7A04 alloy is a heat-treated strengthening alloy of Al-Zn-Mg-Cu system. Its strength is higher than that of hard aluminium. Its yield strength is close to tensile strength and its plasticity is lower. Its sensitivity to stress concentration is strong, especially under the condition of vibration load and repeated static load. Therefore, the design, manufacturing and assembly of parts need to strictly avoid stress concentration and additional stress factors. The heat resistance of the alloy is poor, and it will soften sharply when the temperature is higher than 125 C. The stress corrosion resistance of thick parts in short and transverse direction is poor.
