Regarding the body material, Wayne Ma reported that the iPhone 17 Pro and Max will introduce aluminum frames for the first time, a claim confirmed by MacRumors. Apple has decided to abandon titanium alloy in favor of aluminum alloy for the new models, with one key consideration being environmental protection, as aluminum alloy typically has a lower carbon footprint than titanium alloy. Additionally, Jeff Pu revealed that the iPhone 17 Air will feature a titanium alloy frame. For the back panel material, Wayne Ma further noted that the iPhone 17 Pro and Max will adopt a new design, featuring a half-aluminum, half-glass structure, with the upper half made of aluminum and the lower half continuing to use glass.
