Corning Gorilla Glass 6 is twice as strong as Gorilla Glass 5
Corning Gorilla Glass 6 is official today and is currently being evaluated by multiple customers, and is expected to reach the market in the next several months.Subjected to a new and rigorous test methodology in Corning’s labs, on average, Gorilla Glass 6 survived 15 consecutive drops from 1 meter onto rough surfaces and is up to 2x better than Gorilla® Glass 5. Under the same test conditions, competitive glass compositions didn’t even survive the first drop. Gorilla Glass 6 also survives at higher heights than Gorilla Glass 5.
Corning’s proprietary fusion manufacturing process is at the core of its leadership in glass technology and the cover glass industry. This extraordinarily precise, highly automated draw process produces a thin sheet cover glass with pristine surface quality, outstanding optical clarity and inherent dimensional stability – qualities essential for cover glass for consumer applications.
The process begins when raw materials are blended into a glass composition, which is melted and conditioned. The molten glass is fed into a trough called an “isopipe,” overfilling until the glass flows evenly over both sides. It then rejoins, or fuses, at the bottom, where it is drawn down to form a continuous sheet of flat glass that is so thin it is measured in microns. The glass is untouched by human hands or anything else that could introduce flaws into the surface.
The composition of Corning® Gorilla® Glass enables a deep layer of chemical strengthening through an ion-exchange process where individual glass parts are cut from the “mother sheet” and undergo an ion-exchange process.
“As consumers become more dependent on their smartphones, the opportunity for potentially damaging drops is also on the rise. Now more than ever, it’s critical that the cover glass provides outstanding protection,” said John Bayne, vice president and general manager, Corning Gorilla Glass. “Corning Gorilla Glass 6 improves upon Gorilla® Glass 5 by surviving drops from higher heights, but, more importantly, has been engineered to survive multiple drops.”
“Gorilla Glass 6 is an entirely new glass composition that can be chemically strengthened to give it significantly higher levels of compression than is possible with Gorilla Glass 5. This enables Gorilla Glass 6 to be more resistant to damage,” said Dr. Jaymin Amin, vice president of technology and product development, Corning Gorilla Glass and Corning Specialty Materials. “Moreover, with breaks during drops being a probabilistic event, the added compression helps increase, on average, the likelihood of survival through multiple drop events.”
“In addition to addressing drop height and drop frequency, Gorilla Glass 6 was also developed to meet the requirements of modern designs that use glass for more than 85 percent of the enclosure. With both its aesthetic and performance advantages, glass is on the right side of the technology curve and will continue to be the material of choice for mobile consumer electronics,” said Scott Forester, division vice president, Marketing and Innovation Products, Corning Gorilla Glass.
