The term "liquid metal" sounds like science fiction, but the material—officially known as an amorphous alloy or metallic glass—has been in Apple’s back pocket for over a decade. Unlike traditional metals with a crystalline atomic structure, Liquidmetal cools so rapidly that its atoms freeze into a random, glass-like arrangement. The result is a material that is incredibly strong, highly corrosion-resistant, and naturally elastic, making it perfect for components that endure constant mechanical stress without deforming .
For a foldable phone, the hinge is the single most vulnerable point of failure. A liquid metal hinge addresses this by resisting the microscopic wear that creates the dreaded screen crease, while also delivering a smoother, more consistent folding action over years of use .
Apple’s relationship with this technology dates back to August 5, 2010, when the company paid a one-time fee for a perpetual, worldwide, fully paid, exclusive license to use Liquidmetal Technologies' intellectual property in consumer electronics . For years, the only public evidence of this partnership was a humble SIM card ejector pin. The foldable iPhone hinge marks the first structural, large-scale use of the material in a product intended for tens of millions of users .
While Apple itself remains characteristically silent, a remarkably consistent picture has emerged from analyst notes, component suppliers, and leak aggregators :
The road to September has not been smooth. In May 2026, leaker Instant Digital reported that trial production of the device—often referred to internally as the iPhone Ultra—had stalled. The culprit: hinge assemblies that were failing Apple’s brutal durability tests, which simulate years of high-frequency opening and closing within days . The leaker stressed the issue "must be resolved with absolute perfection" before full production can resume.
Shortly after, DigiTimes reported that mass production had slipped by one to two months, from a planned June start to a July or August ramp-up . Despite this compressed schedule, Bloomberg’s Mark Gurman and other sources report that Apple has told suppliers the plan is still to unveil the device at its traditional September event alongside the iPhone 18 Pro and Pro Max. However, anyone hoping to grab one on day one should prepare for a likely limited initial supply that could stretch for weeks .
The exclusive supplier of this critical liquid metal is China’s Dongguan EonTec, a detail first reported by TF International Securities analyst Ming-Chi Kuo back in March 2025 . By late 2024, EonTec had already shipped over 10 million axial hinge components, signaling its ability to scale up fast. Production is expected to flow through Dongguan Yihao Metal Technology, a contract manufacturer in which EonTec holds a 60% stake .
On the other side of the relationship, U.S.-based Liquidmetal Technologies maintains cross-licensing agreements with EonTec and operates a 70%-owned joint venture in Hangzhou, China, to anchor the manufacturing chain. The entire operation has been quietly built around Apple’s exclusive IP rights and EonTec’s industrial capacity .
All of this information comes from the intricate web of Apple’s global supply chain—leakers, analysts, and component makers. Apple has not officially announced any foldable iPhone. While September 2026 is the consensus timeline backed by a wide range of respected sources, the hinge delays and tight production schedule make a slight slip into late 2026 at least plausible. Pricing, too, is an informed estimate based on component costs, not a published retail price.
Still, the shipment of functional prototypes to global carriers is the strongest signal we’ve ever seen. Apple’s foldable iPhone is real, it’s deep in the validation gauntlet, and it's closer to a store shelf than ever before.
