Back in April, we first heard rumors about Apple planning to use 7000 ****** aluminum alloys (http://www.macrumors.com/2015/04/16/iphone-6s-7000-******-aluminum/) for the upcoming "iPhone 6s," taking advantage of some of the expertise gained in using the material for the Apple Watch Sport to make for a stronger iPhone body compared to the 6000 ****** aluminum used on the iPhone 6 and 6 Plus. That device received significant "Bendgate" attention after some early users found the device bending slightly (http://www.macrumors.com/2014/09/23/iphone-6-plus-bending-pockets/) under pressure in their pockets.
Increasingly reliable reports (http://www.macrumors.com/2015/06/17/iphone-6s-7000-******-aluminum-kgi/) of 7000 ****** aluminum for the iPhone 6s followed by hands-on impressions (http://www.macrumors.com/2015/07/17/leaked-iphone-6s-plus-images/) of a "stronger body" and ultimately some measurements (http://www.macrumors.com/2015/08/10/iphone-6s-addresses-bendgate-video/) showing thickening of the shell's weak points have all pointed toward Apple making some changes to improve the strength and durability of the next iPhone.
MacRumors has recently received data on the elemental composition of the iPhone 6s shell, revealing that the aluminum alloy being used by Apple does indeed include roughly 5 percent zinc, which is in line with many 7000 ****** alloys and **t found in the iPhone 6 shell. A just-published video from Unbox Therapy (https://www.youtube.com/watch?v=ChUsy8gWwvo) is showing similar results, as well as test results showing a significantly stronger body more resistant to bending.

Interestingly, the data we received showed high iron levels of around 8 percent on average, although the iron composition varies significantly among test samples. Unbox Therapy, however, is **t seeing particularly high levels of iron in its sample.
We've been told that some iron can be introduced into the shell during the milling process, which can account for some of the variability in measurements shared with MacRumors. The small quantities of iron at levels seen by Unbox Therapy can be used to enhance durability and make the material easier to work with during the casting process.

As shown in electron microscope images shared with MacRumors, the iPhone 6s shell is covered with a roughly 10-micron thick a**dized aluminum oxide layer to help protect against corrosion. The a**dization layer also enables Apple to introduce dyes for various color options.

Unbox Therapy also subjected the iPhone 6 and 6s shells to bending tests, finding that while the iPhone 6 shell began experiencing significant bending at roughly 30 pounds of pressure, the iPhone 6s shell withstood at least twice as much pressure before bending.
Apple is expected to unveil the iPhone 6s and 6s Plus at a media event on September 9. If tradition holds, the company would begin taking pre-orders a few days later and officially launch the new phone on Friday, September 18. The iPhone 6s should appear largely identical to the iPhone 6 but contain a number of hardware upgrades including Force Touch support, a new A9 chip with 2 GB of RAM, camera improvements, and more. A new rose gold or pink color option has also been rumored.
