Commonly used in competition bikes, the 7000 series aluminum is 60% stronger than regular aluminum alloys, yet it offers one-third of the stainless steel’s density. In the case of the Apple Watch, the Cupertino giant has treated the lightweight metal with microscopic zirconia beads, which give the metal a nice satin finish.
New aluminum alloy might not be the only innovative feature in the iPhone 6 family. Recent report suggests that the successor of iPhone 6 Plus will pack a Force Touch sensor.
Apple is expected to unveil the next iPhone family at some point in September. Until we hear an official word from Cupertino, we suggest that you take all rumors with a grain of salt.
