How to achieve the metallic silver luster
The luster effect of Mercury Silver UMIDIGI S2 Pro was made possible by adopting a metallic refining process called anodic oxidation treatment, or simply known as anodizing. By anodizing the aluminum alloy surface, which generates a hard layer of oxide film that colors and a layer of protective film can be generated on the aluminum surface of the phone. Apple’s iPhone 7 applied the same technique, but a more complicated process was added to make the silver UMIDIGI S2 Pro, which is called Electrophoresis Method that makes the silver look even glossier.
