- 2017-03-15 09:51 -
The types of aluminum mirror sheets are many, from low to high grade, including film mirror aluminum, domestic polished aluminum mirror, imported polished aluminum mirror, imported anodized aluminum mirror and super aluminum mirror.
According to the characteristics of your products and positioning to choose your own reflector. If you want to do the quality of high-end products, then choose imported mirror. If you want to do the quality of low-end products, then choose the domestic mirror. At present, the characteristic of domestic mirror is that the surface is not protected, and the mirror rate will change with time and the price is low. Imported products are characterized by stable reflectivity, divided into 86% ordinary mirror and 95% super mirror, the price should be a little expensive.
The best mirror aluminum sheet manufacturer in China should be Mingtai aluminum. The best mirror is Germany and Italy at abroad. Japan's mirror is not oxidized, and is the standard specification sheet material, high loss, but its unique effect of silk has been favored by the electronic product shell manufacturers.

Imported mirror aluminum, after tearing protective film, if your fingers touch the mirror, the fingers sweat will stay in the mirror above, but with a dry cloth or paper towel to wipe after the fingerprint is wiped clean, leaving no trace.
Domestic mirror aluminum sheet is different, leaving the fingers will rub the more dirty, and finally can not restore the mirror effect
2.    Mirror aluminum test method two:
Will be a small aluminum sheet in the ear of the fast bending, if you can hear a slight tear sound, it is proved to be imported aluminum oxide, or vice versa, the domestic ordinary polishing sheet.
