Since the wear resistance of sapphire glass is much higher than that of other types of glass, Apple has moved sapphire glass to mobile phones since Apple 5 to improve the wear resistance!
Although Foxconn has only completed the assembly of a small number of products at present, it is a milestone breakthrough, because the production of the iPhone 6 screen covered by Sapphire instead of the iPhone 5S screen covered by Corning gorilla glass requires extremely complex manufacturing process.
According to the report, apple currently consumes 10% of the world's Sapphire products. IPhone 5 is Apple's first Apple device with sapphire material. The camera of the phone is covered with a layer of sapphire glass to protect the camera. Later, apple used the material on the home key of iPhone 5S.
According to another source, apple and GT advanced technologies signed a $578 million contract to build a sapphire processing plant in Arizona. Cook confirmed this in an interview with ABC Radio.
It is predicted that sapphire glass will wear much more than other types of glass, and may be equipped with precision instruments such as watches, such as Iwatch, a smart watch device that has not been confirmed by apple.
