Recent reports suggest that the chassis of the iPhone 17 Pro will be made from aluminum instead of titanium, indicating that Apple might be moving away from a key feature it highlighted for its Pro line just last year.
However, a leaker known for reliable information has challenged this claim, asserting that Apple will indeed continue to utilize titanium for its premium models next year—though this discrepancy could stem from unclear wording.
The Introduction of Titanium by Apple in 2023
Historically, Apple has differentiated its standard and Pro iPhones by their chassis materials, using aluminum for standard models and stainless steel for Pro versions.
However, last year marked a change, with the iPhone 15 Pro and Pro Max featuring titanium in place of steel. Apple appeared to promote this transition extensively, emphasizing it right at the start of their announcement.
Apple today unveiled the iPhone 15 Pro and iPhone 15 Pro Max, featuring aerospace-grade titanium that is both strong and lightweight, making these Apple’s lightest Pro models to date.
The company added:
“This is the most professional lineup we have ever created, boasting a state-of-the-art titanium design.”
“The iPhone 15 Pro and iPhone 15 Pro Max present a robust and lightweight titanium structure—an industry first for the iPhone. This premium alloy, which is also employed in spacecraft, offers one of the highest strength-to-weight ratios of any metal, resulting in Apple’s lightest Pro lineup ever.”
Next Year: Titanium or Aluminum?
Nonetheless, The Information reported last week that next year’s Pro models would switch back to aluminum from titanium.
“In addition to the iPhone 17 Air, other iPhone models are set to undergo major design changes next year, including a transition to aluminum frames from stainless steel and titanium,” said one source.
Leaker Instant Digital has pushed back against this notion.
“Of course, the 17 Pro will still be made of titanium. Why would you switch to aluminum? It’s hard to fathom. Over the years, Apple has made a point of emphasizing the premium materials used for frame construction in the Pro series, from ‘surgical-grade stainless steel’ to ‘titanium’. How would changing to aluminum fit into that narrative?”
Thoughts from DMN
First, it’s important to note that there may be some unclear terminology at play. The Information mentioned that the “frame” would be aluminum, but as Apple defines it, the “band” around the display is already titanium. The internal metal framework is referred to as the “frame” or “substructure.” Here’s a highlight from Apple’s presentation:
“Our innovative thermo-mechanical process allows the titanium BANDS to encase a new SUBSTRUCTURE made from 100% recycled aluminum, bonding these two materials with exceptional strength through solid-state diffusion. The aluminum FRAME enhances thermal dissipation and simplifies back glass replacement.”
Second, while Instant Digital’s insights are generally trustworthy, it’s important to point out that this response is primarily conjectural rather than sourced from supply chain information.
What Do You Think?
Setting aside the vocabulary debate, if the outer band does transition from titanium to aluminum, would this be a significant issue for you?
