1060 h112 polished aluminum sheets plates
1060 H112 polished aluminum sheets and plates are a practical choice when you need high purity aluminum, excellent corrosion resistance, and a bright, clean surface that performs well in both decorative and functional environments. Built on the 1xxx series foundation, 1060 aluminum is valued for its very high aluminum content, dependable formability, and stable performance in general industrial conditions. The H112 temper provides a controlled "as-fabricated" strength level, commonly used for hot-rolled plate and sheet where moderate mechanical properties and good workability are required.
Polishing upgrades the surface from purely industrial to visually refined, helping the material serve as a base for reflectors, trims, interior panels, signage, and other projects where appearance and cleanliness matter-without losing the inherent advantages of a high-purity aluminum alloy.
What "1060" and "H112" Mean in Real Use
1060 aluminum is a high-purity alloy with minimal alloying additions. This makes it especially attractive for applications that benefit from aluminum's natural properties-corrosion resistance, conductivity, and easy fabrication.
H112 is a temper often applied to products that have received some amount of thermal and/or mechanical processing during manufacture. Compared with fully annealed "O" temper, H112 typically offers slightly higher strength while preserving good forming behavior. It's frequently specified for plate because it balances stability, workability, and cost.
Polished finish typically refers to mechanically improved surface appearance. The level of polish can be tailored-ranging from a bright industrial polish to more mirror-like finishes-depending on the abrasives and process route used.
Features of 1060 H112 Polished Sheet/Plate
High corrosion resistance with a clean surface
1060's purity supports strong resistance to atmospheric corrosion, and polishing can further improve perceived surface cleanliness for visible parts. In many indoor and mild outdoor environments, it maintains a bright aluminum appearance with standard care.
Excellent formability and fabrication friendliness
1060 is well known for bending, rolling, and general forming. H112 keeps the material stable for industrial fabrication while remaining friendly to common shop operations such as shearing, sawing, routing, drilling, and forming (with sensible bend radii).
High reflectivity and strong aesthetic potential
Polishing increases reflectivity and surface uniformity, enabling decorative panels, light reflectors, appliance facings, and architectural accents where a metallic "premium" look is desired.
High electrical and thermal conductivity
High-purity aluminum is naturally conductive. This supports use in busbar-related claddings, conductive housings, heat spreaders, and thermal management components where moderate strength is acceptable and corrosion resistance is valuable.
Lightweight with good recyclability
Like all aluminum products, 1060 sheet/plate delivers an excellent strength-to-weight advantage for non-structural roles and remains highly recyclable-useful for customers with sustainability targets.
Chemical Composition (Typical Limits)
The chemical makeup of 1060 is the core reason for its behavior: purity-driven corrosion resistance, conductivity, and forming performance.
| Element | Typical Limit / Range (wt.%) |
|---|---|
| Aluminum (Al) | ≥ 99.60 |
| Silicon (Si) | ≤ 0.25 |
| Iron (Fe) | ≤ 0.35 |
| Copper (Cu) | ≤ 0.05 |
| Manganese (Mn) | ≤ 0.03 |

| Others (each) | ≤ 0.03 |
| Others (total) | ≤ 0.10 |
Note: Exact limits may vary slightly by standard and mill practice. Always confirm with a mill test certificate for critical projects.

Why Polishing Matters (Beyond Appearance)
Polishing is not only visual-it influences how the material behaves in the customer's workflow.
| Benefit | What it does for your project |
|---|---|
| Enhanced reflectivity | Useful for lighting components, reflectors, and bright decorative surfaces |
| Improved surface uniformity | Better cosmetic consistency for panels, trims, and visible covers |
| Easier cleaning | Smoother surfaces tend to retain less dirt and simplify wipe-down |
| Better base for finishing | A consistent polished surface can improve results for clear coating, anodizing, or protective films |
Practical note: Polished aluminum is more sensitive to handling marks. Protective films, paper interleaving, and clean gloves are strongly recommended during fabrication.
Applications: Where 1060 H112 Polished Sheet/Plate Performs Best
Architectural and interior decoration
Polished 1060 is frequently selected for interior panels, decorative trims, column wraps, ceilings, and feature surfaces that need a bright metallic look without the cost and complexity of high-strength alloys. For outdoor architecture, surface protection (clear coat, anodizing, or laminated film) helps preserve appearance.
Signage, display, and retail fixtures
The combination of easy fabrication and a bright surface makes it suitable for sign backers, display panels, brand fixtures, and reflective accents. It cuts cleanly, forms well, and supports consistent surface presentation when protected during processing.
Lighting reflectors and optical-style components (non-precision)
High-purity aluminum is known for reflectivity. With an appropriate polish level, 1060 can be used for lamp housings, reflector panels, and light-guiding surfaces where ultra-precise optical tolerances are not required.
Appliance, equipment covers, and protective panels
For machine covers, equipment cladding, cleanroom-friendly panels, and protective guards, 1060 H112 offers corrosion resistance and a neat appearance. It is particularly attractive when the component is more about shielding and aesthetics than structural load.
Thermal management and heat spreading
While 1060 is not a high-strength structural alloy, its thermal conductivity supports heat spreader plates, thermal shields, and heat distribution panels where corrosion resistance and lightweight construction are valued.
Chemical and corrosion-resistant environments (mild to moderate)
High-purity aluminum performs well in many general environments. For chemical exposure, compatibility should be confirmed, but 1060 is commonly considered when the priority is corrosion resistance and cleanability.
Fabrication Notes and Customer Tips
| Process | Recommendation |
|---|---|
| Cutting | Use sharp tooling; protect the polished face with film to prevent scratches |
| Bending/Forming | Use suitable bend radii; avoid surface galling with clean dies and lubrication |
| Welding | Generally weldable; choose filler and process based on design and appearance needs |
| Surface protection | Consider PVC film, paper interleave, or clean-pack for visible surfaces |
| Finishing | Works well with clear coating and anodizing; confirm polish/anodize compatibility |
When to Choose 1060 H112 Polished (and When Not To)
Choose it when you need a bright, polished aluminum look, excellent corrosion resistance, high conductivity, and easy forming at an efficient cost.
Consider other alloys when your project requires high structural strength, high wear resistance, or heavy-load bearing performance. In those cases, 5xxx or 6xxx series alloys may be more suitable-though often with different surface and forming behavior.
