Apple Taps 1.5x-Harder Liquidmetal Hinge as iPhone Ultra Heatsink

Apple’s foldable iPhone Ultra is now tipped to use its hinge as part of the phone’s thermal system, channeling heat away through a designed pathway rather than relying only on internal cooling.
Liquidmetal is expected to form that hinge, giving Apple a material said to be 1.5x harder than stainless steel and 2.5x stronger than standard titanium while still flexing under stress.
The hinge-based approach would complement a previously reported vapor-chamber cooling system, suggesting Apple is building an unusually elaborate heat-management setup for the foldable.
One key uncertainty remains durability at the enclosure level: it is still unclear whether the device will achieve IP68 dust and water resistance.
Separate leaks also suggest the iPhone Ultra could outweigh Samsung’s Galaxy Z Fold 8, underscoring possible trade-offs from Apple’s more engineered design.
