The invention relates to aluminosilicate glass, tempered glass, a preparation method of the aluminosilicate glass and the tempered glass and a glass product. The aluminosilicate glass comprises the following components: 58%-67% of SiO2, 8%-14% of Al2O3, 12%-16% of Na2O, 4%-9% of K2O, 7%-12% of MgO, 0-2% of ZrO2 and 1%-4% of B2O3, and the ring crush coefficient W of the aluminosilicate glass is 2.6-4.1. The ring crush coefficient W is calculated according to the following formula: a, b, c and d in the # imgabs0 # formula are respectively the mass percentages of Al2O3, K2O, MgO and B2O3 in the aluminosilicate glass. The aluminosilicate glass adopts the specific composition, the composition meets the specific ring crush coefficient W, and after the aluminosilicate glass is subjected to chemical tempering treatment for a short time, tempered glass with high strength can be obtained. 本申请涉及一种铝硅酸盐玻璃、钢化玻璃及其制备方法、玻璃制品。上述铝硅酸盐玻璃包括以下组分：58％～67％的SiO2、8％～14％的Al2O3、12％～16％的Na2O、4％～9％的K2O、7％～12％的MgO、0～2％的ZrO2和1％～4％的B2O3，所述铝硅酸盐
