摘要： The disclosure relates to an aluminum alloy and a component part prepared therefrom. The aluminum alloy comprises: 7-9 wt% of silicon (Si), 0.2-0.7 wt% of manganese (Mn), 0.09-0.4 wt% of iron (Fe), 0.1-0.3 wt% of vanadium (V), 0.1-0.2 wt% of titanium (Ti), 0.01-0.03 wt% of strontium (Sr), and the balance being aluminum and inevitable impurities, wherein the weight ratio of the manganese (Mn) to the iron (Fe) is not less than 1. The aluminum alloy of the disclosure can be exempt from heat treatment process after casting in the processing process, so as to contribute to energy conservation and emission reduction, and the component part prepared therefrom can achieve desired mechanical properties.
