what part of the iphone 15 is titanium

The titanium on the iPhone 15 lineup is only on the Pro models, and it’s just the outer structural band around the edges, not the whole body.

Quick Scoop

• The standard iPhone 15 and 15 Plus do not use titanium; they have an aluminum frame with a glass back.

• The iPhone 15 Pro and 15 Pro Max use Grade 5 titanium on the outer band/frame you touch and see around the sides of the phone.

• Under that band, there is an internal aluminum frame ; the phone is not a solid titanium block.

• Teardown and materials testing show the titanium layer is a thin shell (about 1 mm thick) bonded to the aluminum structure, mainly for weight savings, strength, and premium feel.

So if you’re holding an iPhone 15 Pro or Pro Max, the titanium is the side rail/band and corner frame around the device, while the inside skeleton is aluminum and the back is glass.
