Apple is reportedly considering using titanium and Liquid Metal for its upcoming foldable iPhone, the iPhone Fold. This decision comes with the challenge of balancing durability, weight, and production cost, as the iPhone Fold's hinge and chassis will be under significant pressure from daily folding and unfolding. The choice of materials is crucial, especially for a groundbreaking product like the iPhone Fold.
The use of Liquid Metal in the hinge is a strong possibility. This amorphous metal alloy boasts an impressive strength-to-weight ratio, wear resistance, and the ability to maintain its form even after enduring hundreds of thousands of stress cycles. Apple has been researching Liquid Metal for over a decade, but its application in the iPhone Fold's hinge would represent a significant advancement, considering the complexity of a foldable hinge compared to a thin metal pin.
On the other hand, the use of titanium for the entire frame is more controversial. Titanium has proven its worth in recent iPhone Pro models, offering a premium feel, excellent durability, and high corrosion resistance. However, reports suggest that Apple might opt for a hybrid solution or even rely solely on aluminum for the chassis due to the high cost of titanium and the manufacturing complexities of foldable designs. The company is also testing a new titanium alloy that is stronger and lighter than previous versions, which could be a game-changer for foldables.
The iPhone Fold is rumored to launch in late 2026 or early 2027, and Apple is likely in the final stages of material selection and mass production preparation. This timing allows for potential last-minute design changes to ensure a superior product. As the tech world eagerly awaits the iPhone Fold, the choice of materials will be a pivotal factor in shaping Apple's long-term strategy in the premium smartphone market.
