Alleged iPhone 17 Pro Chassis Offers First Look at All-Aluminum Body

An alleged iPhone 17 Pro production leak may provide a first look at the device's milled all-aluminum chassis, which this year includes the camera bump – in contrast to last year's iPhone 16 Pro model that features a glass camera module attached to an all-glass back panel.

Originally shared by leaker Majin Bu, the image below could be of a moulding, but it still lines up with rumors that Apple has done away with the previous models' glass sandwich and titanium frame in favor of a more encapsulating aluminum chassis that has a rear cutout to house a glass section around the Apple logo for wireless charging.

The iPhone 17 Pro models adopt an oversized rectangular camera module that spans the width of the case. Reports suggest it will be the same color as the iPhone itself, rather than being part of a two-tone design.

The iPhone 17 Pro models will be the first high-end iPhones with aluminum frames since Apple split the lineup into Pro and non-Pro tiers. In recent years, aluminum has been reserved for lower-end models like the iPhone SE and iPhone 16. High-end models used stainless steel until the iPhone 15 Pro, which switched to titanium – a change Apple touted as a major upgrade.

Aluminum is roughly 40% lighter than titanium at similar volumes, so we could see the iPhone 17 Pro models carrying less weight. Aluminum is also a far better thermal conductor than titanium, so heat generated by the A19 Pro chip and battery may dissipate faster. Apple is also rumored to be using a new internal design that incorporates a vapor chamber heatsink to improve thermal performance.

While titanium generally offers a denser, more premium feel with subtle reflectivity, Apple's use of aluminum should allow for richer color options. This year, Black, White, and Gray are said to be accompanied by new Dark Blue and Orange colors.

We'll know the official look soon – Apple is expected to unveil the iPhone 17 lineup next month, with September 9 rumored as a potential iPhone event date. If that timing is accurate, then the most likely date for Apple to announce the event is Tuesday, August 26, since the company typically provides two weeks' notice.

Why is this? (MacRumors – a little more detail would have been interesting/useful here).

What properties does aluminium have that allows for richer colours, that titanium doesn't have?
Aluminum and titanium respond differently to the anodization process. Titanium is less of an electrical conductor than aluminum so it doesn't anodize as easily.

Second is that the oxidation layers created by the anodization process behave differently in aluminum versus titanium. The aluminum oxide layer readily bonds to dyes so it can be used for a wide variety of colors (hence the bright options for the base model iPhones). The oxide layer formed on titanium does not readily accept dyes, but the thickness of the oxide layer refracts light in different ways and can be used to create different colors based on the voltage used. Most of these colors will be relatively muted (think of the gold and blue options of the 16 Pro and 15 Pro).

Below is an example of the colors that could be achieved on titanium depending on the voltage used during anodization. (Note the flash likely makes the colors look brighter)

At this point, I'm almost sure the iPhone 15 Pro will be always remembered as a modern-day equivalent of PowerBook G4 Titanium. Proud to own one.

The iPhone 23 will be made of cardboard because it’s roughly 40% lighter than aluminum.

I don’t really care that it’ll be aluminum. I’ll appreciate the thermal benefits and weight reduction. That camera bump though… baby got BACK.

And the price bump is because of Taco. Aim your ire there.

I don’t know why everyone wants a lighter phone. It’s a phone. We’re debating something that weighs half a pound at the absolute most. What are you, a mouse?
Every time. EVERY TIME users comment on wanting a lighter PORTABLE DEVICE we get that one gym bro who doesn’t understand ergonomics and thinks a comment like this adds anything to the discussion.

Thankfully Apple understands (even if you don’t) that every gram can make a difference in usability for a device that is meant to be held in one hand.
