1. Domestic mirrored aluminum sheet and imported mirrored aluminum sheet
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 high-end products, then choose imported mirrors.
For low-end products, choose domestic ones.
At present, the domestic mirror surface characterize no protection treatment surface,
the mirror surface rate will change with time, and the price is low;
the imported product characterize stable reflectivity, divided into two grades:
86 ordinary mirror surface and 95 super mirror surface, and the price is more Slightly more expensive.
The best mirrors are from Germany and Italy.
Japanese mirrors are non-oxidized and are made of standard sheet materials with high loss.
However, its unique silk effect favored electronics housing manufacturers.
2. Test method
Simple test method: Imported mirror surface aluminum plate, after tearing off the protective film, touch the mirror surface with your fingers,
the sweat stains on your fingers will remain on the mirror surface, but after wiping with a dry cloth or paper towel,
the fingerprints will wipe clean without leaving behind Any traces.
The domestic mirror aluminum plate is different, the fingerprints left behind will become dirtier and dirtier, and the mirror effect cannot restore in the end.
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 proves to import an alumina plate, otherwise, it domestic ordinary polis plate.
Because the surface of the imported oxidized mirror aluminum plate itself has a layer of 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 during bending.
