Xiaomi Mi 14 Ultra Titanium Special Edition Technology Revealed: The Processing Is Extremely Cumbersome

On March 12, Xiaomi Mi 14 Ultra Titanium Special Edition was officially launched. Xiaomi Mobile officially issued a statement saying that the machine has made great progress compared to the Xiaomi Mi 14 Pro Titanium Special Edition - its yield strength has been increased to about three times, and the strength of the entire machine has also been greatly improved.

1. Xiaomi Mi 14 Ultra adopts a unique mid-frame design. The metal frame extends from both sides to the back cover of the fuselage, which not only enhances the visual beauty, but also optimizes the tactile feel of the back connection and improves the strength of the entire machine.

2. As the "metal of the future", titanium is known for its excellent strength-to-weight ratio, allowing it to create lightweight and strong metal parts. In addition, it has excellent corrosion resistance and biocompatibility and is an advanced skin-friendly material.

   

   1. Xiaomi 14 Pro Titanium Special Edition uses TA-2 titanium, which has a high titanium content and can be regarded as "pure titanium". It has good ductility, toughness and is easy to process.
3. Xiaomi 14 Ultra uses stronger and stronger TC-4 titanium alloy with a yield strength of up to 900MPa. To overcome the difficulty of molding, Xiaomi uses the MIM metal injection molding process.

4. MIM process steps:

   • Heat the titanium metal profile, melt it into liquid, and spray it into metal powder.
   • Fuse titanium metal powder and adhesive particles for injection molding.
   • Sinter at high temperature, remove the adhesive, and apply high pressure to cast into the final shape.
5. MIM process is complex, but it can be processed near-net, reducing titanium metal waste. Metal parts made of MIM are internally isotropic, have no internal stress, and are more reliable in strength. After CNC machining and surface treatment, the middle frame of the Xiaomi Mi 14 Ultra Titanium Special Edition is formed.
