The hinge of Apple's inaugural foldable iPhone Fold is ingeniously crafted from liquid metal. This material is a special kind of "amorphous" alloy, a field in which Apple has dedicated 15 years of research. In contrast to metallic crystalline materials, amorphous alloys boast exceptional processing capabilities and mechanical properties. Their atomic structure closely resembles that of a liquid, rendering them more "fluid" than traditional, static metallic materials. This characteristic also makes them easier to precisely shape during the manufacturing process.
