The application provides a high-
casting-performance
beryllium aluminum
alloy and a preparation method thereof, and belongs to the technical field of
alloy materials.The preparation method comprises the following steps: preparing materials according to the weight percentages of Be ingots, Al ingots, Ag ingots, Co sheets, Si and La metals; placing the Ag ingots, the Co sheets, the Si and the La metals at the bottom of a
crucible, then sequentially placing the Al ingots and the
beryllium ingots into the
crucible, refining, and obtaining a melt; uniformly stirring the melt, then gradually cooling the melt to a pouring temperature, then pouring the melt into a prefabricated
ceramic mold shell, and standing for 3-5 minutes in a furnace and cooling outside the furnace.The
beryllium aluminum
alloy has a uniform and dense structure, good fluidity, high
casting performance, and is easy to be cast into a shape, and has fewer
casting defects.
