Key Differences
Polished aluminum mirror sheets and mirror finish anodized aluminum sheets differ in their production process, performance, and cost:
- Polished Aluminum Mirror Sheets: These are treated with simple surface polishing. They are less durable and more prone to damage.
- Mirror Finish Anodized Aluminum Sheets: These undergo an anodization process, which enhances durability, scratch resistance, and overall quality.
Imported products are typically anodized, while domestic products often use polishing. This difference in treatment results in significant variations in performance and price.
How to Distinguish Between the Two
Here are three simple methods to identify anodized mirror aluminum sheets and polished aluminum mirror sheets:
- Protective Film Test
- Remove the protective film.
- Touch the mirror surface and check for perspiration marks.
- Clean the surface with paper.
- If no marks remain, the sheet has undergone anodization.
- If fingerprints or dirt remain, it is a polished aluminum sheet.
- Sound Test
- Bend the aluminum near your ear.
- A slight cracking sound indicates anodization.
- No sound suggests the sheet is polished.
- Bend the aluminum near your ear.
- Bending Test
- Bend the sheet to a 90-degree angle.
- High-quality anodized sheets may show slight bleaching when the anodized film breaks.
- Poor-quality sheets or polished sheets will not show this effect.
- Bend the sheet to a 90-degree angle.
Tips for Selection
When choosing between these products:
- Inspect carefully to avoid low-quality materials.
- Be cautious of sellers offering inferior products disguised as higher-quality options.
- Opt for anodized sheets when durability and long-term performance are priorities.
