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.

• 1xxx-series pure aluminum has the highest reflectivity of all aluminum materials
• 1070: ≥99.70% and 1085: ≥99.85% aluminum content with very low impurities
• After precision rolling and polishing, surface can achieve reflectivity approaching 90% or higher

• Extremely good ductility and softness
• Easy to process through stamping, drawing, and bending
• Resistant to surface defects like cracks and orange peel
• Maintains shape and reflective properties well after forming

• Produces uniform, dense, and transparent anodic oxide film
• Low impurities result in highly pure oxide film
• More uniform color when dyed with high light transmittance
• Film provides protection while minimizing impact on reflective properties

• Lower raw material and processing costs compared to other aluminum alloys
• Economical choice for high-volume, cost-sensitive applications
