Product Description1070 industrial pure aluminum mirror aluminum high reflectivity length and width can be customized

Alloy grades 1070 and 1085 belong to the industrially pure aluminum family and are commonly used as base materials for manufacturing high-reflectivity mirror-finished aluminum sheet and strip. They offer the following key advantages as mirror-finished aluminum substrates.

Extremely High Reflectivity
1xxx-series pure aluminum has the highest reflectivity of all aluminum materials. The 1xxx series has an extremely high aluminum content—1070: ≥99.70% and 1085: ≥99.85%—and very low levels of impurities. Impurities scatter light and reduce reflectivity. The higher the purity, the stronger the specular reflectivity of visible light. After precision rolling and polishing, the surface can achieve a reflectivity approaching 90% or higher.

Excellent Machinability
Extremely good ductility and softness. High-purity aluminum is inherently soft. This makes 1070/1085 mirror aluminum sheet/strip extremely easy to process through stamping, drawing, and bending, while remaining remarkably resistant to surface defects like cracks and orange peel. This is crucial for applications requiring complex shapes, such as reflectors, lamp cups, and decorative parts. It also maintains its shape and reflective properties well after forming.

Excellent Anodizing Performance

It produces a uniform, dense, and transparent anodic oxide film. The low impurities result in a highly pure oxide film, which, especially when dyed, offers a more uniform color and high light transmittance, minimizing the impact on the reflective properties of the final product. While reflectivity decreases slightly after anodizing, the film provides protection. This is crucial for functional or decorative mirror aluminum products requiring increased surface hardness, corrosion resistance, or dyeing.

Relatively Low Cost

Compared to other 5xxx, 6xxx, and 7xxx series aluminum alloys, which often contain expensive alloying elements, pure 1xxx series aluminum generally has lower raw material and processing costs. This makes 1070/1085 mirror aluminum an economical choice for high-volume, cost-sensitive applications.
