7A04 aluminum alloy is the most commonly used super-durable aluminum, a high-strength alloy that can be strengthened by heat treatment. 7A04 aluminum sheet is usually used under the condition of quenched artificial aging. At this time, the strength is much higher than that of general duralumin, but the plasticity is lower. Extruded semi-finished products and aluminum clad plates that are not too thick in cross section have good corrosion resistance and tend to have stress concentration. The spot weldability is good, the gas welding is poor, the machinability is good after the heat treatment, and the annealing state is low.
