description The invention provides a refinement method of aluminium alloy and aluminium alloy manufactured by the method. The method comprises the steps of: (1) melting aluminum alloy at 770-800 DEG C; (2) adding an aluminum refining agent in accordance with 0.2-0.6 wt.% of the raw material of aluminum alloy, and insulating at 70-800 DEG C for 5-120 min, wherein the aluminum refining agent comprises, calculated by atomic percentage, 50-60% of Zr, 20-25% of Co, 14-18% of Al and 5-7% of Ag; preferably, the aluminum alloy refiner is amorphous alloy. The invention has the beneficial technical effects that the refinement of the A356 aluminum alloy grains can obtain A356 aluminum alloy with superior mechanical properties, so as to meet the material requirements of aluminum alloy wheel. The method improves the strength and ductility of the alloy, and the A356 is quite suitable for the manufacture of automotive aluminum alloy wheels.
