The invention provides aluminum-silicon glass, reinforced aluminum-silicon glass and a preparation method and application of the aluminum-silicon glass and the reinforced aluminum-silicon glass, and the aluminum-silicon glass comprises the following components in percentage by weight of oxides: 46-60% of SiO2; 12% to 19% of Al2O3; 8%-15% of La2O3; 8%-14% of R2O, wherein R is at least one of Li and Na; 1% to 5% of Y2O3; and at least one of ZnO, Nb2O5, and B2O3. The elasticity modulus of the aluminum-silicon glass is larger than or equal to 105 GPa, and the double-ring strength is larger than or equal to 260 MPa. The aluminum-silicon glass provided by the invention is subjected to chemical toughening treatment, so that the reinforced aluminum-silicon glass can be prepared. The double-ring strength of the aluminum-silicon glass after chemical tempering can reach 1320 MPa or above, and meanwhile the aluminum-silicon glass has excellent comprehensive performance such as good acid resistance and alkali resistance and can be used as a transparent part and a window to be used in the fields of airplanes, ships, special vehicles and the like.
