How to Distinguish the Quality of Mirror Aluminum Plate?

We can see the Mirror Aluminum application everywhere in life such as lighting grille lamp, reflector of solar energy, etc. To Mirror Aluminum producers and users, almost people know the three common types of mirror aluminum plate- Laminate Mirror Aluminum, Polished Mirror Aluminum and Anodized mirror aluminum plate. But do you know how to distinguish the quality of them? Literally, Laminate Mirror Aluminum is to stick a layer of high reflective vacuum zincification compound material by using alloy 1060/3003. Polished mirror Aluminum is polish the surface to mirror effect. Anodized Mirror Aluminum is the highest quality mirror type with 1-4 micron oxidation film, the alloy is imported 1085. But do you know how to distinguish the Anodized and laminate mirror aluminum plate?

Actually, there are several ways to see the difference between them. Now I tell you three easy ways. Firstly, we can take a mirror aluminum sample and tear off the surface protective film, then touch the mirror surface with finger. By soft paper wiping the perspiration on the mirror surface, it is oxide mirror aluminum if the surface no finger print trace. Oppositely, it is polished or lower quality mirror aluminum plate if the mirror surface leaves fingerprint trace and more dirty after paler cleaning.

Second way to distinguish the quality is voice listening. Taking a sample to slightly fold in ear to listen the concrete voice, we can make sure it is anodized mirror aluminum by hearing a slightly cracking noise. Otherwise, it is polished mirror aluminum without hearing any voice.

The third way is to 90 degree T-bend the sample, there will be slight white phenomenon for high quality mirror aluminum plate. The oxidation film will be white if the oxide film cracking. However, there will be no white on the surface for the low quality mirror aluminum.

These three easy ways can help you know well to distinguish the quality of mirror aluminum plate. Manufacturing anodized aluminum plate, Changzhou Dingang is the specialist. Please contact us if you need this product.
