wholesale 1070 aluminum sheet and 1060 aluminum coil is a frequent debate. While the 0.1% difference in purity seems small on paper, it affects the final surface finish, the manufacturing cost, and the end product's optical performance. As a direct bulk aluminum supplier, GNEE provides this straightforward technical comparison to help you make the right purchasing decision for your production line.
Common Applications for 1070 and 1060 polished Aluminum sheet
Before comparing their differences, it is important to know that both grades belong to the pure aluminum series (1000 series) and share excellent corrosion resistance, high thermal conductivity, and good formability.
Both 1070 and 1060 aluminum are widely used in mirror surface applications such as lighting and decoration.
Typical applications include:
- LED lighting reflectors: Standard commercial downlights, fluorescent tube housings, and industrial high-bay lighting.
- Solar reflective systems: Parabolic troughs and solar collector panels.
- Architectural decoration: Interior wall panels, elevator cabins, and suspended ceiling grids.
- Appliance panels: Heat-reflective boards for ovens and decorative trims for refrigerators.
- Industrial reflectors: Heat shields and optical equipment housings.
Core Differences of 1070 vs 1060 Aluminum
| Element | 1070 Aluminum | 1060 Aluminum |
| Aluminum (Al) | ≥ 99.7% | ≥ 99.6% |
| Iron (Fe) | ≤ 0.25% | ≤ 0.35% |
| Silicon (Si) | ≤ 0.20% | ≤ 0.25% |
Higher purity in 1070 results in fewer impurities, which improves mirror surface uniformity after polishing. Impurities like iron can create microscopic hard spots. When the metal passes through the mechanical polishing rollers, these hard spots do not polish as smoothly as pure aluminum, which can lead to minor visual defects on the mirror surface.
Performance Comparison of 1070 vs 1060 Mirror Aluminum
Because of the chemical differences, the final reflective surface behaves slightly differently when processed under the exact same conditions.
| Property | 1070 Mirror Aluminum | 1060 Mirror Aluminum |
| Reflectivity | 88% – 90% | 85% – 88% |
| Surface clarity | Higher (Optical grade) | Very good (Commercial grade) |
| Defect sensitivity | Lower | Slightly higher |
| Polishing result | More consistent | Stable |
1070 aluminum provides slightly better mirror clarity and reflectivity, while 1060 offers a balanced and cost-effective solution for standard manufacturing.
Mechanical Properties of 1070 vs 1060 Mirror Aluminum
For factories stamping or bending these sheets into complex reflector shapes, mechanical properties are just as important as the mirror finish. If the material cracks during stamping, the reflectivity does not matter.
| Property | Typical 1070 Aluminum | Typical 1060 Aluminum |
| Tensile Strength | 60 – 95 MPa | 70 – 110 MPa |
| Elongation | 25% – 45% | 20% – 40% |
| Formability | Excellent | Excellent |
1060 is slightly stronger, while 1070 is softer and more suitable for high-gloss mirror polishing. The slightly higher tensile strength of 1060 means it resists minor dents and handling damage slightly better during high-speed automated mass production. 1070, being softer, requires more careful handling but is easier to deep-draw into tight parabolic shapes.
Key Purchasing Decision Logic
How do you decide which wholesale aluminum sheet to order from GNEE? Use this straightforward logic based on your final product requirements.
If your project requires:
- Higher reflectivity (maximizing lumen output)
- Premium surface appearance with zero optical distortion
- Optical consistency for high-end or medical equipment
Choose 1070 mirror aluminum.
If your project requires:
- Cost efficiency and strict budget control
- Stable mass production for standard commercial items
- General reflective use where the mirror serves a functional rather than decorative purpose
Choose 1060 mirror aluminum.
Visual Differences bewteeh polished 1070 sheet and 1060 sheets
The difference in reflectivity is subtle in general use but becomes more noticeable in high-end lighting applications.
To the naked human eye under normal room lighting, both sheets look like highly reflective mirrors. However, if you are manufacturing LED street lights or industrial high-bay fixtures, a lux meter will detect the 2% to 3% difference in light output. Furthermore, if the mirror aluminum is used for architectural ceiling panels, 1070 will reflect the surrounding environment with slightly sharper clarity and less distortion (less "orange peel" effect) than 1060.
Processing Quality
Mirror quality is not only determined by the alloy grade but also by:
- Rolling surface quality: The raw aluminum coil must be rolled perfectly flat. Any waves or thickness variations will distort the mirror reflection.
- Polishing precision: The pressure, speed, and compounds used in the mechanical buffing process dictate how bright the final mirror will be. A well-polished 1060 sheet will always look better than a poorly polished 1070 sheet.
- Surface protection film: Applying a high-quality PE (polyethylene) film prevents scratches during slitting and shipping.
At GNEE, we ensure that both our 1070 and 1060 wholesale mirror aluminum sheets are processed with identical high-precision polishing lines and packed with export-grade moisture-proof materials to guarantee perfect surface condition upon arrival.
Export Packaging for Mirror Aluminum Orders
- PE Film Lamination: Every mirror surface is covered with an easy-to-peel protective film.
- Moisture Barrier: The aluminum sheets or coils are wrapped in waterproof kraft paper to block salty sea air.
- Desiccant Packets: Moisture absorbers are placed inside the wrapping to prevent condensation and white oxidation spots.
- Seaworthy Pallets: The wrapped metal is securely strapped to fumigated wooden pallets to prevent shifting inside the shipping container.
Sourcing the correct raw material is about balancing your technical requirements with your budget. Instead of focusing only on alloy differences, the final performance depends on your application, reflectivity requirement, and surface treatment process.
We can help you select the most suitable mirror aluminum grade (1070 or 1060) based on your project needs. GNEE is ready to support your factory with reliable quality, custom sizes, and competitive wholesale pricing.
