Quantity:

7A04 is the most commonly used super-durable aluminum, a high-strength alloy that can be strengthened by heat treatment. It is usually used in the quenched artificial aging state. 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 have a tendency to stress concentration. The spot weldability is good, the gas welding is poor, the machinability is good after heat treatment, and the annealing state is low.
