Apple's upcoming foldable iPhone will have a frame that's made from a mix of titanium and aluminum, analyst Jeff Pu said today in a note shared with investors.

Pu suggested that Apple will expand its use of titanium, with the material set to be used in both the 2026 iPhone Fold and iPhone Air models. This isn't the first time a mixed metal chassis has been rumored for the foldable iPhone, because Apple analyst Ming-Chi Kuo said earlier this year that Apple will use multiple materials.

While Pu says Apple is going to use titanium and aluminum, Kuo said that Apple will use titanium and stainless steel. He suggested that the foldable iPhone's hinge will be made from stainless steel and titanium, with the device's frame set to be made from titanium. Kuo also believes some hinge components will be made from Liquidmetal for further durability.

The foldable iPhone is rumored to be as thin as 4.5mm when opened up, which would make it even thinner than the iPhone Air. It would need the strength of a titanium frame to prevent bending issues. Apple gave the iPhone Air a titanium frame, and that proved to be a good decision because multiple bend tests show that the titanium Apple used for the iPhone Air is resistant to bending.

Kuo did not mention aluminum as a potential material for the foldable iPhone. Pu's wording isn't entirely clear on how Apple will use the two materials, but he's either suggesting that Apple plans to use a titanium and aluminum hybrid compound for the device's frame, or saying Apple will use titanium in some areas and aluminum in other areas.
Additionally, 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.

Small amounts of aluminum are often used in titanium alloys, and the two metals can be combined in higher proportions as well. Since titanium is heavier than aluminum, Apple might also be planning to use titanium for the stress bearing parts of the frame and aluminum elsewhere to cut weight.

Apple's foldable iPhone is expected to be part of the iPhone 18 lineup, launching in September 2026. Rumors suggest that the display will be around 5.5 inches in size when closed, unfolding to approximately 7.8 inches when opened up.

Solves a problem that doesn't exist, 6+ years after the competition launched their folding phones.
Friends I have that had LG and Samsung foldables got them at extreme discount, and said they would never buy another foldable phone (crease in the screen that forms, grit and dirt that gets on the screens grinds in your pocket, etc)

This just shows you how different people are. Every friend of mine who has bought a foldable says they would never go back to a slab phone. I'm included in this group of people. I wouldn't use a slab phone if you paid me. I don't know how people can surf the web, view photos, read Kindle books, check stock quotes, compose and read/reply to emails, watch videos, etc. anymore on slab phones now that foldables exist. I do realize foldables are not for everyone though.

I heard it's going to weigh more than 300g (10.5oz), and be described as featherweight ...
 
I really want the foldable, but I will probably wait for the second version (2027) since this will be such a new form factor and since there were so many improvements on Samsung's and Google's subsequent models over their first model. I definitely don't want to be the least bit disappointed with a (rumored) $2000 phone.

although these rumors just confirm what we have already been suspecting (after the launch of the iPhone Air), the iPhone Fold is sounding better and better.
if they can achieve a price point of somewhere around USD 1999 for base configuration, it will be a great phone.
probably could have around 48 hour battery life. with multiple cameras, etc. i hope they are able to overcome any problem that they might have with putting Face iD on the front screen (closed) and on the unfolded screen side as well.

I have seen the exact opposite from people with Samsung foldables. To each their own. This is a day one purchase for me.
