Xiaomi’s latest teaser for its upcoming flagship 5G phone hints that the phone is made from new premium materials. While the poster doesn’t exactly say, we know it is the Mi MIX Alpha that will be made from these new materials.

The poster shows three materials – Ti (Titanium), SiO2 (Silica), and Al2O3 (Alumina). All three materials are actually familiar when it comes to phones. Titanium is used for making the frame of phones. For example, the Essential PH-1 has a titanium frame. Silica, on the other hand, is a primary ingredient used in the traditional glass industry, and Alumina is used in making hard glass. We believe the phone will use all three materials.

Mi MIX New Materials

The caption for the poster says Xiaomi has always been exploring new materials and designs for its phones. It mentions examples like the Mi 4 which has a stainless steel frame, the Mi Note which has a 3D curved glass back, the Mi 5 with its ceramic back, and the Mi MIX 2 with its ceramic unibody. It then asks what other materials should be considered for the 5G era.

The Mi MIX Alpha and Mi 9 Pro 5G will be unveiled on September 24 alongside the Mi TV Pro.
