The rapid advancement of the aerospace industry has imposed greater demands on materials science. Aluminum alloys, as an important lightweight structural material, have drawn wide attention in this field. To meet the strict conditions in aerospace, high-strength, high-toughness, highly corrosion-resistant, and easily processable Al-Cu-Mg and Al-Zn-Mg aluminum alloys are mainly developed. This book aims to investigate the application research of typical Al-Cu-Mg aluminum alloys in the field of aerospace, discussing material properties, alloy design, fabrication techniques, performance evaluation while also anticipating future development prospects for aluminum alloys in aerospace.The book can be used as a textbook for graduate students majoring in Materials Science and Engineering, as well as for undergraduate students majoring in Materials Science. It can also serve as a reference book for engineering and technical personnel.
