Samsung is apparently trying to pair titanium's ruggedness with Aluminum's better thermal performance, bringing the best of both metal frames to its future lineup of foldables.
Interestingly, Samsung's relatively simple approach to smartphone-geared metallurgy can serve as an effective counter to Apple's more complicated efforts with the so-called Liquidmetal.
The tipster Schrödinger has just penned an interesting post on his Telegram channel, detailing Samsung's latest smartphone-related metallurgy efforts.
According to the tipster, Samsung is apparently working on a hybrid, 'dual-phase' smartphone frame that "fuses an outer titanium shield with an inner Aero-grade aluminum core."
Schrödinger goes on to note:
"Think of it as "thermal zoning." The outer Titan skin maintains that rigid, jewelry-grade scratch resistance, while the high-conductivity aluminum interior acts as a giant heat sink to draw thermals away from the mainboard."
As per the post's prevailing hypothesis, Samsung's hybrid 'dual-phase' frame might be a response to the brouhaha surrounding Apple's Liquidmetal-related innovation, and is likely to debut on "a future Fold, Trifold and thin-slab premium tier," especially given the "staggering" cost of fusing these two disparate metals via nano molding.
For the benefit of those who might not be aware, Apple's Liquidmetal is basically the commercial branding of an amorphous metal alloy, which is cooled rapidly during the manufacturing stage to prevent atoms from arranging themselves in neat crystalline shapes. This leaves the atoms in a chaotic and disordered arrangement that resembles the atomic structure of glass. The resulting metal is around 1.5x harder than stainless steel and 2.5x stronger than standard titanium, while still able to flex under stress.
Of course, given the exorbitant costs involved, both Samsung and Apple are only expected to incorporate these innovations within their uber-premium offerings. For instance, Apple is widely expected to use a Liquidmetal hinge within the upcoming iPhone Ultra. Likewise, Samsung might well reserve its titanium-aluminum frame for a future TriFold iteration.
