7A04 Aluminum alloy sheet plate profile forgings
7A04 aluminum alloy sheet plate profile forgings is a heat treatment and strengthening alloy of Al-Zn-Mg-Cu system. Its strength is higher than that of hard aluminum. It is characterized by its yield strength close to tensile strength and plasticity, and its sensitivity to stress concentration is strong, especially when subjected to vibration load and repeated static load. Therefore, the design of parts, the manufacturing process and the assembly process need to strictly avoid the stress concentration and the formation of additional stress. The heat resistance of the alloy is poor, and it will soften rapidly when the temperature is higher than 125, and the stress corrosion resistance of thick and thick parts is poor in short and transverse.
The main stress parts of 7A04 alloy aluminum alloy sheet plate profile forgings is widely used in aircraft structures, such as beams and stringers, bulkheads, ribs, skin, joints, undercarriage parts etc.. It can produce all kinds of semi-finished products, such as plate, strip, section, bar, wall, pipe, wire, free forgings and die forgings.

The short transverse stress corrosion resistance of the thick and large parts of the alloy is poor. There are mainly plate and extrusion parts.

The main varieties are sheet, profile, extruded wall plate and bar, forgings and so on. There are three kinds of T6, T73 and T74 in use. The ingot of this alloy is more difficult than 7A04 alloy. It is suitable for hot forming, such as rolling, extrusion, forging and so on. It can make all kinds of parts of size and shape.
