Abstract: The present invention relates to a method for manufacturing a high elastic aluminum alloy comprising: a first step for forming a primary molten metal by charging pure aluminum (pure Al) and a Al-5B master alloy into a smelting furnace; a second step for forming a secondary molten metal by charging a Al-10Ti master alloy into the primary molten metal; a third step for forming a third molten metal by charging a silicon (Si) element into the secondary molten metal; a fourth step for inserting argon gas into the third molten metal; and a fifth step for tapping the third molten metal, which the argon gas is inserted into, to a mold. According to the present invention, the method for manufacturing a high elastic aluminum alloy is capable of improving elasticity due to uniform distribution of a boride, and reducing the processing costs by stirring a molten metal by controlling the time and flow rate of argon gas which is used for a conventional degassing process in order to disperse boride uniformly inside an aluminum alloy molten metal in an aluminum alloy manufacturing process.
