Abstract Aluminum 7xxx series alloys contain zinc as the main alloying element, usually in combination with magnesium and copper. High-strength 7020 alloy is widely used in aerospace structures and is approved by the world’s leading airframe builders. For engineering applications this alloy is generally used in the T651 temper in order to provide maximum strength. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: AL-400. Producer or source: Alcoa Mill Products Inc.
