As a relatively mature lightweight and high-strength alloy material, aluminum alloy is widely used in aerospace. Aluminum alloy material is generally used as a structural material, which has higher specific strength and better processing performance than steel.
In the aerospace field, aluminum alloy materials with high strength, high toughness and strong corrosion resistance are mainly developed to meet the harsh operating conditions of aerospace. The widely used alloy series are 2000 and 7000 aluminum alloys and Al-Li alloy materials.
High-strength aluminum alloy sheets with excellent performance are mainly used in the aerospace field. Because aerospace products have extremely high requirements for weight reduction, aluminum alloy sheets with high specific strength are the preferred materials for aerospace. Among Aerospace aluminum sheets, 7000 series high-strength and high-toughness aluminum alloy sheets and 2000 series medium-strength and high-toughness aluminum alloy sheets play an important role.
