The iPhone 11 Pro rear cover may have been made of metallic glass

Apple's new iPhone 11 series is designed with double-sided glass. Among them, 11 Pro boasts the hardest glass in smartphones. In addition, if you look at the back of it, you will find some wonderful differences. The official website advertises the back cover of the iPhone 11 Pro as "precision polishing, made of a whole piece of glass, double ionic exchange". Change the process to strengthen the treatment. In addition to the lens system, the protruding part of the surface is polished and bright, while the other areas of the rear cover are ground, which is more like a metallic texture than glass.


A new Apple patent released by the U.S. Patent Office may reveal the secret behind the patent filed in the first quarter of 2019 called "thermoplastic molding of metallic glass texture made from glass molds."

Metallic glass is one of the hardest glasses, and Apple is likely to use the approach outlined in the latest patent application to give the iPhone 11 Pro back texture. In fact, the inventors of the patent were also responsible for making iPhone X and XR metal alloys, so the new metallic glass is consistent with the continuity of their work.

Apple's invention shows how to reproduce fine texture in a silicate glass mold by placing metallic glass in a glass mold with fine surface texture, heating the glass mold to a glass transition temperature higher than that of metallic glass, and applying pressure to the silicate glass mold. Cooling the glass mould to form metal glass products, copying the fine surface texture of the glass mould part and a series of steps.

Anti-Glareglass technology is used for surface treatment of glass. Many products have used AG technology to make abrasive feeling before, but the most important hint of the new patent is to combine metal glass with chemical etching grinding, which is more complex and expensive. The possibility of adding metal glass to the iPhone 11 Pro is very high, and I believe this new material will continue to be used in other new products of Apple in the future.
