iPhone Pro models are unlikely to return to titanium in the near future due to local AI heat dissipation requirements, according to a known Weibo leaker.
The claim comes from the leaker known as “Fixed Focus Digital” and pushes back on an earlier report from “Instant Digital,” which suggested Apple was considering the use of liquid metal or an enhanced titanium alloy as a long-term replacement for aluminum iPhone frames. Fixed Focus Digital says the thermal properties of aluminum make it the only practical choice for now, given the processing requirements of AI features. The leaker adds that this is not an Apple-specific issue, noting that Android and Huawei HarmonyOS devices also prioritize aluminum for the same reason.
Instant Digital’s previous report claimed that Apple’s switch from titanium to aluminum for the iPhone 17 Pro was a compromise solution while continuing to develop longer-term alternatives. The leaker claimed that Apple is exploring both liquid metal and revised titanium alloys for future Pro models, with both materials apparently already reserved for the next foldable iPhone.
Apple abandoned titanium following complaints of overheating on the iPhone 15 Pro and iPhone 16 Pro models, although the iPhone Air continues to use it. Fixed Focus Digital’s assessment suggests that aluminum is more deeply embedded in Apple’s plans than Instant Digital’s framework suggests, at least for the foreseeable future. The iPhone 18 Pro is expected to retain the same aluminum unibody design as the iPhone 17 Pro models, meaning a hardware change is unlikely until 2027 at the earliest.
