How To Distinguish The Type Of Mirror Aluminum Plate
Dec 15, 2020

There are many types of mirror reflective aluminum plates, from low to high grades, including filmed mirror aluminum, domestic polished mirror aluminum, imported polished mirror aluminum, imported oxidized mirror aluminum, and super mirror aluminum.

Choose the reflector that suits you according to the characteristics and positioning of your product. If you want to make a high-quality product, then choose the imported mirror. If it is low, choose the domestic one. The characteristic of domestic mirror surface is that the surface is not protected, the mirror surface rate will change with the change of time, and the price is cheap; the imported product is characterized by the non-chaotic reflectance, divided into two grades of 86% ordinary mirror surface and 95% super mirror surface. Slightly more expensive.

The mirror surface of Japan is from Germany and Italy. The mirror surface of Japan is not oxidized, and it is a standard sheet material with high loss, but its unique silk effect is favored by electronic product shell manufacturers.

Simple test method: the entrance mirror aluminum plate, after tearing off the protective film, touch the mirror surface with your fingers, the sweat stains on the fingers will remain on the mirror surface, but after wiping with a dry cloth or paper towel, the fingerprints will be wiped clean without leaving behind Any traces.

The domestic mirror aluminum plate is different, the fingerprints left behind will become more and more dirty, and the mirror effect cannot be restored.

There is another test method:

Put a small aluminum plate near your ear and bend it quickly. If you can hear a slight tearing sound, it is confirmed to be the imported alumina plate, otherwise it is a domestic ordinary polished plate. Because the surface of the oxidized mirror aluminum plate at the entrance will have an oxide film similar to corundum, because the aluminum material itself has a different structure from the oxide film, the oxide film will burst and make a slight tearing sound when it is bent.
