7B04 aluminum plate sheet
7B04 alloy aluminum plate sheet is a typical Al-Zn-Mg-Cu system, which is based on the development of 7A04, which is based on the development of alloy, the alloy and 7075 alloy, mainly on the basis of their Fe, Si impurities content, which makes the strength of the alloy on the basis of 7075 alloy, improve the anti stress corrosion performance and fracture toughness.
7B04 alloy aluminum plate sheet is a kind of high strength aluminum alloy, which is the main aluminum alloy in the structure of a certain aircraft in China. 7B04 alloy by high purity, melt purification and new heat treatment process (T74, T73), at the same time, greatly improve the fracture toughness, resistance to stress corrosion cracking, etc., these excellent comprehensive performance to maintain flight safety, improve the flying speed, increase the use of life is important.
