Corning Gorilla Glass

Corning Gorilla Glass 5: Corning’s latest composition was formulated to address breakage the #1 consumer complaint, according to Corning’s research. The new glass is just as thin and light as previous versions, but has been formulated to deliver dramatically improved native damage resistance allowing improved in-field performance. Corning Gorilla Glass 5 has been tested for performance when subjected to sharp contact damage, such as asphalt and other real-world surfaces.

Benefits

Enhanced retained strength after use.
High resistance to scratch and sharp contact damage.
Improved drop performance.
Superior surface quality.

Applications

Ideal protective cover for electronic displays in:
- Smartphones
- Laptop and tablet computer screens
- Wearable devices
Touchscreen devices
Optical components
High strength glass articles

Refractive Index (590 nm)
Core glass**	1.50
Compression layer	1.51
Photo-elastic constant	30.3 nm/cm/MPa

** Core index is used for FSM-based measurements since it is unaffected by ion-exchange conditions.

Chemical Durability

Durability is measured via weight loss per surface area after immersion in the solvents shown below. Values are highly dependent upon actual testing conditions. Data reported is for Corning Gorilla Glass 5.

Putting Corning Gorilla Glass 5 to the test.

Greater damage resistance (upto 1.8X) with deep abrasion.
Faster chemical strengthening with high Compressive Stress and deeper depth of compression
- Shallower check depth with higher abrasions levels
Enables thickness reduction
