Is Sapphire Heavier And Thicker Than Gorilla Glass?


From reducing the sizes of bezels on the iPad, to using a stronger glass to make its iPhone screens (meaningsapphire glass that you could have enhanced strength using a thinner piece of glass), Apple is always looking for ways to cut on the size of its products: with each new generation device ideally being thinner and lighter than the one that came before it.

In terms of direct comparisons, this proves problematic for sapphire — particularly when combined with the rumors that the iPhone 6 will feature a larger “phablet” screen. Sapphire is around 67 percent heavier than Gorilla Glass, with a density of 3.98 g/cm3 compared to the 2.54 g/cm3 used for Apple’s existing iOS devices.

In a blog post, Corning also points out that Apple may have difficulty achieving a comparable thinness should they opt to replace Gorilla Glass with sapphire altogether. While it may be true that sapphire glass is typically thicker than Gorilla Glass, Aero-Gear disputes that this is a significant issue: noting that its thinnest Gorilla Glass product carries an overall thickness of .55mm, including the bonding adhesive — compared to a comparative sapphire product, which has a thickness of .6mm (again, with bonding adhesive).The difference between these two is 0.05mm — roughly the equivalent of a human hair.

Concerns about thickness also ignores a recent Apple patent, which describes an alternative way of cutting wafer-thin sapphire pieces using an industrial laser.
