7020 aluminum is a high-strength wrought aluminum alloy primarily alloyed with zinc (Zn) and magnesium (Mg). As a heat-treatable alloy, it belongs to the 7000 series and is known for its excellent weldability, corrosion resistance, and fatigue strength, making it ideal for structural applications, especially in transportation and aerospace. Compared to 7075, it offers slightly lower strength but better weldability and corrosion performance, especially in marine or humid environments.
