In a note to investors seen by AppleInsider, investment firm JP
Morgan Chase’s China office has reported to its clients that Apple
intends to introduce a titanium alloy to the iPhone for the first
time. Apple has already used titanium in some Apple Watch models,
for the physical Apple Card, and at times for the PowerBook.
Titanium’s toughness, though, is only achieved when it used as
part of a titanium alloy with other metals. Titanium is also prone
to smudges from fingerprints, and its finish can be unattractive.
Apple is therefore certain to be using an alloy, and it presumably
addresses these issues.
I hope this is true. Stainless steel is just too heavy; titanium would be a much nicer premium upgrade over aluminum. The titanium Apple Watch models are great, especially the Space Black model with a highly scratch-resistant DLC finish.
