Claim 3:
4. A preparation method of the casting alloy according to claim 1, comprising the following steps:
step 1): completely cleaning bulk particles of Al, Co, Cr, Cu, Fe, Ni, and Ti elementary substances, and weighing according to a proportion;
step 2): vacuumizing a vacuum smelting furnace to not more than 6.0×10-4 Pa, and introducing a protective gas; adding Ti into the vacuum smelting furnace for deoxidation, adding the rest of the elementary substances for melting, and stirring for smelting; and
step 3): after the smelting is completed, pouring an alloy obtained in step 2) into a water cooling plate-shaped copper mold for casting, cooling to room temperature, and collecting a finished product.
