As explained here, metallic glass stands apart from traditional metals because it lacks a regular crystalline atomic structure. Instead, its atoms are arranged in a disordered way, making it significantly more resistant to bending, deformation, and even denting. This unique atomic structure, created through rapid cooling processes, makes metallic glass roughly 2.5 times harder than titanium alloys. A bonus: the material’s smooth, glossy finish offers an appearance comparable to high-end stainless steel, aligning perfectly with Apple’s sophisticated design language.
But metallic glass isn’t just about good looks. The material’s inherent resistance to corrosion also ensures the hinge mechanism remains reliable under various environmental conditions. Given that the hinge will endure constant stress from repeated folding and unfolding, these properties could effectively reduce common problems found in today’s foldable smartphones, such as screen creases and deformation.
Previous leaks indicate that the iPhone Fold will feature:
• A 7.8-inch unfolded main display and a 5.5-inch external cover screen
• A book-style design reminiscent of Samsung’s Galaxy Z Fold
• Two rear cameras, a single front-facing camera, and Touch ID integrated into the power button
• Remarkably thin dimensions, measuring just 4.5mm thick when unfolded and 9mm–9.5mm thick when closed
• A premium price point around $2,000
Considering Apple’s reputation for precision engineering, the adoption of metallic glass could set new standards for foldable device durability. It remains to be seen if this technology will truly enhance user experience as promised, but Apple’s proven track record when it comes to its iPhone hardware gives us good reason to keep expectations high.
