It is lightweight, highly durable and corrosion resistant
Unlike the titanium-aluminum alloy in the iPhone 15 Pro, Xiaomi decided to use titanium TA-2 with a purity of up to 99%. The production process of such a smartphone is more complex, and its cost is higher.
Xiaomi explained why it chose titanium instead of the more common stainless steel or other materials. A Xiaomi representative said that because titanium has advantages that other materials cannot match due to its unique physical and chemical properties, it is widely used in aerospace, medical, high-end sports equipment and other fields. It is lightweight, highly durable and corrosion resistant.
Engineers have simulated that if the Xiaomi 14 Pro uses a stainless steel middle frame, the smartphone will be heavier. Even if you use stainless steel and aluminum alloy weight-saving solutions, the smartphone will still be 8.34 g heavier compared to the titanium variant.
How the titanium Xiaomi 14 Pro protects itself from damage.
In addition, titanium metal also has special “hardening” properties, that is, the curved part will become harder, making the corners of Xiaomi 14 Pro stronger after bending and molding.
The material becomes stronger when deformed: this means that at the moment of falling and impact, its hardness immediately increases, which should protect the smartphone from damage.
Xiaomi also applied a ceramic PVD coating with a thickness of about 2 microns to the surface of the titanium TA-2, which can significantly improve the wear resistance and corrosion resistance of the phone, as well as make the surface more beautiful.
