it was already mention during the announcement . also titanium is not a good conductor, of cos it had to be bond with another conductive material internally , its the same thing with the nature of the materiel of titanium , while it has good tensile strength(dont really flex upon pressure ) , lighter , but the downside is titanium scuff and scratch easily and is not forgiving in terms of impact / shock absorption in comparison of SS . i am baffle with how easy to acquire information nowdays some people just do not take the time to educated themselves with a simple click of the internet, but relies on big title because everyone said so .

Goodness. In the Wonderlust presentation, the material was stated to be "the same alloy used on spacecraft". "Alloy" meaning "a substance composed of two or more metals or of a metal and a nonmetal" (Merriam-Webster Dictionary). If it's an alloy, of course its not 100% Titanium. Someone didn't pay attention in chemistry class.

Grade 5 Titanium does include 6% aluminum. But the frame itself is a composite sandwhich that is more aluminum than titanium. They did mention it on the presentation, but they sure didn’t give the impression that there is exactly 1mm of titanium and the shell is mostly aluminum ( as is the internal support structure).

They could have easily given a cross section on the presentation, but Apple just over plays everything at the moment.

This is why, folders aka pocket knife are mostly made of titanium due to the tensile strength as its a hard use tool. But the finish is mostly stonewash to hard the scratches as it has low hardness in comparison

It boggles my mind how some of folks like the OP, could even think it was fully made of Titanium. Do they not realize how expensive the phone would be if made completely of Titanium? And do they not listen to the keynote where they clearly explain the composition of the materials used?

lol not sure whether you were quite active in chemistry class either. An alloy is a homogeneous chemically combined mixture. The titanium frame is an alloy by itself(which is what Apple meant on stage). But the whole chassis with the aluminium and titanium components isn’t considered an alloy. Just welding aluminum and titanium or any two metals together physically doesn’t making it an alloy lol

Didn’t Apple disclose this in a major press release to the public? Why yes. Yes they did.


A Stunning, Lightweight, and Durable Design​

Available in 6.1-inch and 6.7-inch display sizes,2 iPhone 15 Pro and iPhone 15 Pro Max feature a strong and lightweight titanium design — a first for iPhone. This premium alloy — the same used in spacecraft — has one of the highest strength-to-weight ratios of any metal, making this Apple’s lightest Pro lineup ever. Both models feature a new refined brush texture, contoured edges, and the thinnest borders on iPhone. The Pro lineup is built to last, combining the strength of titanium with the toughest back glass in a smartphone and the industry-leading Ceramic Shield on the front. Using an industry-first thermo-mechanical process, the titanium bands encase a new substructure made from 100 percent recycled aluminum, bonding these two metals with incredible strength through solid-state diffusion. The aluminum frame helps with thermal dissipation and allows the back glass to be easily replaced. This new design highlights the Super Retina XDR display with Always-On and ProMotion technologies for an exceptional viewing experience.
