The invention discloses a compressible series aluminum alloy with an energy absorption effect and a preparation method of the compressible series aluminum alloy, and belongs to the technical field of non-ferrous metal manufacturing. 0.6 to 0.7 percent of Si; 0.3 to 0.5 percent of Mn; cr: 0.1 to 0.2%; 0.1% to 0.15% of Sm; cu: 0.1 to 0.25%; 0.1 to 0.2 percent of Fe; the sum of the inevitable impurities is less than or equal to 0.15 And the balance of Al: 97.75 to 97 percent. The preparation method comprises the following steps: melting the raw materials in a smelting furnace, and carrying out electromagnetic stirring. And when the temperature of the molten aluminum reaches 720-760 DEG C, 1-2 Kg/t of Na3AlF6, Na2CO3 and CaF2 are added, argon is introduced, and degassing refining is conducted for 20-30 min. And when the temperature of the molten aluminum reaches 700-720 DEG C, the molten aluminum is cast into an aluminum bar. And the casting rod is placed in an annealing furnace and cooled to the room temperature. And peeling off a skin of 6-10 mm. And the cast ingot is heated to 460-540 DEG C and extruded, and the aluminum alloy profile in the T4 state is obtained. And the T6 aluminum alloy profile is obtained. The invention has the beneficial effects of high temperature resistance, high yield point and compressibility.
