The invention discloses a low quenching sensitive aluminum alloy added with Ag and Ge at the same time. The aluminum alloy is subjected to alloying treatment of trace Ag and Ge elements. On the one hand, the Ag and a vacancy have higher binding energy by using the characteristic that the binding energy of the Ge element and the vacancy is far greater than that of elements such as Zn, Mg, Cu and the like and the vacancy, and the Ge and Ag elements added into the alloy are first bond with the vacancy during solid solution quenching so as to prevent the dispersion of solvent atoms of Zn, Mg, Cu and the like in the alloy and the separation of a thick second phase at a low solid solution quenching speed, effectively improve the quenching property of the aluminum alloy, reduce the quenching sensitivity of the aluminum alloy and provide a complete solid solution quenching tissue for obtaining a dispersed strengthening phase for follow-up ageing; and on the other hand, the added Ag can play a role ...
