Rumored return to titanium after the aluminum iPhone 17 Pro doesn't make sense

A new leak claims Apple may bring titanium back to future Pro iPhones after moving the iPhone 17 Pro to aluminum, a reversal that could reintroduce many of the material's old tradeoffs. Render of an iPhone 18 Pro A May 17 Weibo post from leaker "Instant Digital" claimed Apple is researching improved titanium alloys for future iPhones rather than abandoning the material entirely. The post also claimed Apple is still exploring liquid metal and glass for future premium iPhone designs.
