An aluminium alloy casting rod specially used for rotary-swaged D061 wheel-type automobile hubs comprises the following components by weight: 0.70-0.80% of Si, 0.20-0.3% of Fe, 0.20-0.30% of Cu, 0.06-0.10% of Mn, 0.90-1.20% of Mg, 0.05-0.15% of Cr, not more than 0.05% of Zn, not more than 0.05% of Ti, and the balance of Al. The process comprises the following steps: weighing the components of Si, Fe, Cu, Mn, Cr, Zn, Ti, and Al, melting the components in a melting furnace, when the temperature reaches 735+/-5 DEG C, removing scum, adding Mg according to the weight ratio, uniformly stirring, and removing slag to prepare aluminium alloy melt; introducing the aluminium alloy melt into a standing furnace, when the temperature reaches 735+/-5 DEG C, adding refining powder and performing slag removing and refining; degassing with argon and an Al-Ti-B rod, and refining; putting the refined aluminium alloy melt into a standing furnace at a temperature of 730 DEG C-740 DEG C, standing for 30 min, performing casting molding by a hot-top casting machine, treating the cast aluminium alloy casting rod, performing uniform annealing treatment and cooling treatment, and performing detection to obtain the aluminium alloy casting rod specially used for rotary-swaged D061 wheel-type automobile hubs when detection shows that the product is qualified.
