Apple's highly anticipated foldable iPhone will incorporate an innovative metallic glass hinge system, according to recent industry reports. This advanced material choice aims to address common durability concerns in foldable devices.
The metallic glass, also known as amorphous metal, features a unique atomic structure that sets it apart from traditional metals. Unlike conventional materials with crystalline patterns, this specialized alloy has a disordered atomic arrangement that makes it exceptionally resistant to bending and deformation. Testing shows it performs 2.5 times harder than titanium alloy while maintaining an attractive stainless steel-like finish.
This material selection appears strategically chosen to tackle persistent issues in current foldable phones, including screen creasing and hinge wear. The metallic glass's natural resistance to deformation could help maintain a flatter display surface over extended use. Its high corrosion resistance also promises enhanced longevity under various environmental conditions.
While Apple has previously used metallic glass in smaller components like SIM ejector pins, the iPhone Fold represents the company's first major implementation in a critical mechanical element. Dongguan EonTec will reportedly serve as the exclusive supplier for this specialized alloy.
The device is expected to feature a 7.8-inch main display when unfolded and a 5.5-inch cover screen, adopting a book-style design. Additional reported specifications include dual rear cameras, a front-facing camera, and Touch ID integrated into the power button. The device may achieve remarkable thinness - just 4.5mm when unfolded and approximately 9mm when closed.
Industry analysts project the iPhone Fold will launch next year with an approximate price point of $2,000, marking Apple's entry into the growing foldable device market.
