The upcoming ‘iPhone 6s’ and ‘iPhone 6s Plus’ phones are expected to use a stronger 7000 Series aluminum body. A custom alloy designed for the Apple Watch Sport, 7000 Series aluminum is sixty percent stronger than standard aluminum alloys and just as light.
An elemental composition analysis of a claimed iPhone 6s shell performed by MacRumors gives us a deeper insight into the next iPhones’ Bendgate-proof body.
For starters, the claimed part showed high iron levels of around eight percent on average. Not only does using iron enhance durability but makes the material easier to work with during the casting process.
