What is Gorilla Glass?
Gorilla Glass is Corning's ion-exchange strengthened aluminosilicate cover glass, in which a potassium-for-sodium exchange in molten KNO₃ builds a deep surface compression layer. It is specified for thin fusion-drawn cover panels (0.4–2 mm) that need scratch and impact resistance, with about 350 MPa tensile strength and service to 200 °C; GG3, GG5 and Victus differ in exchange chemistry and drop performance. All cutting, drilling and edging must be completed before ion exchange, and the glass cannot be welded or re-formed by the user. Sapphire is the alternative when scratch resistance outranks cost. Gorilla Glass has a density of 2.42 g/cm³ (0.0874 lb/in³), lighter than 78% of glass grades. Gorilla Glass has a tensile strength of 350 MPa (50.8 ksi), stronger than 91% of glass grades. Elongation at break is 0% and the elastic modulus is 72 GPa (10.4 Msi).

Gorilla Glass has a density of 2.42 g/cm³ (0.0874 lb/in³), lighter than 78% of glass grades.
Mechanical12
Gorilla Glass has a tensile strength of 350 MPa (50.8 ksi), stronger than 91% of glass grades. Elongation at break is 0% and the elastic modulus is 72 GPa (10.4 Msi).
Thermal5
Gorilla Glass is rated for continuous service to 200°C (392 °F). It conducts heat at 1 W/m·K (0.578 BTU/hr·ft·°F), worse than 77% of glass grades. Thermal expansion is 7.9 µm/m·K (4.39 µin/in·°F).
Electrical5
Gorilla Glass is an electrical insulator with a dielectric strength of 15 kV/mm (381 V/mil) and a resistivity of 1×10¹² Ω·m.
Chemical & Environmental2
Corrosion resistance is excellent (90/100), better than 73% of glass grades.
Sustainability4
Producing a kilogram of Gorilla Glass takes about 35 MJ of energy and emits 2.6 kg of CO₂ — less than 71% of glass grades. Typical recycled content is 3%.
Manufacturability2
Gorilla Glass's machinability is not recommended (5/100, worse than 92% of glass grades).

Working with Gorilla Glass
Is Gorilla Glass easy to machine?
Cut, drill and edge-finish only in the un-strengthened state using diamond scribe/CNC grinding or laser (filamentation) cutting; never machine after ion exchange or the compressive layer releases and the part shatters.
Can Gorilla Glass be welded?
Not weldable; join by optically clear adhesive (OCA), silicone gasketing or glass-frit/laser sealing to another glass in the annealed state.
Can Gorilla Glass be formed, bent or molded?
Flat sheet is fusion-drawn to final thickness (0.4–2 mm); 2.5D/3D shapes are hot-formed on graphite tooling near the softening point (~850–900 °C) and then ion-exchanged in molten KNO₃ at 380–460 °C.

What surface finishes work on Gorilla Glass?
Standard finishes are optical polish, HF-etched anti-glare, AR/AF (fluorosilane) coatings and screen-printed ceramic/organic borders; avoid strong alkaline cleaners and any HF-bearing chemistry.

Gorilla Glass — frequently asked
What is Gorilla Glass used for?
Gorilla Glass is typically used for smartphone screens, tablet and laptop touch panel covers, wearable and smartwatch cover lenses, automotive interior display covers, appliance and HMI control panels and kiosk and POS touchscreens. In short: chemically strengthened glass.
What is the tensile strength of Gorilla Glass?
Gorilla Glass has a typical tensile strength of 350 MPa (50.8 ksi) — stronger than 91% of glass grades. Strength varies by condition: see the 3 listed tempers.
Is Gorilla Glass easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 92% of glass grades). Cut, drill and edge-finish only in the un-strengthened state using diamond scribe/CNC grinding or laser (filamentation) cutting; never machine after ion exchange or the compressive layer releases and the part shatters.

What is the maximum service temperature of Gorilla Glass?
Gorilla Glass is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
