Dispersion strengthened high strength and high conductivity pure aluminum products are generally used in aerospace (such as aircraft landing gear, wing beam cover, seat guide rail, etc.), military, transportation and other fields. The dispersion strengthened ultrahigh strength aluminum alloy bars, plates, profiles and forgings with excellent properties were prepared by powder metallurgy. Dispersion strengthening and fine grain strengthening are introduced into the traditional aging strengthening high strength aluminum alloy, while maintaining the ductility of the high-strength aluminum alloy, the strength and hardness of the high-strength aluminum alloy are greatly improved.
