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 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 aircraft provides valuable experience for the promotion of domestic new materials in  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.
