The light magnesium alloy automobile hub is prepared from pure magnesium, pure zinc, a magnesium-zirconium intermediate alloy, a magnesium-antimony intermediate alloy, a magnesium-cerium intermediate alloy, a magnesium-manganese-lanthanum alloy and modified boron carbide. The magnesium-zirconium intermediate alloy is an Mg-30wt.% Zr intermediate alloy, the magnesium-antimony intermediate alloy is an Mg-10wt.% Sb intermediate alloy, the magnesium-cerium intermediate alloy is an Mg-20wt.% Ce intermediate alloy, and the magnesium-manganese-lanthanum alloy is an Mg96Mn3La1 alloy. The magnesium alloy comprises the following elements in percentage by weight: 3%-5% of Zn, 0.8%-1.0% of Zr, 0.3%-0.7% of Sb, 3%-6% of Ce, 0.6%-0.9% of Mn, 0.2%-0.3% of La, 0.3%-0.4% of modified boron carbide and the balance of Mg. The magnesium alloy prepared by the method disclosed by the invention has higher tensile strength, shows good mechanical properties, is not easy to deform and crack during use, and reduces the maintenance cost.
