Apple analyst Jeff Pu has revealed that the upcoming iPhone 17 Air model will have a titanium frame, unlike its Pro counterparts which will feature aluminum frames. The reason behind this choice is unclear, but it may be due to the need for added durability considering the device’s ultra-thin and lightweight design. This material change marks a notable departure from Apple’s previous use of titanium in their highest-end iPhone models since 2017.
