A glass composition includes from 55.0 mol % to 75.0 mol % SiO2; from 8.0 mol % to 20.0 mol % Al2O3; from 3.0 mol % to 15.0 mol % Li2O; from 5.0 mol % to 15.0 mol % Na2O; and less than or equal to 1.5 mol % K2O. The glass composition has the following relationships: Al2O3+Li2O is greater than 22.5 mol %, R2O+RO is greater than or equal to 18.0 mol %, R2O/Al2O3 is greater than or equal to 1.06, SiO2+Al2O3+B2O3+P2O5 is greater than or equal to 78.0 mol %, and (SiO2+Al2O3+B2O3+P2O5)/Li2O is greater than or equal to 8.0. The glass composition may be used in a glass article or a consumer electronic product.
