aluminium The tensile strength of 7039 aluminum alloy is only 432mpa, while that of 7022 aluminum alloy is up to 520mpao. The other characteristic of the alloy is that there are many kinds of transition elements, such as Mn and Cr as recrystallization inhibitors, Zr and Ti as grain refiners, By analyzing and testing the microstructure of the alloy, we can explain the microstructure theoretically and have a comprehensive understanding of the relationship between the microstructure and properties of the alloy.
7022 aluminum plate sheet has good processability, corrosion resistance, weldability, fatigue strength, etc. the yield strength of the alloy is close to the tensile strength, and the specific strength is high, so it is widely used in aviation manufacturing industry.
7022 aluminum plate sheet is mainly used for blowing mould and filling mould, and has a good market prospect.
