The invention discloses an Al-Mg-Si series aluminum alloy with high long-term thermal stability and high crushing performance and a preparation method and application of the Al-Mg-Si series aluminum alloy with the high long-term thermal stability and the high crushing performance. The Al-Mg-Si series aluminum alloy with the high long-term thermal stability and the high crushing performance comprises Al and the following components in percentage by mass: 0.8%-1% of Mg, 0.4%-0.6% of Si, 0.15%-0.5% of Cu, 0.15%-0.5% of Fe, 0.1%-0.5% of Mn and 0.05%-0.2% of Ti, and the ratio of Mg to Si is 1.5-2.0. On the basis of matching of all the components, the aluminum alloy material with high strength, high long-term thermal stability and high crushing performance is obtained, and the use requirement for high comprehensive performance in the automobile industry can be well met. The invention further provides a preparation method and application of the Al-Mg-Si series aluminum alloy with the high long-term thermal stability
