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.

7A04	B95(Russia)	The yield strength to tensile strength, low ductility, sensitivity to stress concentration effects, especially the repeated static load under vibration load and the situation is more obvious, therefore need to strictly avoid stress concentration factor and the formation of additional stress in parts of the design, manufacture and assembly process. The short transverse stress corrosion resistance of the thick and large parts of the alloy is poor. There are mainly plate and extrusion parts.	480~570	<125

7B04 aluminum alloy sheet profile forgings

7B04 alloy is further purified and developed on the basis of long term use of 7A04 alloy. That is to improve its fracture toughness properties by controlling Fe and Si impurity elements. 7B04 alloy has been used in T6 state for a long time, and its strength is high. The characteristic is that the yield strength is close to the mild tensile, low plasticity and poor stress corrosion resistance.
7B04 aluminum alloy sheet profile forgings is a relatively mature high purity aluminum alloy in China. It is a large aluminum alloy used on military aircraft in China. Parts of the machine account for 60% of the total aluminum alloy consumption, and the consumption of the single machine is about 20t, which achieves stable batch supply. Varieties include plates, thick plates, profiles, extruded panels, bars and forgings. The successful application of 7B04 alloy to military aircraft provides valuable experience for the promotion of domestic new materials in military and civil aircraft.

Alloy	Alloy Series	Main Features	σb Value/MPa	Working Temperature/ºC
7B04	B95(Russia)	The fracture toughness of 7A04 alloy is higher than that of 7A04 alloy by 10%~15%. 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.	440~590	<125
