While some analysts have predicted the iPhone 7 to hit retail lines as early as September this year, leaks from Value Walk reveal that the date could be pushed back to early next year. Christened Liquidmetal, the Series 7000 aluminum is exclusively licensed for use by the Cupertino giant but not many know that Atakan Peker was the man who developed it. Knowing the main properties of this alloy, we can now dream of having an iPhone 7 that is as light as breeze and sleek beyond imagination. However, it is set to be way stronger than you can imagine despite coming in a slim form factor. If insider buzz is to be believed, then Apple will also add sapphire glass to the iPhone 7. This will bid goodbye to the nag that Apple cares little for durability of its iDevices. For the greedy fans who must already have begun to structure a bendable iPhone 7, you must know that the material will not be literally bendable but the screen could have a flexibility quotient associated with it.
