A Potential Breakthrough for Folding Technology
Reports originating from Weibo suggest that Apple is exploring the integration of liquid metal into the design of the highly anticipated iPhone Ultra, which is expected to be a foldable device. The primary application for this material is speculated to be the phone's hinge mechanism. Unlike standard industrial alloys, liquid metal—technically known as an amorphous alloy—possesses a disorganized atomic structure, granting it superior flexibility and the ability to be molded into intricate shapes.
Understanding the Material: Beyond Science Fiction
It is important to clarify that this material is not a shape-shifting substance akin to the T-1000 from the Terminator series. Instead, it is a specialized metal glass that remains solid at room temperature. Industry observers have tracked Apple’s interest in this substance for over 15 years, with various rumors surfacing as early as 2010. While the company previously utilized the material to create a simple SIM ejection tool for the iPad, it has yet to incorporate it into a major hardware component.
The Quest for a Perfect Hinge
The engineering challenge with folding smartphones lies in two critical areas: the durability of the mechanical hinge and the resilience of the display itself. Industry experts suggest that a stronger, lighter hinge could significantly reduce common issues like screen delamination. As noted by the source, there is a clear strategic advantage to this approach:
“The aim would be to make the hinge lighter and stronger, while being able to form the complex shapes needed and to ensure durability.”
Competitive Landscape and Future Outlook
Apple is not the first company to explore these manufacturing techniques. Competitors, such as Oppo, have already implemented advanced methods, including 3D scanning and liquid printing, to develop hinge designs that minimize the visible crease on folding screens. By adopting similar principles with amorphous alloys, Apple could potentially address the long-standing durability concerns associated with foldable displays. If the current rumors hold true, the industry may see the first substantial application of this technology when the iPhone Ultra is potentially unveiled in September 2026.
