According to a report last week, it was suggested that Apple could be thinking of using 7000 series aluminum for their next-gen iPhone, the iPhone 6s and 6s Plus. Why is this significant? Well apparently the 7000 series is tougher compared to what Apple is using at the moment, thus making it more durable and less prone to “bendgate”.
That being said if you wanted more evidence that this is the direction Apple is headed, KGI Securities analyst Ming-Chi Kuo has since “confirmed” in his latest investor’s note that Apple will indeed be using the material. The note was obtained by Japanese Apple blog Mac Otakara (via MacRumors) and according to the note, the use of the 7000 series could result in an iPhone that is slightly taller and thicker compared to its predecessor.
To be more specific, the iPhone 6s would be 0.15mm taller and because of the rumored addition of Force Touch, it will also be 0.2mm thicker. While most users might not be able to tell the difference, it could result in some of your existing cases/accessories to not fit the new iPhones, but at the moment it is too early to tell.
Kuo also adds that Apple will introduce a new color option in the form of a rose gold finish, similar to what they have done with the Apple Watch. Take it all with a grain of salt for now, obviously, but Kuo has been pretty accurate with his Apple predictions in the past, so even though they are rumors and speculation, there might be some truth to them.
