Apple’s upcoming foldable iPhone is set to include a groundbreaking liquid metal hinge, with prototype units now being tested by carriers globally. Development and production are advancing swiftly, with recent reports highlighting the use of vapor chamber cooling in the device. The liquid metal hinge is a notable advancement, addressing previous concerns about production challenges. This amorphous metal alloy offers a higher strength-to-weight ratio and enhanced durability compared to traditional metals, making it suitable for the foldable iPhone’s demanding use.
Apple’s association with liquid metal dates back to 2010, when it secured exclusive rights to use the material in consumer electronics. Although initially applied to minor components, the company has been exploring its potential for larger structural uses, such as hinges. Reports suggest Dongguan EonTec will supply the liquid metal for the iPhone’s hinge, although there were earlier considerations of alternative materials like 3D-printed titanium alloy.
The arrival of prototypes at global carriers signifies a key step toward the device’s commercial launch, with mass production anticipated to begin soon. The foldable iPhone is expected to debut in September alongside other models, featuring a 7.8-inch inner display, a 5.5-inch cover display, the A20 chip, and other advanced specifications, with a starting price around $2,000.
