Apple moved away from titanium with the iPhone 17 Pro and returned to an aluminum-based design, but a new leak suggests the company has not given up on the material yet. According to a new claim from leaker Instant Digital, Apple is actively researching an “improved version” of titanium for future iPhone models as it seeks a better balance among durability, weight, and heat management.
Apple first introduced titanium with the iPhone 15 Pro lineup in 2023, positioning it as a premium feature for its high-end devices. However, reports about the iPhone 17 Pro suggested that aluminum would replace titanium due to thermal concerns and manufacturing trade-offs.
Apple reportedly wants titanium back
In a new Weibo post,
“I’ve previously mentioned that Apple is proud to use titanium in its phones, and the use of aluminum in the 17 Pro was a forced compromise. This is true, so Apple hasn’t abandoned titanium and seems to be researching an improved version.”
Instant Digital also claimed Apple wants to fix the “poor thermal conductivity” of titanium alloy while also making the material lighter without increasing overall size or thickness.
The leaker added that Apple could return to titanium once the “new formula is mature,” which suggests the company is still experimenting with materials behind the scenes instead of fully committing to aluminum long term.
Heat management remains a key challenge
The report also mentioned liquid metal as another possibility for future iPhones, especially for the rumored iPhone Ultra hinge, though mass production remains “extremely difficult.”
Apple still reportedly uses titanium in thinner products like the iPhone Air because of its strength and durability benefits. Future vapor chamber cooling systems could also help Apple solve heat dissipation problems and make titanium practical again for future Pro models.
