Apple said to be using a liquid metal hinge for its rumoured foldable iPhone

Apple is said to be considering using liquid metal for the hinge of the rumoured foldable iPhone.

Analyst Ming-Chi Kuo shared that the hinge will be made of liquid metal using a die-casting process. Apple's decision to use liquid metal is attributed to its goal of "improving durability, enhancing screen flatness, and minimising crease marks in its foldable iPhone design". 

Kuo added that this would be Apple's first significant use of liquid metal for an essential mechanical component. The iPhone maker has used liquid metal for several years, but only in small components such as SIM ejector pins. 

Current foldable phones also use metal materials for their hinges. For example, the Google Pixel 9 Pro Fold has a hinge made of multi-alloy steel with an aerospace-grade high-quality aluminium alloy. The OPPO Find N5's Titanium Flexion Hinge has its cover and wing plates made from Grade 5 titanium alloy, while the load-bearing parts use OPPO-customised Ultra-High Strength Steel. The Samsung Galaxy Z Fold6's hinge is made of Enhanced Armour Aluminium. 

Apple's foldable iPhone is expected to adopt a book-style design with a 7.8-inch crease-free main display and a 5.5-inch cover display. Other rumoured specs include a Touch ID power button, a dual-camera module, and a chassis made of titanium alloy. It is believed to launch in late 2026 or 2027.
