The invention relates to aluminosilicate glass, which is prepared from the following components in percentage by mass: 61 percent to 69 percent of SiO2, 7.5 percent to 13 percent of Al2O3, 14 percent to 19 percent of Na2O, 1 percent to 4 percent of K2O, 1 percent to 4.6 percent of MgO, 0.1 percent to 3.5 percent of CaO, 0 percent to 0.8 percent of SrO, 0 percent to 3 percent of ZnO and 0.05 percent to 0.5 percent of ZrO2. Wherein the following formulas are met by taking the mass percent of the components into the formula: (ZrO2 + ZnO + SrO)/Al2O3 is more than or equal to 0.05 and less than or equal to 0.25, and (Na2O + K2O)/(MgO + CaO + SrO) is more than or equal to 3.2 and less than or equal to 4.8. The prepared aluminosilicate glass has relatively high Vickers hardness, the ion exchange degree of the glass and fused salt is appropriate, the prepared chemically-tempered glass has relatively high surface compressive stress and hardness and balanced linear expansion coefficient and Young modulus, and the chemically-tempered glass is easy to bend and deform, not easy to break and relatively good in scratch resistance and weather resistance.
