Corning® Gorilla® Glass 3 with Native Damage Resistance™ is an alkali-aluminosilicate thin sheet glass that is better able to survive the real-world events that most commonly cause glass failure. With its new core composition, this glass enables improved damage resistance and toughness by helping to prevent the deep chips and scratches that cause glass to break.

Gorilla ® Glass 3 with NDR™
Soda Lime Glass
Putting Gorilla® Glass 3 with NDR™ to the Test.
It takes more load to initiate radial cracks in the glass.
Devices benefit from greater retained strength.
Corning Gorilla Glass 3 with NDR™ exhibits tighter strength distribution.
Greater damage resistance
Enables the use of thinner cover glass
Enables greater strength
Greater retained strength
Scratches are less visible
