Abstract: A glass article comprising an alkali aluminosilicate glass that is formable by down-draw processes for example slot- and fusion-draw to thicknesses of 125 μm or less and is capable of being chemically strengthened by ion-exchange to achieve a compressive stress at its surface of at least 950 MPa, in some embodiments at least about 1000 MPa, and in other embodiments at least about 1100 MPa. The high surface compressive stress allows the glass to retain net compression and thus contain surface flaws when the glass is subjected to bending around a tight radius. The glass may be used in foldable display applications.
