Analyst Jeff Pu of GF Securities Hong Kong claims that Apple’s upcoming foldable iPhone will have a chassis made from a mix of titanium and aluminum. In a note shared with investors, Pu mentioned that both the iPhone Air and the foldable iPhone will use titanium in their frames, but it’s unclear how the two materials will be combined.
Pu stated, “The metal frame will turn favorable on increasing usage of titanium, which will likely be adopted by iPhone 18 Fold (titanium + aluminum) and iPhone 18 Air.”
There have been rumors of a mixed-metal chassis for Apple’s foldable handset before. Analyst Ming-Chi Kuo predicted that Apple would use multiple alloys for the device, with a mix of titanium and stainless steel for the hinge and titanium for the frame. He also mentioned the use of Liquidmetal for some hinge components for added durability.
Apple’s first foldable iPhone is rumored to be extremely thin at just 4.5 mm when open, thinner than the recently released iPhone Air. The device is said to have a display size of approximately 5.5 inches when closed, expanding to around 7.8 inches when opened.
Samsung is expected to be the vendor for foldable iPhone displays, with preparations for mass production already underway. Apple is likely to debut its foldable iPhone as part of the 2026 iPhone 18 lineup, potentially boosting sales in the foldable phone market.
Overall, Apple’s entry into the foldable market with high-end materials like titanium could reshape the landscape of flexible smartphones.
