iPhone 8 Chassis Frame From Stainless Steel Instead of Aluminum..
Apple is expected to adopt a forged stainless steel crafting process for its glass-encased “iPhone 8″, rather than use traditional aluminum CNC machining
Taiwanese sources from the upstream supply chain apparently confirmed the transition on Tuesday, according to DigiTimes, with component orders expected to be shared between Foxconn and U.S.-based Jabil.
The next-generation iPhone is expected to abandon its conventional aluminum back cover design and will adopt a new design using two reinforced glass panes and a metal frame in the middle. The metal bezel will be made of stainless steel using a forging process to enhance its sturdiness and reduce costs and manufacturing time.
The stainless steel process was last used by Apple in the iPhone 4s handset, which encased a glass sandwich” chassis in two CNC-machined steel bands. However, every succeeding iPhone iteration has used aluminum because the alloy offers heightened structural rigidity while remaining relatively lightweight.
