The iPhone models that use a titanium frame are the iPhone 15 Pro and iPhone 15 Pro Max.

Mini rundown

  • Apple first introduced a titanium frame with the iPhone 15 Pro series in 2023, replacing the polished stainless steel used on earlier Pro models.
  • The titanium frame helped make the 15 Pro and 15 Pro Max noticeably lighter while keeping similar or better rigidity and durability.
  • Later Pro generations briefly continued using titanium before Apple started shifting some higher‑end models back toward aluminum, and reserving titanium for select models (like the rumored “iPhone 17 Air”).

In forum discussions, many users say they prefer the lighter feel of titanium but still debate its scratch resistance and color wear compared to stainless steel.

Why people care about “which iPhone is titanium”

  • Trend factor : Since 2023, “titanium” has been used heavily in marketing and tech reviews, so it often shows up as a headline spec and trending forum topic.

Bottom line: if you’re asking “which iPhone is titanium” and looking at currently well‑known models, you’re mainly talking about the iPhone 15 Pro and iPhone 15 Pro Max , which kicked off the titanium trend in Apple’s lineup.
