Apple said at its fall conference this year that the iPhone 15 Pro and iPhone 15 Pro Max are made of aluminum alloy and thermally bonded with grade 5 titanium. To test whether the company's claims were accurate, YouTuber Zach showed viewers how easily Apple's $1,199 iPhone breaks when bent during a durability test, and shortly thereafter polished the flagship with an angle grinder.

The blogger has often criticized Apple for its anti-consumer business practices, but praised the company's mass production of titanium cases.
While much of Zack's JerryRigEverything focuses on durability testing of smartphones and tablets, the YouTuber doesn't shy away from criticizing Apple and its practices that make repairs difficult. This time, Zach expressed great dissatisfaction when disassembling the broken iPhone 15 Pro Max, because countless screws needed to be removed before all parts could be separated from the titanium alloy body.
When only the solid metal frame is left, a razor blade can be used to check whether the interior is made of aluminum. The titanium portion of the exterior can be easily seen in the video, but in order to see how Apple thermally bonded the two metals together, Zach decided to use an angle grinder.
He cut the body in half to show a cross-section of the iPhone 15 Pro Max's frame, noting two different tones of metal, with silver aluminum on the inside and "gold" titanium on the outside. He concluded through measurements that the thickness of the titanium metal used in iPhone 15 Pro and iPhone 15 Pro Max is 1 mm. He also understood that bonding the two metals together is a complex process, and Apple has done a very good job in this regard and has received praise for the quality of its work.
Since titanium itself is a softer material, it scratches very easily, and according to previous durability tests Zack has done on his channel, the new fusion process ends up making the entire body noticeably weaker. Therefore, we recommend that every user who has upgraded to iPhone15Pro and iPhone15ProMax invest in a thicker protective case to prevent any irreparable damage, because this is only a small investment, but it can protect you from overhauling the device.
