• 🪞
  Superior Reflectivity Depending on the grade and processing technique, its reflectivity ranges from 80% to over 95%. High-end products can even reach a near-mirror effect (≥92%), comparable to glass mirrors but with better impact resistance.
• ⚖️
  Lightweight & High Strength With a density of only about 2.7g/cm³ (one-third that of steel), it is easy to transport and install. Meanwhile, its tensile strength (110–300MPa, depending on the alloy) ensures durability in structural applications.
• 🛡️
  Excellent Corrosion Resistance The natural aluminum oxide film on its surface, combined with optional post-treatment (e.g., anodizing, coating), provides strong resistance to moisture, chemicals, and atmospheric erosion—suitable for both indoor and outdoor use.
• ✍️
  Good Formability It can be easily processed via cutting, bending, rolling, stamping, or welding without damaging the mirror surface, adapting to complex shapes required by different products.
• ♻️
  Eco-Friendly & Recyclable Aluminum is 100% recyclable with minimal loss of performance. The production process of mirror aluminum also emphasizes low energy consumption compared to other reflective materials (e.g., stainless steel).

The manufacturing of mirror aluminum coil/sheet involves strict, multi-step processing to ensure surface smoothness and reflectivity:

1. Base Material Selection High-purity aluminum coils/sheets (e.g., 1050, 1060, 1100 for general use; 3003 for enhanced corrosion resistance; 5052 for higher strength) are chosen as the raw material, as impurities would affect surface flatness.
2. Degreasing & Cleaning The base material is cleaned with alkaline or acidic solutions to remove oil, dust, and oxide layers, ensuring no contaminants interfere with subsequent polishing.
3. Precision Polishing This is the key step to achieve the mirror effect. Two main methods are used:
   • Mechanical Polishing: Abrasive belts (from coarse to ultra-fine grit) or polishing wheels are used to grind the surface repeatedly, gradually reducing roughness to Ra ≤0.02μm.
   • Chemical Polishing: The aluminum surface is treated with a mixed acid solution (e.g., phosphoric acid, nitric acid) to dissolve micro-irregularities, creating a smooth, reflective finish—often used for high-precision applications.
4. Surface Protection To maintain the mirror effect and enhance durability, protective treatments are applied:
   • Anodizing: A thick, hard oxide film (5–20μm) is formed on the surface via electrolysis, improving scratch resistance and allowing for color customization (e.g., silver, gold, black).
   • Coating: Polyester (PE) or fluorocarbon (PVDF) coatings are sprayed on the surface, providing UV resistance and color stability—ideal for outdoor applications like building facades.
   • Film Lamination: A thin PE protective film is attached to prevent scratches during transportation and installation.
5. Slitting & Cutting The polished aluminum coil is slit into coils of different widths or cut into sheets of specific sizes (e.g., 1220×2440mm) based on customer needs.

Different alloys are selected based on application requirements for strength, corrosion resistance, and formability:
